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.

A fault code is the end of a chain, not the start: a protection read a value outside its window and cut the output. Our 134 records name both.
Read: Solar Inverter Fault Codes: The Protections Behind the Number →72 of the 134 Deye inverter records are three-phase, and the noise row runs from under 25 dB to under 65 dB. On an industrial site that second figure decides the mounting position — and it does not track power the way you would expect.
Read: Three-Phase Solar Inverter for a Dammam Factory: Which One, and Where Can You Mount It? →72 of 134 Deye inverter records are three-phase, and every unit rated under 65 dB is one of them. How noise and weight decide between a plant room and an outdoor wall on an RAK site.
Read: Best Three-Phase Solar Inverter for a Business in Ras Al Khaimah →Yes. The SUN-50K-G04 is rated -25 to 60 °C, with derating above 45 °C, which covers the heat and dust of the Gulf, North Africa and the wider MEA region. Mount it in shade for the best summer output. Its IP 65 rating handles dust and humidity.
The SUN-50K-G04 series supports up to 65kW of PV input power, allowing for high DC/AC ratios and maximum energy harvest.
Yes! The optional Anti-PID function helps prevent long-term performance degradation of solar panels, ensuring high efficiency over the system's lifespan.
