The Deye SUN-70K-G03 is a three-phase string inverter of the G03 series, wired 3L+N+PE, whose rated AC output active power is 70 kW, a size that suits an irrigation pumping station, a packing plant or a mid-sized industrial roof. Four MPPT trackers, each holding four strings at up to 40 A, receive as much as 91 kW of maximum PV input power, a DC figure deliberately above the AC rating so the array keeps the machine near full output through hazy hours. The 200-850 V tracking range, the 250 V startup and a 1000 V input limit define how long the strings may be. AC output is 220/380 V or 230/400 V at 50 or 60 Hz, 77 kVA apparent, 106.1 A rated per phase, with THDi under 3%, power factor adjustable from 0.8 leading to 0.8 lagging and 98.7% peak efficiency. It weighs 81 kg, seals to IP65, works to 4000 m, and the stated warranty runs 5 years. We are an authorised Deye distributor and supply the SUN-70K-G03 from our own stock, with technical support before and after the sale.
