China-headquartered GoodWe has introduced the ET Series 75–100 kW hybrid inverters for C&I storage applications. The system is designed with 8 MPPTs, 200% DC oversizing and AC/DC coupling to increase harvest and allow flexible configurations. The inverters have dual 110 A battery inputs that support 220 A charge-discharge capability for peak-shaving and fast load response. GoodWe has paired the inverters with its BAT 100–112 kWh battery and STS 125 kW, enabling UPS-level switching below 4 ms for critical loads. The units were certified by TÜV Rheinland and include AFCI 3.0, RSD 2.0 and a smart DC breaker for enhanced protection. The series operates below 60 dB and supports unbalanced loads and short-term overloading. Up to 15 units were supported through SEC3000C for larger projects.
