Blackout protection with sonnenProtect

Protect your home against power blackouts and power outages with sonnenProtect. sonnenProtect is a small, optional add-on device for your sonnenBatterie home battery system that can provide backup power to critical appliances when the electricity grid goes down.

The sonnenProtect unit can be wired to specific emergency power outlets around your home to enable continued operation of your most critical appliances – such as a refrigerator, fans, water pumps, computers, charging devices or lighting.

Your sonnenProtect device can power up to 1.3kW of appliances and will draw power from the free solar energy stored in your sonnenBatterie.
