Hatch Solar HSEU

What the Hatch Solar HSEU 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. The Hatch Solar HSEU range spans 600 W to 2 kW of AC output, suiting arrays of about 0.6–0.8 kWp at the small end and 2–2.6 kWp at the large end, as installers commonly size the panels up to 30% above the inverter's rating.

In Germany, arrays of the same size produce about 540 to 1,800 kWh a year, assuming a conservative 900 kWh per kWp. For the smallest model, that is worth €42 a year fed into the grid at 7.70 ct per kWh, and up to €200 used at home instead of buying power at 37.0 ct.
