What the GoodWe 25kW ET Hybrid Inverter Is Designed For
The GoodWe GW25K-ET is designed to manage power from large solar PV arrays, high-voltage battery systems, and the three-phase utility grid. It supports both grid-connected and backup operation, supplying critical loads with UPS-level switching during grid outages.
This inverter is intended for high-power installations where peak shaving, energy cost optimisation, and reliable backup power are required. It is not a small residential inverter and should be deployed as part of a professionally designed three-phase solar system.
High-Voltage Battery Compatibility of the GoodWe GW25K-ET
The GoodWe 25kW ET Series hybrid inverter supports high-voltage lithium-ion battery systems with a nominal battery voltage of 500V and an operating voltage range of 200–800V. Dual battery inputs allow higher charging and discharging power, enabling strong backup performance and large-scale energy storage.
Battery charging and discharging behaviour is controlled through compatible battery management systems to ensure safe and efficient operation.
Solar Input and MPPT Architecture of the GoodWe 25kW ET Series
The GoodWe GW25K-ET supports up to 37.5kW of solar PV input and features three independent MPPT trackers. This allows flexible PV array layouts across multiple roof orientations and supports large commercial rooftop installations.
A wide MPPT voltage range and high MPPT efficiency ensure maximum solar energy harvesting throughout the day.
Backup Power, Peak Shaving and Parallel Operation
The GoodWe 25kW ET hybrid inverter provides powerful backup capability with UPS-level switching for critical loads. It supports peak shaving functionality, allowing large sites to reduce grid demand charges by limiting peak power draw.
Multiple GoodWe ET Series inverters can be connected in parallel to scale system capacity for larger commercial or industrial installations.
