About the Deye 23 kW Three-Phase String Solar Inverter SUN-23K-G05

The Deye SUN-23K-G05 is a 23 kW three-phase string inverter, the intermediate step in the String (G) ladder that lets an installer match a 29.9 kW array without moving up a frame size. Monitoring runs over RS485 or RS232, and the communication port takes an optional GPRS, Wi-Fi, Bluetooth, 4G or LAN module, so the same unit reports from a rooftop with no cabling or from a plant room on a wired network. Per-string monitoring and arc-fault detection are offered as options, while DC component monitoring, insulation impedance detection and residual current detection are built in. The rated AC output is 23 kW on a 3L+N+PE connection, rising to 25.3 kVA of apparent power and 38.4 A per phase. Both MPPT trackers work between 200 and 1000 V under an 1100 V input limit. An integrated DC switch and a stated 5-year warranty complete the package. We are an authorised Deye distributor and supply the SUN-23K-G05 from our own stock, with technical support before and after the sale.

Frequently Asked Questions

Is the Deye SUN-23K-G05 suitable for the Middle East climate?

Yes. The SUN-23K-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-23K-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-23K-G05 supports zero export: it holds what it feeds to the grid at the export limit you set, so its 23 kW of output serves your own loads first.
