AEconversion INV315-50EU

What the AEconversion INV315-50EU does

A microinverter sits behind one to four panels and converts their output on the roof, so shade or a fault on one panel does not pull down the rest of the array. With 300 W of AC output, the AEconversion INV315-50EU suits an array of about 0.3–0.4 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 270 kWh a year, assuming a conservative 900 kWh per kWp: worth €21 a year fed into the grid at 7.70 ct per kWh, and up to €100 used at home instead of buying power at 37.0 ct.
