The solution we suggest for single-phase systems is Elios4you for systems up to 6kWp. With the free “Elios4you” App for Android/iOS devices, it is possible to visualize data of production / consumption and the energy exchanged with the grid. This will allow you to maximize self-consumption from your solar PV system, and to cut down your electricity bill.
Elios4you allows you to activate an electrical load depending on the surplus energy available. It is typically employed with a heat pump.
