About the Deye 20 kW Three-Phase String Solar Inverter SUN-20K-G05 in the UAE

The Deye SUN-20K-G05 is a 20 kW three-phase string inverter from the String (G) family, sized for grid-tied rooftops on workshops, cold stores and mid-size commercial buildings. Its rated AC output is 20 kW, delivered on a 3L+N+PE connection at 220/380 or 230/400 V. Two MPPT trackers take 2+2 strings and up to 26 A of operating current each, so a roof split across two orientations behaves as two independent arrays and a shaded string cannot drag its neighbour down. The DC side accepts up to 26 kW of modules below an 1100 V ceiling, tracks from 200 to 1000 V, and starts generating from 250 V, which brings a short string online early in the morning. Peak conversion efficiency is 98.5% against a European weighted figure of 98.0%. The 20 kg IP65 chassis measures 362 x 527 x 220 mm, is certified to 4000 m altitude, includes a DC switch, and carries a stated 5-year warranty. We are an authorised Deye distributor and supply the SUN-20K-G05 from our own stock, with technical support before and after the sale.

Frequently Asked Questions

Is the Deye SUN-20K-G05 suitable for the Middle East climate?

Yes. The SUN-20K-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.

What is the MPPT voltage range?

The SUN-20K-G05 series operates with an MPPT voltage range of 200-1000V, providing flexibility in solar panel selection and system design.

Does it support zero export?

Yes. The SUN-20K-G05 supports zero export: it holds what it feeds to the grid at the export limit you set, so its 20 kW of output serves your own loads first.
