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.

113 of 134 Deye inverter records state output derates from 45 °C, and 30 units are rated to 65 °C ambient. What that means on an August rooftop, and how shade and clearance change it.
Read: Do Solar Inverters Lose Power in Abu Dhabi's Summer Heat? →Every Deye inverter that publishes a derating point publishes 45 °C, so in Riyadh the row that decides your shortlist is the ambient ceiling — 60 °C on every hybrid, 65 °C on 30 models. Here is how to read it.
Read: Best Solar Inverter for a Riyadh Villa: What Happens Above 45 °C →Every Deye inverter is dust-tight — 122 records IP65, 12 IP67. So the dust cost is on the panel glass, not in the box. What an IP rating promises, and how MPPTs and string monitoring contain a dirty roof.
Read: Does Dust Ruin Solar Panels in Sharjah and Ajman? →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-3.6K supports up to 4.7kW PV input, while the SUN-6.2K supports up to 8.06kW, allowing for high DC/AC ratios.
Yes! With power ratings from 3.6kW to 6.2kW and advanced features like zero export and VSG support, it's suitable for both residential and commercial installations.
