About This Product

GoodWe GW5000-SDT-AU30 is a 5 kW three-phase grid-connect solar inverter from GoodWe’s SDT G3 Series. It is designed for three-phase residential solar systems and smaller commercial installations where a straightforward, non-hybrid inverter is required. This model supports three MPPT inputs, making it useful where panel strings may be split across different roof faces or orientations. It is a solar inverter only, not a battery inverter or backup power unit.

Who This Product Suits

GoodWe GW5000-SDT-AU30 suits homes or small sites with three-phase supply that need a 5 kW AC solar inverter. GoodWe has built this model for standard grid-connected PV systems rather than off-grid or battery-backup applications. It is a practical option for installers working with modern high-current solar panels, multiple roof orientations, and sites where export limiting or monitoring may be required. Final suitability still depends on the string design, local network rules, and the electrical layout of the property.

Specifications Explained

GoodWe GW5000-SDT-AU30 has a nominal AC output of 5,000 W and is made for 230/400 V three-phase grid connections. The inverter allows up to 7,500 W of PV input, giving up to 150% DC oversizing where the system design and local rules allow it. It uses three MPPT trackers with one string per MPPT on this 5 kW model, with up to 16 A input current per MPPT and a maximum DC input voltage of 1,100 V. The MPPT operating voltage range is 140-950 V, with 160 V start-up voltage and 600 V nominal input voltage.

Protection and operating features include integrated PV string current monitoring, insulation resistance detection, residual current monitoring, reverse polarity protection, anti-islanding protection, AC overcurrent protection, AC short-circuit protection, AC overvoltage protection, an integrated DC switch, Type II DC surge protection and Type II AC surge protection. The model is IP66 rated and uses smart fan cooling. User interface and communications include LED indication, WLAN and app access, with RS485 and optional Wi-Fi, LAN, 4G or Bluetooth depending on configuration. Optional features include AFCI, remote shutdown, PID recovery and LCD display.

Summary

GoodWe GW5000-SDT-AU30 is a 5 kW three-phase GoodWe SDT G3 inverter for grid-connected solar systems. Its main strengths are three MPPTs, high-current PV string compatibility, 150% DC oversizing capability, IP66 protection and a solid set of built-in electrical protections. It is best suited to three-phase residential or small commercial PV jobs where a reliable solar-only inverter is required. It should not be presented as a hybrid, battery-ready or backup inverter.
