Set up in 4 steps – install electricity meter, connect Wi-Fi, activate zero-export mode, pair inverter – it works perfectly with SunEnergyXT systems. Ideal for renters and homeowners who want to use solar power in compliance with regulations. Check: Solar energy systems for the garden What is the Shelly Pro 3EM and why do I need it for my balcony power plant? The Shelly Pro 3EM is a three-phase energy meter with integrated current transformers (CT63) for precise yield measurement and grid monitoring. Its core function is zero-export control: The system automatically limits your balcony power plant to zero grid feed-in – a legal requirement for safe feed-in up to the new 7,000 W power limit from 2026. The Shelly Pro 3EM works excellently with inverters like Deye and SunEnergyXT and offers local data processing without cloud dependency, ideal for data protection and stability. Feature Shelly Pro 3EM Standard Electricity Meter Real-time measurement Yes, every second Consumption only, no live data Zero-export control Yes, with API integration No WLAN connectivity Integrated No Home Assistant compatible Yes No Local data processing Yes Yes (but no control) DRBO Greenenergy Expert Views: The Shelly Pro 3EM is the heart of every modern balcony power plant setup at DRBO. We combine it with SunEnergyXT inverters into complete sets that are ready for immediate use – especially for tenants without an electrician visit. With the new 7,000 W power limit in 2026, intelligent measurement will become even more crucial. Our customers benefit from a Trustpilot rating of 4.6/5 and local German support that quickly resolves integration issues. What hardware and software do I need for setup? For setup, you need the following hardware: the Shelly Pro 3EM itself, three current transformers (CT63 models), a Wi-Fi router with a stable connection, a compatible inverter (e.g., SunEnergyXT 500/500 PRO with 800 W or 2,400 W output power), and a balcony power plant with 800–2,400 W nominal power. Software-wise, you use the free Shelly App for iOS and Android, optionally also Home Assistant or OpenHAB for advanced automation scenarios. The installation takes place directly at the house connection electricity meter or the sub-distribution – typically in 3–5 minutes with click-installation. DRBO Greenenergy Expert Views: DRBO offers refurbished Shelly complete sets with up to 40% savings compared to new goods. With our 0% financing via OpenBank, upgrading is often more affordable than expected. Many customers start with our 900 Wp balcony power plant set (€269.00, RRP €399.00) and later add a Shelly Pro 3EM and a SunEnergyXT storage unit – modular, budget-friendly, and future-proof. How do I install and connect the Shelly Pro 3EM step by step? Installation takes place in four clear steps: First, switch off the fuse, then route the three current transformers (CT63) around the phase conductors L1, L2, and L3 and connect all terminals correctly. In the second step, switch on the Shelly device, scan the QR code or manually connect to your home Wi-Fi. Thirdly, activate the Zero-Export mode in the Shelly App (Menu: Devices → Shelly Pro 3EM → Power Limit). Finally, set the maximum power to zero to guarantee complete zero export. DRBO Greenenergy recommends all customers to go through these steps with the consulting team – free consultation can be booked at https://drbogreeninergy.com/pages/kostenlose-beratung-fur-solalosungen-drbo-greenenergy. How do I connect the Shelly Pro 3EM to my inverter for dynamic control? Pairing is done via API integration: The Shelly Pro 3EM continuously sends performance data to your inverter (e.g., SunEnergyXT models) via Modbus-TCP or MQTT – typically with Home Assistant as an intermediary. This zero-export loop works as follows: The inverter automatically throttles its solar yield when household consumption drops, to avoid any grid feed-in. This is perfectly prepared for the new 7,000 W power limit in 2026. Optionally, the system can also be combined with dynamic electricity tariffs (Tibber, aWATTar) – here, the storage charges automatically during low prices, while zero export is guaranteed during peak loads. Before live operation, you should run a short test scenario to check control reliability and switching frequency. DRBO Greenenergy Expert Views: The technical team at DRBO Greenenergy has implemented over 500 such integrations and knows every peculiarity of SunEnergyXT, Deye, and APsystems inverters. Our free consultation helps with problems – including Home Assistant setup for power users. Many customers use our Tenant Starter Set (€1,548.00, RRP €1,798.00) or the Dynamic Starter PLUS Set (€3,199.00) with pre-configured Shelly Pro 3EM integration for Tibber/aWATTar tariffs. This saves weeks of trial-and-error. What common errors and error messages can occur? The most common error is "Current transformer not detected" – here you should check the CT63 connection and ensure that the phases are correctly assigned (L1→CT1, L2→CT2, L3→CT3). Errors such as "Zero Export active, but grid feed-in detected" indicate a missing inverter communication – validate the Modbus/MQTT connection and shorten the polling interval to less than 100 ms. If the app shows "Zero yield despite sunshine", check the Wi-Fi connection, restart the Shelly, and update the firmware. For dynamic tariff errors ("Price increase not detected"), validate your Tibber/aWATTar API token and synchronize the local time of the Shelly device. Check: Solving Marstek B2500 problems effectively and reliably Error Message Cause Solution Current transformer not detected CT63 incorrectly connected or phase inverted Check CT connections, correctly assign phases L1–L3 Zero Export active, but feed-in detected Inverter API not connected Test Modbus/MQTT, polling interval <100 ms Zero yield with sun WLAN connection interrupted or firmware outdated Check router proximity, restart Shelly, update firmware Dynamic tariff not detected API token invalid or time not synchronized Renew API token in app, synchronize NTP time How do I use the Shelly Pro 3EM for yield measurement and monitoring? The Shelly App offers real-time monitoring: You can see live yield, daily yield, and monthly totals clearly on a dashboard. For extended metrics (e.g., CO₂ savings, storage cycles), integrate the device with Home Assistant – ideal for B2B reporting and warranty documentation. The Shelly Pro 3EM enables CSV data export for maintenance logs, which is particularly important for lease agreements or insurance matters. You can also set up notifications: alarms for anomalies (e.g., sudden power drop) help to detect module defects early and minimize yield losses. How do I save with Shelly Pro 3EM and dynamic electricity tariffs? Dynamic electricity tariffs (Tibber, aWATTar) reduce your electricity price by up to 50% in off-peak phases – the Shelly Pro 3EM automatically triggers battery charging at the cheapest times. The new 2026 rule (7,000 W power limit) is a game-changer: The Shelly Pro 3EM remains compatible without a hardware upgrade and becomes even more relevant for higher capacities. The combination of a balcony power plant (zero export via Shelly), energy storage (intelligent, tariff-controlled charging), and optionally a smart heat pump (dynamic load shifting) can save up to 40% of your energy costs.

DRBO's Tenant Starter Set was specifically designed for this. With our 0% financing, upgrading becomes budgetable – on average, customers pay off the system in 4–5 years through saved electricity costs. What legal and safety aspects do I need to consider? Zero export is not an option, but an obligation: electricity must not be fed into the public grid without permission. The Shelly Pro 3EM with zero-export configuration complies with all VDE guidelines and enables safe, legal feed-in. The measuring accuracy of the Shelly Pro 3EM is ±2% – sufficient for monitoring and self-consumption optimization, but not for official electricity billing. Data protection is a plus: local storage without mandatory cloud upload makes the system GDPR-compliant and is particularly valued by tenants. Document your setup with photos and videos – this is important for liability issues or warranty claims. DRBO Greenenergy supplies all systems with a TÜV test report, so you are legally covered. Frequently Asked Questions Is the Shelly Pro 3EM also suitable for rental apartments? Yes, but with limitations. The Shelly Pro 3EM must be installed at the main meter – in rental apartments, this is often not accessible. DRBO offers special tenant alternative sets with compact pre-connected Shelly boxes that work without a sub-distribution and are usually approved by landlords. Use the free consultation to find the best solution for your situation. Which inverters are compatible with Shelly Pro 3EM? Tested and recommended are SunEnergyXT models (BK215 PLUS, 500 series with 800 W or 2,400 W, EV3600), as well as Deye and APsystems inverters. In general, the Shelly Pro 3EM works with all devices that offer Modbus-TCP or MQTT-APIs. DRBO comprehensively tests all these integrations before sale. How much electricity does Shelly Pro 3EM + Zero Export really save? Zero export itself does not save electricity – it only prevents illegal grid feed-in. Real savings come from self-consumption optimization: With monitoring + dynamic load control, customers typically achieve 15–40% additional self-sufficiency. DRBO documents these values in customer projects. Do I need an electrician for installation? Conditionally. The current transformer installation at the meter box often requires a specialist, as energy supply companies have specific requirements. DRBO arranges local partners or offers package services with installation – ask during the free consultation. Will Shelly Pro 3EM still be relevant after 2026? Yes. The new 7,000 W power limit in 2026 does not change the measurement and control logic – the Shelly Pro 3EM becomes even more relevant due to the higher power.

