How does the SunEnergyXT EV3600 transform energy management for solar systems?

The SunEnergyXT EV3600 revolutionizes energy management in solar systems with bidirectional charging and discharging capabilities and emergency power functionality. This expansion module for balcony power plants and storage units like the BK215 maximizes self-sufficiency, reduces costs by up to 30 percent, and enables off-grid operation – ideal for households and businesses. DRBO Greenenergy seamlessly integrates this solution into practical solar packages for tenants and owners.

What is the current situation in solar energy management?

In 2025, solar systems are growing rapidly: according to the Federal Network Agency, over 3 million balcony power plants have been installed in Germany, but 70 percent of users report inefficient self-consumption rates below 40 percent. Prone-to-failure grids and volatile electricity prices burden households with an average of 1,200 euros in additional annual costs. DRBO Greenenergy addresses this with proven storage solutions.

This fragmentation leads to high losses: Fraunhofer ISE reports 25 percent of unused PV energy due to a lack of storage integration. In the event of grid failures, there is no backup, affecting 15 percent of households annually. The energy transition is stalling because 60 percent of systems operate without smart control.

What pain points plague traditional solar systems?

Surplus electricity is fed into the grid instead of being used – a loss of up to 500 kWh per year per system. Without emergency power capability, systems fail during blackouts, as happened in winter 2024/25 with 10 percent outages. DRBO Greenenergy offers robust alternatives with Deye inverters.

High installation costs and complexity deter tenants: 80 percent forego storage due to electrician effort. Dynamic tariffs remain unused, costing 200 euros in annual savings.

Why do traditional solutions fail?

Traditional micro-inverters only feed into the grid without charging storage – self-consumption stagnates at 30 percent. String inverters require expensive retrofitting from 2,000 euros. No AC coupling prevents the use of external PV yields.

Comparison: Standard systems achieve 2 kW of emergency power, but only grid-tied. Storage without bidirectionality does not charge dynamically, costing 15 percent efficiency. DRBO Greenenergy surpasses this with plug-and-play options.
