Solis S6 8.0 kW 3 Phase Hybrid Inverter for HV Batteries, LV Grid – Without Display

Designed for small commercial and premium residential sites, the Solis S6 8.0 kW 3 Phase Hybrid Inverter for HV Batteries, LV Grid – Without Display unites 16 kW of PV, an 8 kW high-voltage battery channel and seamless UPS-grade backup in one IP66 aluminium chassis. Four independent MPPTs (200–850 V, 4 × 16 A) let you oversize the array to 160 % so winter harvest isn’t left on the roof, while transformer-less conversion delivers up to 96.7 % peak efficiency and < 25 W night self-use to protect stored energy.
