It is a little known fact that solar panels and batteries don't work during a power cut. This is because it uses the Grid to complete the circuit.
When a power cut is detected your sonnenProtect switches over to island mode. Island mode keeps your sonnenBatterie and solar panels running without a problem. In island mode, you will be disconnected from the grid until it is up and running again. The sonnenProtect manages everything for you automatically and seamlessly, you don't have to do a thing.
The sonnenProtect 2500 is for a sonnenBatterie hybrid system. The sonnenProtect 1300 works with Sonnen AC batteries.
Founded in 2010 to support distributed generation and increased customer autonomy by providing energy storage solutions. Sonnen were the first company to build a fully-integrated li-ion residential energy storage system.
