Description
Sungrow SH50/80CX 50 and 80 kW Three-Phase Hybrid Inverter
The Sungrow SH50CX and SH80CX are 50 and 80 kW three-phase hybrid inverters for commercial and industrial PV installations with DC-coupled energy storage.
They offer 5 MPPTs on the SH50CX and 10 MPPTs on the SH80CX, AFCI 3.0+ protection, PID Zero and IP66 enclosure protection. The datasheet specifies backup switching within 10 ms under the applicable Sungrow system design and installation conditions.
