The Deye SUN-33K-G04 is a 33 kW three-phase on-grid string inverter from the G04 series, connected 3L+N+PE to a 220/380 V or 230/400 V network. Its rated AC output is 33000 W, and it sustains 36.3 kVA of apparent power at 50 A per phase. Two MPP trackers take three strings each and up to 42.9 kW of PV input, so a mid-scale commercial rooftop can be deliberately oversized against dust, haze and low winter sun. Strings may reach 1100 V, are tracked between 200 V and 1000 V, and wake the inverter at 250 V. Intelligent air cooling holds the IP65 cabinet under 60 dB, full power runs to 45 °C inside a -25 to 60 °C envelope, and the rating stands at 4000 m. At 28.7 kg in a 330 x 572 x 206 mm case, the SUN-33K-G04 is a two-person lift. RS485 and RS232 feed Wi-Fi, Bluetooth, 4G, GPRS or optional LAN monitoring, under a stated 5-year warranty. We are an authorised Deye distributor and supply the SUN-33K-G04 from our own stock, with technical support before and after the sale.
