Fan-free and quiet under 35 dB, the Deye SUN-4.2K-G04 is a 4.2 kW single-phase string inverter for a house or small workshop on an L+N+PE supply. Natural convection cooling in an IP65 case means nothing spins, so the unit can hang in a utility room or a stairwell without being heard, and at 8 kg with a 330 x 323 x 190 mm footprint one installer can mount it alone. Rated AC output is 4200 W, or 19.1 A at 220 V, with 4.62 kVA available as apparent power. Two MPP trackers carry one string each, up to 5.46 kW of modules and 550 V, and their 70-500 V window with an 80 V startup voltage brings a short east-facing string online early in the day. Efficiency peaks at 97.5%. RS485, RS232 and Wi-Fi, Bluetooth, 4G or GPRS monitoring are supported, with a stated 5-year warranty. We are an authorised Deye distributor and supply the SUN-4.2K-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-4.2K-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.
