What the SUNGROW SG12KTL-M 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 12 kW of AC output, the SUNGROW SG12KTL-M suits an array of about 12–15.6 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 10,800 kWh a year, assuming a conservative 900 kWh per kWp: worth €832 a year fed into the grid at 7.70 ct per kWh, and up to €3,996 used at home instead of buying power at 37.0 ct.
Estimates. Electricity prices: BDEW Strompreisanalyse, autumn 2026; Bundesnetzagentur, EEG feed-in tariffs from 1 August 2026.
