Solis 350KW Three Phase HV String Inverter (12 MMPT)
Solis S6 GU350K EHV three-phase PV inverters with a power of 350kW, 1500V DC input and 800 VAC output are designed to provide a more cost-effective adaptive solution for utility PV projects. It has maximum efficiency of up to 99%, with 12/16 MPPTs and 32 inputs, the string current is 20A, with perfectly matching efficient high-power PV module. Optimized DC, AC interface, and the PLC communication mode is matched to effectively reduce the investment cost of PV projects. it offers protection level up to IP66 , making the PV plant safer and more stable. High-precision strings monitoring and I-V curve scanning effectively improve plant O&M efficiency and reduce subsequent O&M costs.
