Choosing the right storage size for photovoltaic systems is crucial to increase self-sufficiency and achieve maximum savings. Whether it's an 800W balcony power plant or a 10kWp system – calculating PV storage size helps optimize self-consumption. A solar yield table allows for precise comparison of yields and cost savings.
Why calculating PV storage size is important
Correct sizing of the storage maximizes self-sufficiency and increases the self-consumption of solar power. Too small a capacity leads to unnecessary feeding into the grid, while too large a capacity causes unnecessary costs. According to market standards, the storage should comprise 1 to 1.5 kWh per kWp of PV power to achieve the highest economic efficiency.
For balcony power plants from 800W: 1-2kWh storage is the golden ratio for daily needs. For 10kWp systems, experts recommend 5-10kWh, as this provides the best cost-benefit ratio. This increases the degree of self-sufficiency from 30 percent without storage to up to 70 percent.
Calculation formula for storage size
The basic formula is: Storage capacity = night operation base load × desired reserve hours. Let's take a typical night load of 300W and 8 reserve hours: 300W × 8h = 2.4kWh of required storage. This method takes into account real household consumption and perfectly suits PV systems up to 10kWp.
For an 800W balcony power plant yield of around 700-900kWh per year, 1-2kWh of storage is ideal. For 10kWp with an annual yield of 10,000kWh, 5-10kWh is recommended to cover peak loads and maximize self-sufficiency. Adjust the formula to your location and consumption.
Market trends in solar storage
The market for PV storage is growing rapidly, with a focus on lithium-ion technology for higher efficiency. In Germany, installations are increasing by 40 percent annually, driven by falling prices and EEG subsidies. User profiles show: 60 percent of buyers are homeowners with 5-10kWp systems who want to increase their self-sufficiency.
Prices for 5kWh storage units are between 3,000-5,000 Euros, with amortization in 5-7 years. Balcony power plants with storage are booming among tenants, as plug-and-play solutions make entry easier. Regional yield differences influence storage choice: Southern Germany benefits from higher yields.

In the world of solar energy, users often encounter terms like watts, kWp, Ah, Wh, amperes, and volts. These units are essential for correctly understanding power, capacity, and energy consumption. This article explains the conversions step by step and offers practical tools such as calculators and tables.
Converting watts to kWp
Converting watts (W) to kilowatt-peak (kWp) is simple: divide the watt number by 1000, as 1 kWp corresponds to exactly 1000 watts. For a typical balcony power plant with 800 watts, this means: 800 watts = 0.8 kWp. This solar unit calculator formula helps to quickly evaluate the nominal power of solar modules. The meaning of kWp lies in the peak power under standard test conditions (STC), ideal for planning photovoltaic systems.
Converting Ah to Wh
Ampere-hours (Ah) indicate the charge amount of a battery, while watt-hours (Wh) indicate the usable energy. The Ah to Wh formula is: Wh = Ah × Volts (V). For 100 Ah and 12 V, the result is 100 Ah × 12 V = 1200 Wh. Converting Ah to Wh is crucial because storage batteries are often specified only in Ah, but consumers are billed in Wh or kWh. This allows for fair comparison of different batteries, regardless of their voltage.
Why convert storage batteries from Ah to Wh?Ah alone is deceptive because voltage is missing – a 100 Ah battery at 12 V delivers twice as much energy as at 6 V. Wh shows the actual runtime for devices like refrigerators or routers. In solar systems, this optimizes self-consumption and avoids misinvestments.
Amperes and volts: The difference
Amperes (A) measure the current flow, comparable to the amount of water per second in a river. Volts (V) represent the voltage, like the water pressure that drives the current. Amperes multiplied by volts result in watts (W): P = U × I (Power = Voltage × Current). With the water metaphor: Amperes (flow rate) × Volts (pressure) = Watts (energy transfer). This fundamental principle explains why solar calculators consider volts and amperes.

Today, balcony power plants with 600 and 800 watts of brand strength have arrived in many households. Thoughtful installation planning is necessary to securely attach the modules to balconies, flat roofs, or in gardens. The most important requirements are wind safety, material quality, correct alignment, and suitable accessory components such as mounting kits, cables, and antennas.
