What Are Socket Storage Devices And How Do They Help With Self-Consumption?

Socket storage units are compact, mobile battery systems for balcony and mini PV systems that store solar power directly and feed it into the grid via standard Schuko sockets. With capacities from 800 Wh to 2.5 kWh, they increase self-consumption to up to 80%, save up to €400 annually, and can be installed in minutes – without an electrician. DRBO Greenenergy offers suitable plug-and-play solutions for balconies and terraces.

What Exactly are Socket Storage Units?

Socket storage units are LiFePO4 batteries with an integrated inverter that can be connected directly to household sockets. During the day, they charge up to 800 W of solar power and feed up to 350 W back into the house grid. App control, IP65 protection, and expandability make them flexible. DRBO Greenenergy supplies SunLit-compatible models for renters and homeowners that are removable and easy to use.

How Do Socket Storage Units Work?

Solar power is charged via the PV modules during the day. An integrated AC inverter feeds the power into the house grid as needed. Intelligent energy management systems prioritize self-consumption and prevent backflow to the grid. DRBO Greenenergy SunLit storage units support bidirectional charging with 95% efficiency and over 6,000 charging cycles. Smart meters for zero export are integrated.

What Advantages Do Socket Storage Units Offer?

Socket storage units increase self-consumption to 80%, enable weather-independent use, emergency power, and flexible placement. They are 70% cheaper per kWh than fixed storage units, portable, and easy to install. DRBO Greenenergy emphasizes mobility, app control, and quick amortization (2–3 years).

What Socket Storage Models Are Available?

Popular models: Anker Solix XS1 (1 kWh), Marstek B2500 (2.2 kWh), Hoymiles ES3.0 (3 kWh). All feature app control, WiFi, and 350 W output. DRBO Greenenergy recommends SunLit variants with Deye technology. Selection by household size: 1 kWh for 1–2 people, 2 kWh for families.
