About This Product

The GoodWe 5kW 3 Phase SDT G3 Solar Inverter Dual MPPT IP66 AC With WIFI is a three-phase grid-connected solar inverter designed for residential and small commercial PV systems. The GW5000-SDT-30 provides 5kW nominal AC output with two independent MPPT trackers, allowing two separate solar array orientations or roof sections to be managed independently. It supports modern high-current solar modules, includes integrated DC switching and key electrical protection functions, and uses natural convection cooling without a cooling fan.

Who This Product Suits

This inverter suits three-phase homes and smaller commercial properties requiring a 5kW grid-connected solar inverter. Its two MPPT inputs are useful where panels are installed across two roof orientations or where separate strings operate under different solar conditions. The IP66 enclosure also makes it suitable for correctly installed indoor or outdoor locations.

Specifications Explained

The GW5000-SDT-30 has a nominal AC output of 5kW and can provide up to 5.5kW maximum AC active power. It uses two MPPT trackers with one string per MPPT, a maximum DC input voltage of 1100V, an MPPT operating range of 140V to 1000V and a 160V start-up voltage. Maximum input current is 22A per MPPT, with a maximum short-circuit current of 27.5A per MPPT. Maximum efficiency is 98.4%. Integrated protections include PV reverse-polarity protection, insulation resistance detection, residual-current monitoring, anti-islanding protection, AC overcurrent and short-circuit protection, AC overvoltage protection and remote shutdown. Communications include RS485 and WiFi/LAN/Bluetooth connectivity, with monitoring available through GoodWe’s app platform.

Summary

The GoodWe 5kW SDT G3 is a practical three-phase string inverter for 5kW solar installations requiring dual MPPT operation and high-voltage PV input capability. Its 22A-per-MPPT input rating supports contemporary higher-current modules, while IP66 protection, natural convection cooling and integrated monitoring and protection functions make it well suited to straightforward residential and light commercial installations.