Balcony Power Plant Installation Guide for Various Locations
Different locations require different fastening solutions. The following basic principles apply to balcony power plants with 600 or 800 watts:
On the balcony: Rigidly mounted brackets on the railing or wall with precise alignment and securely screwed modules.
On flat roofs: Combination of aluminum or steel substructure and sufficient ballast to counteract wind loads.
In the garden: Ground mounting with hot-dip galvanized or aluminum bases fixed deep into the ground or onto concrete slabs.
Railing Types and Suitable Mounts
For mounting on a balcony railing, the geometry and material thickness are particularly crucial.
Round Railings (Round Bar)
Round railings with a diameter between approximately 40 and 65 mm are the most common. Special balcony power plant mounts with U-bolts or clamp mounts are used here. It is important that the mount covers not only the diameter but also the wall thickness of the railing. Many manufacturers offer mounts designed for 60-watt panels up to complete 600-watt systems, distributing forces evenly across multiple contact points.
Square or Rectangular Railings
For square or angular railing profiles, adjustable clamp mounts or rails with individually positionable clamps are useful. These mounts can be adapted to the height and orientation of the panel and provide stable support without damaging the railing. For 600W balcony power plants, you typically mount the module so that its longitudinal axis is parallel to the parapet and the clamps are tightened firmly on both sides.
In both cases, it is essential to fasten the bracket as intended by the manufacturer and never resort to improvised solutions such as cable ties or simple tensioning straps, as these cannot reliably bear wind loads.
Flat Roof and Terrace: Ballast and Wind Load
On flat roof surfaces and terraces, free-standing structures or light metal frames with concrete slabs or granite ballast are typically used.
Basic Principle of Ballasting
Ballasting (balcony power plant ballasting) serves to secure the mounting against tipping and slipping. Sensible flat roof installations, for example, use 20–50 kg concrete slabs per module or module pair, depending on the dynamic wind load and installation area. Many manufacturers of balcony power plant accessories offer pre-drilled concrete slabs or special ballast stones that are hooked into the profile frames.
Important Notes on Wind Safety
Wind load increases quadratically with speed. Therefore, a rough estimate is not sufficient. For 600-watt and 800-watt modules, constructions designed for the local wind zone or checked by a specialist company are recommended. Typical anchor quantities are 4–6 anchor points per module row, depending on the inclination and area.
Antenna Construction Versus Improvised Fastenings
While improvised aids like cable ties or simple straps can help during assembly, they are never suitable for permanent fastening. Proper PV mounting accessories with screws, clamps, and tensioning devices made of aluminum or stainless steel will bear the loads for years and comply with the mechanical requirements of the standards.
Installing a 600W Balcony Power Plant: Example Procedure
A typical installation procedure for a 600W balcony power plant on a balcony railing is as follows:
Check railing height, diameter, and load-bearing capacity.
Select a suitable mount designed for round or square railings and the desired panel width.
Mount the bracket using the provided screws and clamps, without overtightening the railing.
Insert and fix the solar module with module clamps or screw straps.
Connect the IP67 cables and route them to the socket or inverter.
For 800-watt systems, a second panel is often mounted next to or behind the first, with the bracket and mounting structure needing to securely compensate for the doubled area and increased wind load.
Important Aspects of Cables and Connections
IP67 Cables and UV Resistance
The connection between the module and the inverter should be made via suitable PV mounting accessory cables with IP67 protection. These cables are dust-tight and water-protected, ensuring that no water penetrates the plug connections even in rain or when mounted outdoors. Additionally, UV-resistant sheath material is important, as silicone or special plastic coverings protect the cables from sun exposure and weathering.
Cable Routing and Protection
Route cables as short as possible and without loops to minimize line losses. Protect the cables from mechanical damage caused by edges or sharp edges with cable clamps and cable ducts. In many cases, you will find these components in the balcony power plant accessories section with suitable guide rails and clamps.
Recommended Mounting and Accessory Kits
In the area of balcony power plant accessories, there are various sets suitable for 600- and 800-watt systems.
Balcony power plant mount for flat roof, garden & ground: Stable aluminum construction with pre-drilled holes and sufficient connection options for 1–2 modules.
MiniRail sets with end clamps: Rails for trapezoidal sheet metal roofs or free-standing installations, suitable for common 60-watt panels.
