The GoodWe ET series inverters are designed for high-power photovoltaic rooftops, ideal for commercial and industrial (C&I) energy storage solutions. They meet the demands of powerful solar installations, facilitating energy backup, peak shaving, and load management for optimized autonomy and reduced energy costs.
As PV modules become more powerful, system designs must evolve. The GW40K-ET inverter incorporates the latest technology to efficiently meet the requirements of energy storage installations.
This GoodWe inverter offers optimized energy autonomy with the ability to supply 100% unbalanced loads, compensating for different loads in self-consumption or backup modes. The UPS-equivalent switchover time ensures continuous power supply and reduces the risk of interruptions for critical loads when combined with the STS (Static Transfer Switch) device.
