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.

Frequently Asked Questions
How much PV can the SUN-40K-G04 take, and how are the strings arranged?
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.
Does the SUN-40K-G04 support zero export on a commercial site?
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.
What grid connection does the SUN-40K-G04 need?
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.
Will the SUN-40K-G04 hold output through a Gulf summer?
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.
Is the Deye SUN-45K-G04 suitable for the Middle East climate?
Yes. The SUN-45K-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.
What is the maximum PV input power?
The SUN-45K-G04 series supports up to 58.5kW of PV input power, allowing for high DC/AC ratios and maximum energy harvest.
Does it support Anti-PID function?
Yes, as an option. On the SUN-45K-G04, Anti-PID is an optional function: it counters potential-induced degradation (PID) of the connected solar panels, which otherwise erodes their output over the years.
Is the Deye SUN-50K-G04 suitable for the Middle East climate?
Yes. The SUN-50K-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.
