About This Product

The GoodWe 25kW Three Phase ET SERIES Solar Hybrid Inverter IP66 is a high-voltage three-phase hybrid inverter designed for solar + battery systems. It acts as the central energy conversion and management unit, converting DC power from PV panels (and batteries) into 3-phase AC power for household or small commercial use. It supports full hybrid operation ‘ solar generation, battery charge/discharge, and grid interaction ‘ with integrated load management, peak shaving, and backup-power capability, making it suitable for installations needing both energy self-consumption and backup supply reliability.

Who This Product Suits

This inverter is well suited to large residential systems, small commercial premises, or light industrial sites that run on three-phase supply. It’s ideal when you plan to pair solar panels with a high-voltage battery bank (such as a compatible lithium-ion battery) to store excess solar energy and run loads off-grid during blackout or peak-tariff periods. It also works for households wanting to manage and reduce grid consumption using peak shaving, especially when there are significant loads like air conditioners, heaters or large motors.

Specifications Explained

• AC Output: 25 kW (three-phase) ‘ delivers robust power for three-phase loads or whole-house supply.
• Hybrid Inverter with Battery Support ‘ accepts high-voltage batteries (battery voltage range circa 200’800 V) for solar storage and off-grid/back-up operation.
• 3 MPPT Inputs with up to 30 A per MPPT ‘ allows flexible PV array configurations and ensures efficient maximum power tracking under varying conditions.
• High DC Input Capacity ‘ supports substantial PV string input (e.g. up to 37.5 kW DC), enabling oversizing of PV modules for higher output even in lower light conditions.
• IP66 Enclosure ‘ dust-tight and protected against powerful water jets, suitable for outdoor or semi-outdoor installations.
• Backup / Black-Start Capability & Peak Shaving ‘ can supply emergency 3-phase power during outages and manage grid import to flatten demand peaks and reduce energy costs.
• Integrated Load Control & Dry-Contact Output ‘ allows connection of external loads (e.g. heat pump, hot water system) to smartly control power draw or battery discharge, optimising self-consumption.
• Communication Ports (RS485 / CAN / optional Wi-Fi) ‘ enables system monitoring, remote control and compatibility with energy management systems.
• Fan Cooling & Wide Operating Range ‘ designed to operate in typical Australian climates and conditions, including variation in temperature and humidity.

Summary

The GoodWe 25kW Three Phase ET SERIES Solar Hybrid Inverter IP66 is a heavy-duty, three-phase hybrid inverter built for serious solar installations that combine panels with a battery. It’s robust, versatile and designed to deliver reliable AC output, efficient energy conversion and flexible load or backup management. With support for high-voltage batteries, multiple MPPT inputs, load control and an outdoor-rated enclosure, it suits both larger homes and small commercial setups. If you need a dependable inverter that handles solar generation, energy storage and backup supply in a compact, smart package ‘ this model is a solid fit.
