SUN-125K-SG02-HP3-EU

The Deye SUN-125K-SG02HP3-EU-GM10 is a 125kW three-phase high-voltage hybrid solar inverter designed for commercial and industrial solar PV systems with battery energy storage. It supports lithium-ion batteries within a 160–1000V voltage range and provides two battery inputs with a maximum charging/discharging current of 100+100A.

Equipped with 10 MPPT trackers, the inverter supports maximum PV access power of 250,000W and maximum PV input power of 200,000W. Its rated AC input/output active power is 125,000W, with maximum apparent power of 135,000VA and maximum conversion efficiency of 98.7%.

The inverter supports AC coupling for existing solar installations, diesel generator energy storage integration, six programmable battery charging/discharging periods and parallel operation of up to 10 compatible units. With IP65 protection, intelligent air cooling and multiple communication options, it is designed for scalable commercial and industrial solar energy storage applications.
