What the KOSTAL Industrie Elektrik PLENTICORE MP M G3 4.6 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 4.6 kW of AC output, the KOSTAL Industrie Elektrik PLENTICORE MP M G3 4.6 suits an array of about 4.6–6 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 4,140 kWh a year, assuming a conservative 900 kWh per kWp: worth €319 a year fed into the grid at 7.70 ct per kWh, and up to €1,532 used at home instead of buying power at 37.0 ct.
