Rated at 22 kW of AC output, the Deye SUN-22K-G05 is a three-phase string inverter in the String (G) line for commercial arrays that already fill a 20 kW slot and need more headroom. It connects as 3L+N+PE at 220/380 or 230/400 V, giving 33.4 A per phase at rated power and up to 36.7 A at its 24.2 kVA apparent-power ceiling. Grid quality is held to under 3% current distortion with DC injection below 0.5% of rated current, and the power factor is adjustable from 0.8 leading to 0.8 lagging, which lets a plant meet a utility reactive-power schedule without extra equipment. Zero-export control is supported, so a 22 kW plant on a no-feed-in connection can still consume everything it makes on site. Two MPPTs cover up to 28.6 kW of modules, each tracker handling two strings and 26 A. The IP65 enclosure runs from -25 to 60 °C and is backed by a stated 5-year warranty. We are an authorised Deye distributor and supply the SUN-22K-G05 from our own stock, with technical support before and after the sale.

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.

The SUN-22K-G05 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-22K-G05 series operates with an MPPT voltage range of 200-1000V, providing flexibility in solar panel selection and system design.
Yes! Zero export functionality allows you to manage energy consumption and comply with grid export limits, maximizing self-consumption.
