About the Deye String Inverter 4.2 kW Single-Phase SUN-4.2K-G04 in Yemen

Fan-free and quiet under 35 dB, the Deye SUN-4.2K-G04 is a 4.2 kW single-phase string inverter for a house or small workshop on an L+N+PE supply. Natural convection cooling in an IP65 case means nothing spins, so the unit can hang in a utility room or a stairwell without being heard, and at 8 kg with a 330 x 323 x 190 mm footprint one installer can mount it alone. Rated AC output is 4200 W, or 19.1 A at 220 V, with 4.62 kVA available as apparent power. Two MPP trackers carry one string each, up to 5.46 kW of modules and 550 V, and their 70-500 V window with an 80 V startup voltage brings a short east-facing string online early in the day. Efficiency peaks at 97.5%. RS485, RS232 and Wi-Fi, Bluetooth, 4G or GPRS monitoring are supported, with a stated 5-year warranty. We are an authorised Deye distributor and supply the SUN-4.2K-G04 from our own stock, with technical support before and after the sale.