A Smart Meter for a balcony power plant is an intelligent digital electricity meter that records real-time measurement data and enables bidirectional communication with storage systems, inverters, and grid operators. Unlike classic bidirectional meters, a Smart Meter offers app control, zero export via external controllers like the Shelly Pro 3EM, and optimization of dynamic electricity tariffs (Tibber, aWATTar). The result: maximum cost savings, grid-friendly feed-in, and 2026 compliance for tenants and homeowners. Check: Full-Black Solar Modules & Accessories What exactly is a Smart Meter for a balcony power plant? A Smart Meter is a digital electricity meter that – unlike analog or simple digital meters – continuously records consumption, self-generation, and grid feed-in in real time and transmits this data via radio (GPRS, LTE, PLC) to your grid operator. For balcony power plants, the Smart Meter acts as a central communication interface between your solar system, any possible storage system, and the electricity grid. While a classic meter only turns mechanically forwards or backward, a Smart Meter offers intelligent API interfaces for home automation and enables precise control of electricity flows – ideal for the decentralized energy transition. How does a Smart Meter differ from a classic bidirectional meter? A bidirectional meter mechanically records consumption and feed-in and stores the data on a time basis – without real-time feedback. A Smart Meter, on the other hand, communicates live: the meter sends measurements to your controller, storage, and cloud app every 15 minutes (or second by second upon request). This enables automatic zero export, dynamic tariff optimization, and remote control – functions that a bidirectional meter technically does not offer. For balcony power plants with battery storage systems such as the SunEnergyXT BK215 PLUS, a Smart Meter is therefore significantly more efficient. Which communication protocols does a Smart Meter use? Smart meters typically use three communication methods: Powerline Communication (PLC) via the power line itself, GPRS/LTE via the mobile network, or WLAN/Ethernet in modern installations. PLC is cost-effective and requires no additional cabling; GPRS/LTE offers range and security; WLAN enables local API integration with Home-Assistant or the SunEnergyXT App. The advantage: your balcony power plant system receives second-by-second updated meter data and can automatically adjust the output power or storage charge – crucial for zero export and intelligent tariff use. What are the advantages of a Smart Meter for balcony power plants? Zero Export: The Smart Meter reports surplus production, an external controller (e.g., Shelly Pro 3EM) sends the signal to your inverter, which immediately throttles down – no manual switching required. Dynamic Tariffs: With Tibber or aWATTar, you receive new electricity prices hourly. Your Smart Meter + storage system automatically charges at low prices, discharges at high prices (e.g., 6:00 PM–9:00 PM at €0.40–€0.60/kWh) – up to 20–40% cost savings possible. Real-time Monitoring: App access to every production value and every grid feed-in. Storage Synergy: Intelligent batteries like the SunEnergyXT BK215 PLUS coordinate with Smart Meter data for optimal self-sufficiency. 2026 Compliance: New grid guidelines require zero export in many regions – Smart Meters make this future-proof. When will a Smart Meter become mandatory for balcony power plants? Legally, a Smart Meter is not mandatory for balcony power plants until 2026. However, the Smart Meter rollout by grid operators will be successively expanded between 2025–2030, and many grid operators will require zero export for new installations from 2026 – which is much easier to implement with a Smart Meter. For tenants who use dynamic tariffs or live in grid-congested regions, a Smart Meter is already recommended today and quickly pays for itself through cost savings. What are the installation requirements for a Smart Meter? Before installing a Smart Meter, the following points should be met: Grid Operator Registration: Your balcony power plant must be registered with the grid operator – a Smart Meter is often only installed after this registration. Compatible Devices: Storage systems (e.g., SunEnergyXT BK215 PLUS, SunEnergyXT 500 series), microinverters (Deye SUN-M80G4-EU-Q0, APsystems EZ1-M), and external controllers (Shelly Pro 3EM for zero export) must be API-compatible. Network Connection: