Solis Three Phase Grid-Tied Inverter

S5-GC(75-125)K-US string inverters are suitable for three-phase commercial rooftop or ground mount projects and work efficiently with 600V or 1000VDC arrays. Solis string inverters have high input currents, which enable support of larger PV modules without compatibility issues, better supporting power density and flexibility. Wider operating voltages support operation for longer periods throughout the day, resulting in better system yields. Commissioning, operations and management are simplified through state-of-the-art design and monitoring. Optimized DC and AC connect ports reduce the cost of system cables. Tested to the harshest conditions, Solis’ success in the market and global top ratings are largely in part due to the quality we strive for. This product line is also certified PVRSS and UL3741 compliant, meaning that you can realize cost and time savings by supporting simpler installs.
