Trina TRH

What the Trina TRH 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 Trina TRH range spans 6 kW to 12 kW of AC output, suiting arrays of about 6–7.8 kWp at the small end and 12–15.6 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 5,400 to 10,800 kWh a year, assuming a conservative 900 kWh per kWp. For the smallest model, that is worth €416 a year fed into the grid at 7.70 ct per kWh, and up to €1,998 used at home instead of buying power at 37.0 ct.