Inverter mounts and cable mounts in the PV mounting accessory section: Brackets that securely position the inverter on the wall or near the socket.
For balcony power plant installation instructions, you will usually find illustrated guides that show step-by-step how to mount the bracket, secure the modules, and route the cables.

Zero feed-in means that a balcony power plant with storage does not feed excess solar power into the public grid, but instead uses it entirely within the household or stores it in a battery. The regulation ensures that the generated electricity is either consumed directly or temporarily stored in a battery storage system such as the Sunlit balcony power plant storage. In many households, this can significantly increase self-consumption and reduce grid feed-in to almost zero.
What is zero feed-in for balcony power plants?
Zero feed-in for balcony power plants means that the mini-PV system is regulated in such a way that no uncontrolled feed-in into the public grid occurs. Instead, the self-generated solar power is either used directly in the household or buffered in a battery storage system. Surpluses are not given away but are managed specifically.
For many users, zero feed-in is more economical than open feed-in into the grid, because the remunerated feed-in tariffs are often significantly lower than the current electricity price. In addition, zero feed-in systems often avoid bureaucracy and additional feed-in contracts, which makes the use of balcony power plants with storage particularly attractive.
Why store instead of feed in?
A balcony power plant with storage, such as a Sunlit balcony power plant storage, focuses on self-consumption rather than feeding into the grid. The generated solar energy is first fed into the household load; if there is still power left, it is charged into the battery storage.
The main advantages are:
Higher self-sufficiency through the use of self-generated electricity even in the evening hours.
Reduced grid load and more stable operation of the local power grid.
Less dependence on rising electricity prices, as a larger part of consumption is covered by your own solar electricity balance.
Zero feed-in technology: sensor technology and measurement
The basis for zero feed-in is the measurement of current household consumption. For this purpose, current transformers (CT sensors) or an external smart meter are used at the electricity meter or in the house distribution, which record the energy flow in real time.
These sensors measure:
Current flow per phase.
Direction of energy flow (grid consumption or grid feed-in).
Instantaneous power in watts and integrated energy quantity in kilowatt hours.
The measured values are passed on to the inverter or an energy management system, which then dynamically adjusts the output of the balcony power plant or the storage unit.
Smart meter, bidirectional meter and balcony power plant
A new bidirectional meter records both electricity consumption and feed-in separately and is the basis for transparent and legally compliant accounting. Combined with a smart meter gateway, an intelligent metering system is created that transmits real-time data to the grid operator, but also to energy management systems.
For balcony power plants with storage, it is crucial that the measured values are available quickly enough to regulate the PV power in fractions of a second. Many systems therefore also use their own energy meter or a local measuring device that communicates directly with the inverter, while the official smart meter is primarily responsible for billing and grid monitoring.
Sunlit storage and dynamic feed-in
Sunlit balcony power plant storage systems use dynamic feed-in control that is based on the grid flow. Measurement at the grid connection point (e.g. via a smart meter or a balcony power plant energy meter) shows whether the household is currently drawing electricity or whether there is a surplus.
The inverter adjusts its output power so that the net flow at the electricity meter is as close to zero as possible. If consumption increases, the storage unit can increase its discharge power or the PV power; if consumption decreases, the feed-in power is throttled or the storage unit is charged without surplus flowing into the grid.
How does the Sunlit storage communicate with the electricity meter?
Communication between the Sunlit balcony power plant storage and the electricity meter takes place via standardized protocols such as Modbus or other energy management interfaces. Typically, measured values (e.g. current power, grid consumption/feed-in) are read from the smart meter or an additional energy meter and transmitted to the inverter or energy management system.
Depending on the system architecture, transmission can take place via WLAN, Ethernet or bus-based connections. The Sunlit or manufacturer app then displays generation, consumption, storage level and the current grid feed-in or net savings effect in real time, so that the user can transparently track the zero feed-in.
The role of smart plugs and smart consumers
Smart plugs and other intelligent household appliances can be integrated into the zero feed-in logic to further optimize self-consumption. They enable load management, where appliances such as washing machines, tumble dryers or heat pumps are operated when the Sunlit storage or the balcony power plant provides sufficient power.
