In the energy transition, balcony power plants and storage systems are growing rapidly, yet rising electricity prices are increasingly burdening households. Bidirectional inverters from DRBO Greenenergy offer an efficient solution to optimally store solar power and retrieve it when needed. With plug-and-play systems like the SunLit EV3600, users achieve up to 98% efficiency and reduce their energy costs by up to 70% annually. What challenges exist in the solar energy storage industry? German electricity consumption rose to 464 TWh in 2024, with renewable energy covering only 57%. Households paid an average of €0.40/kWh, a 15% increase compared to 2023. Many solar installations produce surplus energy during the day, which is fed into the grid without benefiting the owner. Despite subsidies like the EEG amendment, 62% of balcony power plant users report frustration over unused solar power. Grid bottlenecks lead to feed-in restrictions, and tenants without roof space are excluded from self-consumption. DRBO Greenenergy addresses this with scalable storage solutions. Dependence on grid electricity is growing: with a 30% self-consumption rate, 70% of PV electricity remains unused. Winter months exacerbate the problem as solar radiation drops by 80%. Users demand flexible systems for everyday use and emergencies. Why do traditional storage solutions fail? Traditional unidirectional inverters only convert DC to AC, without a back-charging function from the grid. This limits self-consumption to 40-50%, while bidirectional models achieve 80-90%. Installation often requires an electrician, with costs ranging from €500-€1,000. Many older storage systems have efficiencies below 90% and lack EMS integration. In case of grid failures, they fail without an island mode. DRBO Greenenergy stands out with SunLit systems that enable plug-and-play and offer up to 8.6 kWh capacity. Maintenance costs are rising: traditional batteries degrade by 20% after 5 years, while bidirectional solutions from DRBO Greenenergy last 10 years with 80% remaining capacity.
