What the Vision UPS batterX h10 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 10 kW of AC output, the Vision UPS batterX h10 suits an array of about 10–13 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 9,000 kWh a year, assuming a conservative 900 kWh per kWp: worth €693 a year fed into the grid at 7.70 ct per kWh, and up to €3,330 used at home instead of buying power at 37.0 ct.
