The Deye SUN-90K-G03 is a three-phase string inverter from the G03 series carrying 90 kW of rated AC output active power, sized for a hotel or hospital campus array whose load runs right through the day. Six MPPT channels, four strings on each, gather up to 135 kW of maximum PV input power, the DC-side figure, at 40 A per input and a 1000 V limit, tracking from 200 V to 850 V and starting at 250 V. That much DC oversizing lets the block hold its 99 kVA of apparent power for longer either side of noon. Output is 220/380 V or 230/400 V at 50 or 60 Hz, 150 A maximum per phase, 98.8% peak and 98.2% European efficiency, with RS485, RS232, Wi-Fi and LAN available for monitoring. Intelligent air cooling, an IP65 enclosure of 81 kg and 824 x 516 x 312.7 mm, and operation to 4000 m and 60 degrees Celsius complete it, under a stated 5-year warranty. We are an authorised Deye distributor and supply the SUN-90K-G03 from our own stock, with technical support before and after the sale.
