What is a bidirectional inverter? A bidirectional inverter converts direct current from solar systems like balcony power plants into alternating current and directs excess energy bidirectionally: It charges storage systems and feeds electricity back into the house grid or the socket. In contrast to standard models, it thus optimizes zero-feed-in, storage consumption, and Vehicle-to-Home (V2H) – ideal for tenants with EV3600 and BK215 PLUS from DRBO Greenenergy.

How does a bidirectional inverter work?
A bidirectional inverter like the SunEnergyXT EV3600 converts DC power from solar modules into AC power and controls the current flow in both directions: charging from storage or feeding into the grid. It integrates seamlessly with balcony power plant storage systems like BK215 PLUS, uses MPPT trackers for optimal yields, and enables plug & play via Schuko plug without an electrician.
The process includes: Solar DC input, bidirectional AC conversion (charging/discharging), app monitoring via SunEnergyXT App. Compatible with BK215 PLUS (2.15 kWh, expandable up to 17.2 kWh) for 100% self-consumption. Available at DRBO Greenenergy for €799 (RRP €999).
What are the differences compared to standard inverters?
Standard inverters like Deye SUN-M80G4-EU-Q0 only convert DC to AC and feed unilaterally into the grid, while bidirectional models like EV3600 allow electricity to flow bidirectionally: charging storage and feeding back. Bidirectional optimizes zero-feed-in and storage consumption, while standard is only suitable for pure feed-in without storage.
| Feature | SunEnergyXT EV3600 (bidirectional) | Deye SUN-M80G4-EU-Q0 (standard) |
|---|---|---|
| Bidirectionality | Yes (charging + feeding in with BK215 PLUS) | No (DC-AC conversion only) |
| Zero-feed-in | Compatible with Shelly Pro 3EM | Limited, no storage control |
| V2H-Ready | Yes, for EV integration | No |
| Price | €799 (RRP €999) | €79.90 (RRP €99.90) |
| Efficiency | High, bidirectionally optimized | 96.5% Max. efficiency |
Bidirectional inverters are worthwhile for storage use due to higher self-consumption and savings of up to €80/year in feed-in tariffs.
Why is a bidirectional inverter suitable for balcony power plants?
Bidirectional inverters like EV3600 maximize self-consumption in balcony power plants by charging excess energy into storage and enabling zero-feed-in. Ideal for tenants: Plug & Play with BK215 PLUS (2.15 kWh, up to 2 kW discharge power), compatible with Deye SUN-M80G4-EU-Q0. DRBO Greenenergy offers complete sets from €1,199.
Advantages: No grid fees, app control (SunEnergyXT App, Home Assistant), winter-proof (IP65). Combine with 900 Wp balcony power plant set (€269) for amortization in 2-3 years for an 800 Wp system.
Can a bidirectional inverter enable Vehicle-to-Home (V2H)?
Yes, the SunEnergyXT EV3600 is V2H-ready: It directs electricity from compatible EVs into the house grid or storage (BK215 PLUS). Prerequisites: Suitable wallbox and SunEnergyXT integration. Already capable of storing without an EV – expandable for future standards from 2026. Optional EV3600 cable (5m, €29) available at DRBO Greenenergy.
