Is an 800-watt balcony power plant with battery storage worth it?

Article published at: Jan 14, 2026

An 800-watt balcony power plant with storage is an excellent way to reduce your energy costs and contribute to the energy transition. With an annual production of up to 800 kWh and a 2-5 kWh storage unit, users can increase their self-consumption to over 90%. Amortization occurs within 3-5 years, especially with an electricity price of 30 cents/kWh. DRBO Greenenergy offers suitable solutions for this.

How does an 800-watt balcony power plant with storage work?

An 800-watt balcony power plant consists of solar modules that convert sunlight into direct current. The micro-inverter converts this into 800 watts of alternating current, which is fed into the power grid. Excess electricity is temporarily stored in a battery, such as a LiFePO4 battery, and can be used again in the evening. A smart meter and an app automatically control the feed-in and storage, maximizing self-consumption. DRBO Greenenergy integrates high-quality SunLit storage solutions into their systems to ensure maximum efficiency.

Is an 800-watt balcony power plant with storage worth it?

Yes, the investment is worthwhile. With an annual yield of 800 kWh and self-consumption of over 90%, 250-350 € can be saved annually, with an electricity price of 30 cents/kWh. The amortization period is typically 3-5 years. Without storage, self-consumption is only 60-70%, meaning that with storage, savings increase by 30%. DRBO Greenenergy offers a cost-effective solution with its advanced SunLit storage units.

Which storage unit is suitable for an 800-watt balcony power plant?

The best storage units for an 800-watt balcony power plant are LiFePO4 batteries with a capacity of 2-5 kWh. These batteries offer a high cycle count (6000+), are temperature-resistant from -20 to +45 °C, and have a long service life. DRBO Greenenergy offers a flexible, expandable solution with its SunLit storage units, which are perfectly compatible with common inverters like Deye and Hoymiles.

Storage Model Capacity Price (approx.) Advantages
SunLit Basic 2 kWh €600 Plug & Play, expandable
Zendure SolarFlow 1.92 kWh €900 10-year warranty, app
Anker SOLIX 1.6 kWh €800 Modular up to 16 kWh
EcoFlow STREAM 3.84 kWh €1200 EPS Function

How to install an 800-watt balcony power plant with storage?

Installing a balcony power plant with storage is quick and easy. First, mount the solar modules on your balcony without screws. Then connect them to the inverter and the storage unit and plug everything into a Schuko socket. Use the app to set up the system and register it with the grid operator – all within an hour. No electrician is required. DRBO Greenenergy offers complete kits that include cables, mounts, and all necessary components.

Which is the best 800-watt balcony power plant with storage?

The best models feature bifacial solar modules (900+ Wp), 4-MPPT inverters, and a storage capacity of at least 2 kWh. DRBO Greenenergy offers systems with SunLit storage units that impress with their quality and value for money. These complete kits are ideal for tenants and homeowners who prioritize easy installation and high efficiency.

Can an 800-watt balcony power plant with storage be expanded?

Yes, an 800-watt balcony power plant can be easily expanded. Up to 2400 Wp of solar modules and 10+ kWh of storage can be integrated. DRBO Greenenergy offers expandable models such as the SunLit options for this purpose. An expansion increases the yield by 50-100%, but attention must be paid to grid operator limits and compatibility.
