Description Datasheet

Solis > 75,000 Watt 480 VAC Three Phase Commercial Inverter

The Solis Solar S5-GC75K-US is the preferred PV string inverter for large commercial rooftop or ground mount PV projects. The S5-GC75K-US inverter features 10 independent MPPTs with very wide full-power operating ranges that can work efficiently with both 600Vdc and 1000 Vdc PV arrays. String current up to 16A, perfectly accommodates new high-power and bi-facial PV modules. Easy-to-use online O&M tools make O&M more intelligent and convenient. Optimized DC&AC interconnection will reduce the cost of system cables. Enclosures rated to IP66 protection grade can be installed in the harshest environmental conditions.
