Sunarix SX-HIN-12kW-3PH

What the Sunarix SX-HIN-12kW-3PH does

A hybrid inverter runs both the solar array and a home battery: it supplies the home from the panels first, stores the surplus and draws on the battery when the sun goes down. With 12 kW of AC output, the Sunarix SX-HIN-12kW-3PH suits an array of about 12–15.6 kWp, as installers commonly size the panels up to 30% above the inverter's rating.

In Germany, an array of the same size produces about 10,800 kWh a year, assuming a conservative 900 kWh per kWp: worth €832 a year fed into the grid at 7.70 ct per kWh, and up to €3,996 used at home instead of buying power at 37.0 ct.
