Q: Is the Deye SUN-M50G4-EU-Q0-I suitable for the Middle East climate?

Yes. The SUN-M50G4-EU-Q0-I is rated -40 to 65 °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 IP67 rating handles dust and humidity.

300W microinverter with single MPPT, IP67 protection, and <100ms AC discharge.

Models Covered: SUN-M30G4-EU-Q0-I, SUN-M40G4-EU-Q0-I, SUN-M50G4-EU-Q0-I

Manufacturer: Ningbo Deye Inverter Technology Co., Ltd

Application: The Deye SUN-M30G4-EU-Q0-I is a single-module micro-inverter from the Micro (M) family, single-phase, rated at 300 W of AC output active power. It is the entry point for balcony solar and small self-consumption additions, where one panel of 210 W to 420 W is bolted to a railing and its inverter goes behind it. The lone MPPT accepts 15 A of operating current and 22.5 A of short-circuit current, and 420 W is the maximum PV input power. Up to 17 of these units may be cabled onto one AC branch, which makes long, thin roof rows practical to wire. After a grid disconnection the AC side discharges in under 100 ms. At 1.85 kg and 173 x 158.5 x 31.5 mm, the sealed IP67 body is small enough to sit inside the module frame, runs silently below 25 dB, and is backed by a stated 10-year warranty. We are an authorised Deye distributor and supply the SUN-M30G4-EU-Q0-I from our own stock, with technical support before and after the sale.

Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in the UAE that rests with the local authorities (DEWA, ADDC, SEWA). Confirm the grid code, import requirements and any local certification with them, or with us, before you order.