Loads shifted in this way can significantly reduce the required grid consumption and at the same time increase the battery's utilization. The combination of smart meter, storage and smart plugs forms a small energy management system that is interesting for both homeowners and tenants.
Market trends: balcony power plant storage and zero export
In the market for balcony power plants with storage, the demand for zero feed-in and zero-export solutions is constantly growing. Rising electricity prices, convenient plug-and-play systems and the widespread expansion of smart meters are driving acceptance.
Typical user profiles are:
Tenants in city apartments with a south-facing balcony.
Homeowners with a small terrace or balcony system.
Small businesses or charging stations that want to increase their self-sufficiency.
At the same time, grid operators are developing increasingly strict regulations for feed-in power, which makes systems with zero feed-in and dynamic feed-in control increasingly attractive.

Sample calculations from some expert sources show that households with balcony power plants and storage can save several hundred euros in electricity costs annually, depending on location and consumption profile. The exact values depend on the area, orientation, consumer behavior, and tariffs.
Important Questions on Zero Export
What is zero export for a balcony power plant?Zero export means that the balcony power plant or storage unit is controlled so that the generated solar power is fully used or stored within the household, without uncontrolled surpluses flowing into the public grid.
How is zero export technically implemented?Current flows at the grid connection are measured via energy meters or smart meters. The inverter or energy management system adjusts the PV output or storage discharge in real time, so that the net feed-in flow is reduced to zero or near zero.
Is zero export allowed everywhere?Zero export is generally technically possible but must be adapted to the respective grid operator regulations and specifications for maximum feed-in power. In many regions, newer bidirectional meters and smart meters explicitly support this mode of operation.
Do I need a smart meter for zero export?An official smart meter is not mandatory, but very helpful. Often, a suitable smart counter or a balcony power plant energy meter that communicates directly with the inverter or storage unit is sufficient.
How does zero export affect subsidies and remuneration?Since little to no electricity flows into the grid with zero export, feed-in tariffs usually do not apply. In return, self-consumption increases, so the financial benefit results more from the reduction in the amount of electricity purchased.
Future Trends: Balcony Power Plant, Storage, and Smart Meter
In the long term, the spread of balcony power plants with storage and zero export will continue to increase, especially in urban areas with high rental rates. The combination of smart meters, balcony power plants, and intelligent energy management will increasingly become the standard solution for tenants and homeowners.
Furthermore, stronger integration of wall boxes, heat pumps, and other electrical consumers into this system is planned, so that balcony power plant storage will not only enable self-consumption but also cost-optimized charging and peak shaving.
Buying Guide: Zero Export and System Choice
When purchasing a balcony power plant with storage for zero export, you should pay attention to the following points:
Compatibility of the inverter or storage with zero export and dynamic feed-in control.
Support for smart meters or local energy meters for real-time measurement.
Availability of an app for controlling operating modes (self-consumption, zero export, valley charging).
Sufficient storage capacity for your typical consumption (e.g., LiFePO4 storage with 3–5 kWh).
Looking at reviews and tests of models like Sunlit balcony power plant storage, Shelly 3EM, or Anker SOLIX systems can also help you find the right solution for your apartment or house.

Modern balcony power plants convert solar energy on the balcony or terrace directly into usable household electricity. A central component in this process is the microinverter, which converts the DC voltage from the modules into grid-compliant AC power. Anyone planning to build a system with more power or better expansion prospects today will increasingly encounter models with 2000 watts of power – for example, from Hoymiles or Deye. These devices not only offer greater power reserves but also higher flexibility and more modern monitoring options.
Market Trends and Legal Background
The market for balcony power plants in Germany is growing strongly, boosted by lower electricity prices, rising energy costs, and the federal government's "Solar Package 1". According to current legislation, balcony power plants have a maximum feed-in power of 600 watts, which is expected to be increased to 800 watts in the future. This makes the use of microinverters with 2000 watts attractive, as they can fully utilize the modules while the feed-in is limited by software to the prescribed maximum power.
In this environment, DRBO Greenenergy positions itself as a provider of high-quality solar and energy storage solutions for private customers, specialist retailers, and installation companies. The company already supplies numerous hardware stores and electrical retailers with balcony power plants, solar modules, microinverters, and suitable accessories such as mounting brackets and energy management systems. With a focus on quality, sustainability, and practical plug-and-play solutions, DRBO Greenenergy aims to drive the decentralized energy transition and make clean energy accessible to tenants as well as homeowners.