WLAN or Ethernet for communication between the meter and storage/app. Electrician Check: While plug-and-play installation is often not the case, a specialist should check the grid connection and safety. Rollout Status: Check if your grid operator already offers Smart Meters in your district. DRBO Greenenergy Expert Views “At DRBO Greenenergy, we support our customers from the very beginning: Our free consultations clarify whether a Smart Meter makes sense for your situation and which components are optimally compatible. With our pre-configured Smart Meter sets – e.g., the SunEnergyXT BK215 PLUS (€749) with a compatible inverter – or refurbished storage solutions starting from €600, we enable cost-conscious tenants and homeowners to enter intelligent solar use. Our local German support team assists with registration with the grid operator, integration of Shelly controllers, and optimization of dynamic tariffs. With Trustpilot 4.6/5 and 0% financing via OpenBank, the path to 2026-compliant zero export is simple and affordable." How does zero export work with a Smart Meter? Zero export means your balcony power plant feeds no or minimal electricity into the public grid. With a Smart Meter, the process is fully automatic: the meter continuously records the electricity flow. If your solar system produces more than you consume, the Smart Meter reports this surplus to an external controller (e.g., Shelly Pro 3EM, €80–€150). The controller immediately sends the signal to your microinverter (e.g., Deye SUN-M80G4-EU-Q0, €79.90), which then automatically reduces its output power – ideally to zero. At the same time, you optionally charge your battery storage (e.g., SunEnergyXT BK215 PLUS or refurbished Minjet storage) with the surplus instead of feeding it into the grid. This is grid-friendly, avoids blocking by grid operators, and maximizes your return through self-consumption. Check: Watt to Amps Conversion Guide Can I combine dynamic electricity tariffs with a Smart Meter and a balcony power plant? Yes, absolutely – and this is one of the most valuable applications. With services like Tibber or aWATTar, your Smart Meter sends live production data to the app. At the same time, you receive hourly updated electricity prices. Your storage system (e.g., SunEnergyXT BK215 PLUS or B500) automatically charges at prices below €0.10/kWh and discharges during expensive hours (e.g., 6:00 PM–9:00 PM at €0.40–€0.60/kWh). Home-Assistant or the SunEnergyXT App even enable manual optimization, e.g., charging storage overnight at low prices. Realistic annual savings: €300–€500 with a combined setup of Smart Meter + 10 kWh storage + dynamic tariff. Scenario Storage Size Storage System Dynamic Tariff Estimated Annual Savings Tenant without roof (balcony) 2–4 kWh SunEnergyXT BK215 PLUS (€749) Tibber/aWATTar €150–€250 Tenant with terrace 4–6 kWh BK215 + B215 PLUS (€1,448) Tibber/aWATTar €250–€400 Homeowner with roof 10+ kWh SunEnergyXT 500 (€1,299) + B500 Modules Tibber/aWATTar €400–€600 Homeowner, cost-conscious 4–6 kWh Refurbished Minjet (€600) Tibber/aWATTar €200–€350 What are common mistakes during Smart Meter installation for balcony power plants? Mistake 1 – Self-installation of the Smart Meter: Many owners try to install the Smart Meter themselves. This is illegal and leads to loss of warranty, grid disconnection, or fines – always let the grid operator handle this. Mistake 2 – Incompatible Components: A used storage unit + any inverter will not automatically work with your Smart Meter. DRBO Greenenergy tests all combinations; check compatibility before purchasing. Mistake 3 – Zero Export without Calibration: A correctly calibrated controller is crucial – too aggressive throttling leads to yield losses, too weak to grid surplus. Mistake 4 – Ignoring Dynamic Tariffs: Many owners have a Smart Meter but do not use tariff optimization – cost savings are lost. Mistake 5 – Overlooking Local Rollout: Sometimes the Smart Meter is installed but cannot yet be activated. Check the status with your grid operator. Is a Smart Meter also suitable for tenants in rental apartments? Yes, and especially recommended – with one important prerequisite. For rental apartments with a balcony or terrace, a Smart Meter is ideal, as external controllers (e.g., Shelly Pro 3EM) function completely plug-and-play and do not require an electrician. DRBO Greenenergy offers specialized tenant starter kits, e.g., the 1800 Wp complete set starting from €449, which is already Smart Meter compatible.

