Solis Three Phase US Inverters 125-255kWus

Reliability Safety Capacity

Solis-(125-255)K-EHV-5G-US

600V: 125K-PLUS / 185K / 185K-PLUS; 800V: 255K / 255K-PLUS

125-255kW three-phase utility-scale 1500 Vdc PV string inverters have 9 MPPT (125K) or 12 independent MPPTs (185 & 255K) with high-rated dc inputs that support "Y" type connection in DC side, up to 30A per DC input . Maximum string input current 15A, support bifacial modules access. Supports anti-PID function to improve system efficiency. High-precision intelligent PV string monitoring reduces fault location time.
