A CT clamp (current transformer) measures the current flow in the main meter and regulates the inverter so that no surplus electricity from your balcony power plant storage is fed into the grid (Zero Export). Here's how to install it: attach the CT clamp to the main conductor, run the signal cable to the inverter, configure and test it in the app. This saves costs and complies with VDE standards – ideal for tenants and homeowners. Check: Balcony Power Plant Mounts & Installation Why is Zero Export with CT Clamp Essential for Balcony Power Plants? Zero Export prevents grid feeding by real-time measurement of current flow, complies with VDE-AR-N 4105, and protects against penalties. Without a CT clamp, uncontrolled feeding is a risk; with it, you save 30–40% on your electricity bill and optimally use dynamic tariffs like Tibber. With Zero Export Without Zero Export High self-sufficiency (up to 80%) Low self-sufficiency (approx. 30%) Savings €400–800/year Higher grid consumption No feed-in penalties Risk of warnings Optimal for storage Loss of surplus Zero export is particularly crucial for balcony power plants with storage, such as the SunEnergyXT BK215 PLUS from DRBO Greenenergy. It precisely measures household consumption and dynamically adjusts feed-in. Legally required in Germany, it avoids conflicts with grid operators. With dynamic tariffs like Tibber or aWATTar, the CT clamp maximizes self-consumption by charging the storage at favorable prices. Common errors without Zero Export: overproduction leads to unnecessary grid consumption or penalties. With a CT clamp, tenants and homeowners achieve full independence. What is a CT Clamp and How Exactly Does it Work? The CT clamp is a non-contact current transformer that measures the current flow on the main conductor and sends a signal to the inverter to adjust the power. Compatible with SunEnergyXT BK215 PLUS and Deye inverters from DRBO Greenenergy. The current transformer (CT) encloses the main conductor without contact and generates a proportional voltage signal. This is routed via a cable (up to 10 m) to the microinverter, e.g., Deye SUN-M80G4-EU-Q0. The inverter reduces the output power in real-time as soon as household consumption is covered. For balcony power plants with storage like the SunEnergyXT 500, the storage buffers surplus instead of feeding it in. Polarity is crucial: arrow direction towards the consumer. Works seamlessly with Shelly Pro 3EM for precise monitoring. What are the Requirements for Installation? You need a compatible storage unit like SunEnergyXT BK215 PLUS, Shelly Pro 3EM, tools (screwdriver, cable ties) and access to the meter box. For tenants: Plug-and-play with DRBO Greenenergy with 0% VAT. Requirements include a balcony power plant-compatible storage unit, e.g., the refurbished BK215 PLUS from DRBO Greenenergy (2.15 kWh, expandable up to 17.2 kWh). The CT clamp must match the inverter, such as the Deye SUN-M80G4-EU-Q0 with integrated Wi-Fi. Additionally: Shelly Pro 3EM for zero export and Home Assistant integration. Tool checklist: electrical tape, cable lugs, multimeter. For tenants without electrical knowledge, DRBO's complete sets like the Tenant Starter Set (€1,548) are suitable. Safety: switch off power, check RCD. If unsure, use DRBO's free consultation. How Do I Install the CT Clamp Step by Step? 1. Switch off power, attach CT clamp to main conductor (L1) in meter box. 2. Route signal cable to inverter (max. 10 m), check polarity. 3. Configure in app (SunEnergyXT or Shelly) and test with load. Check: Balcony Power Plant Shop Dr. Bo Step 1: Switch off RCD, open meter box, identify main conductor (L1, thickest cable). Open CT clamp and enclose it – arrow points towards consumer. Step 2: Lay 2-core signal cable (0.75 mm²), twisted pair recommended against interference. Connection at inverter: CT+ and CT- (see Deye SUN-M80G4-EU-Q0 manual). Step 3: Switch on power, open app (SunEnergyXT App iOS/Android), activate Zero Export, test polarity (consumption increases, feed-in decreases). Simulate load: switch on device, check feed-in.

What Role Does the Electricity Storage Play in Zero Export? The storage buffers surplus instead of feeding it in, e.g., SunEnergyXT 500 (5 kWh, 800 W) or BK215 PLUS (2.15 kWh). Charges during high consumption, discharges when needed – maximizes self-sufficiency. In a zero-export setup, the electricity storage plays a central role: the CT clamp signals surplus, and the inverter directs it to the storage (e.g., LiFePO4 cells in the SunEnergyXT BK215 PLUS). With SunEnergyXT 500 (5,024 Wh, 4 MPPT trackers) or 500 PRO (2,400 W), expandable up to 30 kWh with B500 modules. Bidirectional EV3600 enables charging/feeding. Advantages: no grid consumption during the day, emergency power (2,400 VA). DRBO Greenenergy offers refurbished BK215 for an affordable entry. Integration with Home Assistant for smart control.
