About the Deye 50 kW Three-Phase String Solar Inverter SUN-50K-G04

The Deye SUN-50K-G04 is a 50 kW three-phase on-grid string inverter with four MPP trackers, the widest array management in the G04 range. Twelve strings, three per tracker, carry up to 65 kW of PV into a 50000 W rated AC output, which gives a commercial or light-industrial roof room to face modules in four directions and still keep each orientation on its own tracker. Input voltage is capped at 1100 V with tracking from 200 V to 1000 V and a 250 V startup. On the grid side the inverter supplies 75.8 A per phase at 220/380 V, 83.3 A maximum and 55 kVA apparent, at 98.7% peak efficiency. The 39 kg IP65 cabinet of 434 x 570 x 243 mm uses intelligent air cooling under 65 dB and is approved to 4000 m. RS485, RS232, Wi-Fi and LAN are provided, with a stated 5-year warranty. We are an authorised Deye distributor and supply the SUN-50K-G04 from our own stock, with technical support before and after the sale.
