Deye 75 kW Three-Phase String Solar Inverter SUN-75K-G03

The Deye SUN-75K-G03 is a 75 kW three-phase string inverter, connected 3L+N+PE, from the G03 commercial line, aimed at supermarket, cold-store and logistics-depot roofs. Its four MPPT trackers accept four strings apiece and tolerate 60 A of short-circuit current per input, taking a maximum PV input power of 97.5 kW, which is the DC ceiling and distinct from the 75 kW rated AC output active power. The trackers hold 200-850 V, wake at 250 V and accept 1000 V open circuit, with 600 V as the rated PV input. On the grid the unit produces 82.5 kVA of apparent power and 113.6 A of rated output current at 220/380 V or 230/400 V, 50 or 60 Hz, and supports zero export where the utility caps feed-in. Efficiency peaks at 98.7%, with 98.1% on the European weighting. Intelligent air cooling, IP65 sealing, a DC switch and Type II surge protection on both sides suit an install to 4000 m; the warranty is a stated 5 years. We are an authorised Deye distributor and supply the SUN-75K-G03 from our own stock, with technical support before and after the sale.
