The Deye SUN-5K-G04 is a single-phase string inverter from the String (G) family, wired L+N+PE and rated at 5 kW of AC output active power. It wakes at a start-up voltage of 80 V, so a partly shaded roof begins exporting well before full sun, and from there it tracks anywhere between 70 V and 500 V across two independent MPPTs fed by one string each. That two-tracker layout suits a villa or a small commercial rooftop whose roof faces point in different directions and never peak together. Up to 6500 W of PV input can be connected, with a 550 V ceiling on PV input voltage and 19.5 A of short-circuit current tolerated per input. On the grid side the SUN-5K-G04 delivers 220/230 V at up to 25 A, for a maximum apparent power of 5500 VA. Its IP65 enclosure is naturally cooled, stays under 35 dB, weighs 8 kg and measures 330 x 323 x 190 mm. Deye states a 5-year warranty on the SUN-5K-G04. We are an authorised Deye distributor and supply the SUN-5K-G04 from our own stock, with technical support before and after the sale.

Yes. The SUN-5K-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-5K-G04 supports up to 6.5kW of PV input, allowing for high DC/AC ratios.
Yes. With 5 kW of rated output, zero export and VSG support, the SUN-5K-G04 suits small commercial sites as well as homes.
