GoodWe’s ET Series inverters, available in 40kW and 50kW capacities, are designed for commercial and industrial PV installations. These adaptable inverters seamlessly integrate into both on-grid and off-grid applications, facilitating parallel connections in either scenario. When paired with the Static Transfer Switch (STS) Box from GoodWe, the inverter not only ensures dependable UPS-level switching to backup mode but also interacts with diesel generators to efficiently replenish batteries. Moreover, the ET Series is compatible with diverse battery capacities and brands, including the GoodWe Lynx C, offering a comprehensive energy storage solution.


Superb Safety & Reliability
Type II surge protection on DC side is integrated to protect the inverter from lightning, providing upgraded safety and reliability for the PV system. With an optional Arc Fault Circuit Interrupter (AFCI), the inverter is able to detect arc fault failure, sending alarms through monitoring systems and breaking the circuit simultaneously.

High Generation and Optimized Consumption
The ET Series has been improved for compatibility with high-power modules, with a maximum of 21A input current per string. The 150% DC input oversizing and 98.1% maximum efficiency, drive your inverter to its full capacity to increase your power output in lower solar radiation conditions.
