The Deye SUN-4.2K-G05P1-EU-AM2 is a 4.2 kW single-phase string inverter in the String (G) line, a half-step above the 4 kW frame for homes whose consumption has outgrown it. Its two MPPT inputs are rated at 18 A of operating current each and withstand 27 A of short-circuit current per input, which means most modern high-current modules can be strung without derating the tracker. Up to 6.3 kW of PV can be connected under a 550 V ceiling, tracked between 70 and 500 V from an 80 V startup. Rated AC output is 4.2 kW at 220 or 230 V on an L+N+PE connection, with 4.62 kVA of apparent power and a maximum output current of 21 A. Reverse-polarity protection, insulation impedance detection and a built-in DC switch cover the array side. Weighing 7.7 kg in an IP65 case, the inverter carries a stated 5-year warranty. We are an authorised Deye distributor and supply the SUN-4.2K-G05P1-EU-AM2 from our own stock, with technical support before and after the sale.

View error codes for this device →Yes. The SUN-4.2K-G05P1-EU-AM2 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-4.2K-G05P1-EU-AM2 has 2 MPPT trackers with 1+1 strings, each tracked independently across a 70-500 V MPPT range, so strings with different orientations or partial shading do not pull each other down.
On the SUN-4.2K-G05P1-EU-AM2, 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.
