Solis S6 25 kW 3 Phase Hybrid Inverter for HV Batteries, LV Grid – Without Display

The Solis S6 25 kW 3 Phase Hybrid Inverter for HV Batteries, LV Grid – Without Display is a transformer-less, IP66 power hub that pairs up to 50 kW of PV with high-voltage (150–800 V) battery storage while delivering seamless backup on a 3 × 230 V supply. Three independent MPPT trackers accept 150–850 V strings and 40 A per input, so designers can run six high-current module strings and oversize the array to 200 % of inverter rating for maximum winter harvest.
