About This Product

The GoodWe 29.9kW 3 Phase SDT G3 Solar Inverter Three MPPT IP66 AC With WIFI is a grid-connected three-phase solar inverter designed for larger residential and small commercial PV systems. It provides 29.9kW nominal AC output and uses three independent MPPT trackers to manage multiple solar array sections. The inverter supports high-voltage PV strings, integrated system protection and remote monitoring through GoodWe communication options.

Who This Product Suits

This inverter suits three-phase properties requiring a relatively large rooftop solar system, including large homes, workshops, farms, offices, retail buildings and smaller commercial sites. The three MPPT inputs are particularly useful where panels need to be divided across different roof faces, orientations or electrically separate strings.

Specifications Explained

The inverter has a nominal AC output of 29.9kW and supports up to 45kW of connected PV input. Its three MPPT trackers operate across a 140-950V range, with a maximum DC input voltage of 1100V and 160V start-up voltage. Each MPPT supports two strings on this model, with up to 40A input current per MPPT. Maximum inverter efficiency is 98.7%. Integrated protection includes DC and AC Type II surge protection, anti-islanding protection, residual-current monitoring, PV reverse-polarity protection, AC overcurrent protection and a DC isolating switch. The enclosure is rated IP66, and monitoring communication can be provided through WiFi, LAN and Bluetooth configurations.

Summary

The GoodWe 29.9kW SDT G3 is a practical three-phase inverter for larger grid-connected solar installations. Its 29.9kW output, three MPPT trackers, high PV input capacity, 98.7% maximum efficiency and IP66 enclosure make it suitable for Australian residential and commercial installations where multiple strings and flexible array design are required.
