Infypower EXP22K3E-FSW-C(Optional：IAU63ATS-AW-1)

What the Infypower EXP22K3E-FSW-C does

A solar string inverter turns the direct current from a rooftop array into grid-quality alternating current for the home, and feeds what the home does not use into the grid. With 22 kW of AC output, the Infypower EXP22K3E-FSW-C suits an array of about 22–28.6 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 19,800 kWh a year, assuming a conservative 900 kWh per kWp: worth €1,525 a year fed into the grid at 7.70 ct per kWh, and up to €7,326 used at home instead of buying power at 37.0 ct.