Why 2000W Microinverters?
Compared to classic 600-watt or 800-watt transmitters, a 2000-watt microinverter offers clear advantages: It processes the maximum power of strong modules better, reduces losses at high solar radiation values, and allows for greater expansion flexibility. Typical 2000-watt devices like the Hoymiles HMS-2000-4T or the Hoymiles HMT-2000-4T can supply up to four modules with high currents per input, which is particularly beneficial for modern 550-watt or 600-watt panels with 16 amps or more.
Furthermore, a 2000-watt device offers better future-proofing if the legal limits for balcony power plants continue to increase or if they want to couple them with decentralized storage solutions via bidirectional storage in the future. Even with partial shading or different module orientations, you benefit from more channels and separate MPPT trackers that finely optimize the performance per module. This combination of higher gross system performance and intelligent control makes upgrading to a 2000-watt microinverter worthwhile for many households.
2000W Microinverter Comparison: Hoymiles vs. Deye
For balcony applications, manufacturers such as Hoymiles and Deye are particularly in focus. Hoymiles offers the HMS-2000-4T, a single-phase microinverter with up to 2000 watts of AC output power and four separate MPPT inputs, designed for four modules and supporting up to 16 amps per input. Alternatively, the HMT-2000-4T is available as a three-phase variant, which distributes the power across all three phases and is particularly suitable for three-phase household connections.
Deye positions itself with microinverters for decentralized and compact inverter solutions that can be easily integrated into balcony power plants and smaller PV systems. Deye devices combine high efficiency with modern communication and are compatible with plug-and-play systems that you connect via a Schuko plug or directly to the house grid. Both brands support efficient feed-in while simultaneously limiting to the legally permitted 600 or 800 watts, making a 2000-watt microinverter suitable for both current and future standards.
Balcony Power Plant Upgrade: Performance and Safety
An upgrade to a 2000-watt microinverter is sensible if you want to use more than two strong modules now or in the near future, or if you are planning for significant expansion. Typical balcony power plants with 800-watt devices are already operating at the maximum permissible feed-in power – a 2000-watt inverter can process this peak power as needed and limit the feed-in to the prescribed limit via software.
It is important that module voltage, module current, and grid connection exactly match the manufacturer's datasheets. Most 2000-watt microinverters require a minimum switch-on voltage (often around 22 volts) and a maximum operating current per input, which must not be exceeded. In addition, the wiring and the circuit breaker in the house grid should comply with the higher power requirements and VDE standards. Incorrect installation poses a fire and safety risk, which is why professional planning or installation by an electrician is recommended.
Software Limitation to 800W for Germany
In Germany, the maximum feed-in power for balcony power plants is limited to 600 watts, to be increased to 800 watts in the future. A 2000-watt microinverter can implement this regulation via an integrated software or grid profile setting: Using the DTU communication button (e.g., Hoymiles WLite), you can limit the maximum output power to 800 watts or below. This is done by adjusting the grid profile or the feed-in limit in the manufacturer's portal, without needing to change the hardware itself.
The throttling is not only legally required but also protects the house grid and other devices from overloads. Modern 2000-watt devices show in monitoring how much power is actually fed in and document that the limits are being observed. For SMEs and private users, this means: You can install a powerful system and later adapt it flexibly if the legal framework changes or the demand for self-consumption increases.
Accessories: AC Cables, End Caps, and Communication
For the safe operation of a 2000-watt microinverter on a balcony power plant, you need suitable accessories. These primarily include AC cables of appropriate cross-sectional size (often 1.5 or 2.5 mm² depending on length and load), which are connected to Schuko plugs or directly to the house connection line. For many Hoymiles models, special AC Trunk sets with T-connectors and protective caps are available, enabling clean and maintenance-friendly wiring.
In addition, end caps and connectors (e.g., Field Connector) are important to seal the DC side and ensure touch protection. Communication and monitoring are carried out via a DTU (e.g., Hoymiles-DTU WLite), which is connected to the microinverter or the house system and allows you to observe power, energy meters, and status via an app or web platform. With these components – AC cables, end caps, DTU, and possibly mounting brackets – a balcony power plant with a 2000-watt microinverter is fully and safely installed.
