Product Description
The Goodwe ET Series is a three-phase high voltage energy storage inverter that enables enhanced energy independence and maximizes self-consumption through an export limit feature and time of use shifts for reduced electric bills. Covering a power range of 5 kW, 6.5kW, 8 kW and 10 kW, the ET Series allows up to 10% overloading to maximize power output and features Uninterruptible Power Supply Function (UPS) to inductive loads such as air conditioners or refrigerators with an automatic switchover time of less than 10 milliseconds, providing savings when the grid is up and independence and security when it is down or compromised.