Zero export for balcony power plants means the inverter precisely adjusts solar power to your household consumption, so no electricity flows into the grid. A CT clamp measures consumption wirelessly. Advantages: no bidirectional meter needed, no grid feed-in fees, ideal for renters. DRBO Greenenergy offers compatible complete sets with SunEnergyXT and Shelly Pro 3EM. Check: Dr. Bo Green Energy Product Range What is zero export for balcony power plants? Zero export ensures that your balcony power plant only feeds in as much electricity as is consumed in the household – surplus does not flow into the grid. Unlike standard feed-in systems with remuneration, everything is for self-consumption. Legally: 0% VAT for private individuals, simple registration with the grid operator. Ideal for renters, homeowners, and dynamic tariff users like Tibber or aWATTar. How does a CT clamp work with zero export? The CT (Current Transformer) clamp measures electricity consumption non-invasively on the phase cable in the distribution box, without interrupting the installation. It sends real-time data to the inverter, which adjusts the feed-in in 1-2 seconds. Compatible with SunEnergyXT 500 series and Shelly Pro 3EM for precise control and storage integration. CT Clamp Type Phases Compatible Inverters Example at DRBO Shelly Pro 3EM 1-3 Phases SunEnergyXT 500 / 500 PRO Compatible with BK215 PLUS Standard CT 1 Phase Deye SUN-M80G4-EU-Q0 In Renter Starter Set Extended CT 3 Phases APsystems EZ1-M Dynamic Starter PLUS What advantages does zero export offer for balcony power plant owners?

Bi-directional meters communicate with balcony power plant inverters via standardized protocols such as Modbus/RTU and local APIs. Communication typically occurs via an RS485 interface or smart meter gateways, enabling the inverter to record feed-in data in real time and dynamically adjust power production – for example, for zero feed-in or dynamic tariffs such as Tibber and aWATTar. With modern solutions like the Shelly Pro 3EM and SunEnergyXT inverters, this integration is becoming increasingly Plug & Play. Check: Balcony Solar Sets with Storage What is a bi-directional meter and why is it relevant for balcony power plants? A bi-directional meter measures electricity flow in both directions – generation and consumption – unlike one-way meters, which only record consumption. It is essential for zero feed-in, where surplus solar power does not flow into the grid, and for dynamic tariffs. From 2026, DIN VDE V 0126-95 mandates bi-directional communication to ensure grid stability. DRBO Greenenergy recommends refurbished storage units such as the BK215 PLUS in combination with modern meters as an ideal setup for tenants, as these systems are seamlessly integrated and achieve high self-consumption rates. Which interfaces connect meters and inverters? The most common interfaces are Modbus/RTU via RS485 for direct, robust connections, Ethernet with local APIs for smart integrations, and smart meter gateways according to the SMGW directive. The Shelly Pro 3EM serves as a flexible WLAN bridge and is compatible with SunEnergyXT products such as the BK215 PLUS. Interface Protocol Latency Suitable for balcony power plant?

What data is transmitted between the meter and the inverter? Real-time values such as active and reactive power (P, Q), cumulative feed-in and consumption values in kWh, voltage, and frequency for grid protection are transmitted. This data enables precise control, e.g., for zero feed-in or tariff optimization with Tibber and aWATTar. A typical data flow: The meter records grid data, transmits it via a bridge like Shelly Pro 3EM to the inverter (e.g., EV3600), which adjusts the feed-in and charges storage units like BK215 PLUS. How does dynamic feed-in management work with bi-directional meters? The inverter receives meter data in real time and automatically reduces feed-in, e.g., to zero for zero feed-in. Via Home Assistant or APIs, it optimizes charging cycles for storage units and adapts to dynamic tariffs to charge at favorable prices – up to 90% self-consumption is possible. DRBO Greenenergy pre-configures the Dynamic Starter PLUS Set for Tibber/aWATTar, ideal for the 2026 standards. Which protocols and standards govern communication? Modbus RTU/TCP (IEC 61158) is the de facto standard for solar systems, DLMS/COSEM the EU smart meter standard. JSON-REST APIs offer modern local alternatives, such as with Deye inverters. DIN VDE V 0126-95 requires secure data transmission for island grids from 2026. Which inverters and storage units are compatible with bi-directional meters? SunEnergyXT products such as BK215 PLUS (Modbus/RTU), 500 series (Ethernet/API), and EV3600 are excellently compatible. Deye inverters (e.g., SUN-M80G4-EU-Q0) offer precise control via Modbus. Refurbished storage units from DRBO Greenenergy are tested and Shelly Pro 3EM-compatible.