Practical Applications and ROI
A typical application for a 2000-watt microinverter is an east-west system on a balcony with two or four high-performance modules. Under ideal conditions, such a system can briefly generate well over 800 watts, with the inverter limiting the feed-in to the legally permissible limit. The remaining power can then be used via a balcony hybrid inverter or a bidirectional energy storage system to store electricity or shift loads in time.
For households with high basic consumption, a 2000-watt system can significantly increase the self-consumption rate, so that less electricity needs to be drawn from the grid. The amortization depends on local electricity prices, feed-in times, and usage, but many operators achieve an attractive return on investment once the system runs stably for several years. Especially with long-term use, you benefit from the higher power reserve and better expandability if you integrate additional modules or storage.
Important Purchase Advice and Installation
When purchasing a 2000-watt microinverter, you should pay attention to several points: manufacturer, warranty period, IP protection class, compatibility with your modules, and the available DTU solution. Models such as the Hoymiles HMS-2000-4T or the HMT-2000-4T have high efficiencies, multiple MPPT trackers, and a robust metal housing construction, which makes them particularly suitable for balcony use.
For installation, you need a stable mounting system that securely fixes the PV modules and safely absorbs mechanical loads (wind, snow, stress). Electrical installation should ideally be carried out by an electrician with expertise in photovoltaics to ensure compliance with VDE standards and fire protection. In addition, you should register your system with the grid operator and, if applicable, the energy supplier in good time to correctly utilize feed-in tariffs or refunds.

An 800W balcony power plant combined with a 3kWh solar storage and bidirectional inverter maximizes self-consumption and minimizes electricity costs. This configuration solves typical challenges such as low solar irradiation and enables future-proof applications.
Market Trends for Balcony Power Plants
The market for balcony power plants is growing rapidly, as more and more tenants and homeowners want to become independent from fossil fuels. According to current reports, over 500,000 households in Germany are installing such systems, with a focus on storage extensions up to 3kWh. Calculating balcony power plant yield is one of the most common requests, as users want to accurately forecast savings.
The integration of 3kWh solar storage systems is increasing by 40 percent annually, driven by rising electricity prices of around 0.30 Euros per kWh. Bidirectional inverters are gaining popularity as they offer preparation for V2H systems. In Southern Germany, optimized systems achieve yields of up to 900 kWh annually.
At DRBO Greenenergy, we pursue a clear goal: to drive the decentralized energy transition together with our customers. We already supply numerous hardware stores, specialized dealers, and installation companies with high-quality solar and energy storage solutions and now also support private customers with customized plug-and-play systems.
Calculate Annual Yield and Savings
An 800W balcony power plant generates an average of 700 to 900 kWh of electricity annually, depending on location and orientation. With a 3kWh solar storage, self-consumption increases to 80 to 90 percent, which allows for savings of 200 to 270 Euros annually at 0.30 Euros per kWh. Without storage, much energy dissipates into the grid, but the 3kW storage buffers surplus for evening hours.
Calculating balcony power plant yield shows: In Central Germany, 800 kWh is realistic, in sunny regions up to 900 kWh. Amortization occurs within 1.5 to 2.5 years. Users save in the long term through reduced grid purchases and increasing EEG feed-in tariffs.

Influence of Orientation on Yield
South-facing systems achieve the highest yield with up to 900 kWh annually. East-West orientations deliver 20 to 30 percent less, but are ideal for typical balcony locations. A tilt of 30 to 35 degrees optimizes irradiation, especially in winter.
With south orientation, the yield is 850 kWh, with purely east orientation only 650 kWh. Bifacial modules increase East-West yields by 10 to 15 percent. Regular cleaning avoids 5 to 10 percent losses due to dirt.

A 3kWh solar storage covers 2 to 3 days of cloud cover, with a consumption of 10 kWh daily. Surplus from sunny days is charged with priority. Bidirectional charging gets grid electricity cheaply at night if needed.
Without storage, the benefit on dull days drops to 20 percent, with storage to 80 percent. Apps predict consumption and charge automatically.
