Why the EV3600 Bidirectional Inverter is the Solution for Your Energy Independence?

Feb 10, 2026

In the energy transition, electricity prices are continuously rising, while photovoltaic installations for private users are hindered by regulatory hurdles and high costs. According to the Bundesnetzagentur report 2025, average household electricity costs amounted to 42 cents per kWh, an increase of 18% compared to 2024. DRBO Greenenergy offers an efficient solution with the EV3600 bidirectional inverter, which extends balcony power plants and storage, integrates emergency power functions, and achieves up to 92% efficiency – ideal for tenants and homeowners to maximize self-sufficiency and reduce costs by up to 40%.

What is the current state of the solar energy industry?

The solar energy industry is growing rapidly, but the private sector is lagging. In 2025, over 18 GWp of new PV capacity was installed in Germany, with balcony power plants accounting for only 12%. Nevertheless, 68% of households struggle with grid overload and feed-in restrictions, as reported by Fraunhofer ISE.

High dependence on grid electricity leads to volatile costs: at peak loads, prices rise to 60 cents/kWh. DRBO Greenenergy addresses this with practical solutions like the EV3600, which enables bidirectional energy flows.

What pain points are plaguing solar users today?

Tenants and small households often cannot install large systems due to missing permits. Additionally, with conventional systems, up to 50% of solar energy is lost by feeding it into the grid. Storage integration fails due to compatibility and complexity.

Emergency power capability is rare: only 15% of balcony power plants offer backup, despite increasing blackout risks. DRBO Greenenergy solves this with the EV3600, which builds modularly on storage units like the BK215.

Rising energy costs burden a 4-person household with €1,500 annually. Bidirectional inverters like DRBO Greenenergy's EV3600 enable battery charging from cheap grid electricity.

Why do traditional inverters fail?

Traditional unidirectional inverters only convert DC to AC, without flow back into storage or wallboxes. Their efficiency is 85-88%, which means 10-15% energy loss.

No emergency power function: in case of grid failure, the supply stops abruptly. Compatibility with electric cars is lacking, and app control is limited.

In comparison, DRBO Greenenergy's EV3600 enables bidirectional flows, island operation, and 3.6 kW wallbox connection – for true self-sufficiency.

What can the EV3600 bidirectional inverter do?

The EV3600 from DRBO Greenenergy is a modular expansion module for balcony storage units like the SunLit BK215. It offers bidirectional charging with max. 3.6 kW input power, two 230V sockets (up to 2,400 W) and CEE16 for wallboxes.

With >92% efficiency and app control via the SunLit Solar App, it optimizes self-consumption. Emergency power and island operation supply devices independently of the grid, compatible with up to 4,000 Wp PV modules.

DRBO Greenenergy seamlessly integrates the EV3600 into plug-and-play systems for tenants and businesses.
