Lithium  small, intelligent system for storage of electrical energy in order to increase the electricity self-consumption and autarky rate.

A DC-coupled PV system is used to charge the lithium iron phosphate battery. A connected 3-phase sensor registers energy flows at the meter. According to that the battery will charge from or discharge to the connection phase to balance the self-consumption. The emergency power function supplies loads even in the case of power grid failure.

The compact size of the storage system facilitates transport and installation. For monitoring there is a webpage and an app for smartphones.
