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.

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?
Zero export saves costs: No bidirectional meter (up to €100/year), no grid fees, higher self-consumption rate up to 90%. Legally secure in restrictive regions, tenant-friendly without landlord approval. DRBO Greenenergy Refurbished sets like BK215 PLUS make it affordable and plug-and-play.
How to set up zero export for a balcony power plant?
Step 1: Choose compatible hardware like SunEnergyXT 500 (800 W) with Shelly Pro 3EM. Step 2: Clip CT clamp to the main distribution board, connect inverter via Wi-Fi. Step 3: Configure app, register with grid operator, test. DRBO Greenenergy sets are pre-calibrated, German support team helps for free.

When is zero export worthwhile – and when not?
Worthwhile for renters with a balcony, households with 40-60% self-consumption, and dynamic tariffs. Less so for small consumptions under 2,000 kWh/year or large rooftop systems with remuneration. Break-even at €900-€1,200 investment in 5-7 years, optimized by 0% financing at DRBO Greenenergy.
Which inverters and storage systems support zero export?
SunEnergyXT BK215 PLUS (2.15 kWh, expandable up to 17.2 kWh), 500 series (5 kWh, 800/2,400 W), EV3600 with bidirectional operation. Compatible with Deye SUN-M80G4-EU-Q0 (800 W, IP67) and APsystems EZ1-M. DRBO complete sets like the Renter Starter (1,548 €) integrate everything.
| Inverter | Power | Storage Compatibility | Price (DRBO) |
|---|---|---|---|
| SunEnergyXT 500 | 800 W On-Grid | Up to 30 kWh (5x B500) | €1,299 |
| Deye SUN-M80G4-EU-Q0 | 800 W | BK215 PLUS | €79.90 |
| APsystems EZ1-M | 800 W | BK215 PLUS | €104.90 |
What are the legal frameworks for zero export?
The Federal Network Agency requires registration; for >800 W, a bidirectional meter is often required – zero export bypasses this. 0% VAT under 25 kW, grid operators tolerate CT standards. Insurance covers it, renters often don't need approval for zero export. DRBO advises on country-specific rules.
Can zero export be combined with dynamic electricity tariffs?
Yes, perfect for Tibber/aWATTar: CT clamp optimizes feed-in at favorable prices, storage charges during lows. Up to 50% cost savings. DRBO Dynamic Starter PLUS Set (€3,199) is optimized for this, with SunEnergyXT 500 and 0% financing via OpenBank.
