About the Deye 40 kW Three-Phase String Solar Inverter SUN-40K-G04 in the UAE

The Deye SUN-40K-G04 is a 40 kW three-phase on-grid string inverter built for commercial rooftops and ground-mount projects. It accepts up to 52 kW of PV across three MPP trackers and nine strings, delivers 40000 W of active power at 98.7% peak efficiency, and connects to a 3L+N+PE grid. Each tracker carries 40 A of operating current over three strings, tracks between 200 V and 1000 V, tolerates 1100 V maximum PV input and starts at 250 V. Output is 60.6 A per phase at 220/380 V or 58 A at 230/400 V, peaking at 66.7 A and 44 kVA apparent power, with THDi below 3% and power factor adjustable from 0.8 leading to 0.8 lagging. European efficiency is 98.1% and MPPT efficiency stays above 99%. The IP65 cabinet measures 434 x 570 x 243 mm, weighs 39 kg and cools by intelligent air flow under 65 dB from -25 to 60 °C, derating from 45 °C and rated to 4000 m. The stated warranty term is 5 years. We supply the SUN-40K-G04 as an authorised Deye distributor.

Frequently Asked Questions

The SUN-40K-G04 accepts up to 52 kW of PV against its 40000 W rated AC output. That array is split across three MPP trackers carrying three strings each, nine in total, with 40 A of operating current and 60 A of short-circuit current per tracker. Design every string inside the 200-1000 V MPPT window, below the 1100 V maximum PV input voltage, and above the 250 V startup point.

Yes. Zero export is supported, alongside anti-islanding protection, residual current detection, DC component monitoring with DC injection below 0.5% of rated current, and insulation impedance detection. Grid regulations covered include IEC 61727, IEC 62116, EN 50549-1, VDE-AR-N 4105, G98, G99, CEI 0-21, NRS 097 and NC RFG, so the same unit suits an export-limited or a fully exporting connection.

It connects as 3L+N+PE at 220/380 V or 230/400 V, on 50 Hz (45-55 Hz) or 60 Hz (55-65 Hz), with an AC voltage tolerance of 0.85 to 1.1 times nominal. Power factor is adjustable from 0.8 leading to 0.8 lagging and current THD stays below 3%. AC overcurrent, overvoltage and short-circuit protection are built in, with Type II surge protection on both the DC and AC sides.

It is rated from -25 to 60 °C and begins derating at 45 °C, so plan a shaded, ventilated position for a rooftop in the Gulf, North Africa or the wider MEA region. The IP65 enclosure tolerates 0-100% ambient humidity, intelligent air cooling keeps noise below 65 dB, and the unit is certified to operate up to 4000 m. Safety conformity covers IEC 62109-1, EN 62109-1, IEC 62109-2 and EN 62109-2.
