ES Series

Hybrid Inverter

The Goodwe ES series bi-directional energy storage inverter can be used for both on-grid and off-grid PV systems, with the ability to control the flow of energy intelligently.

During the day, the PV array generates electricity which can be provided either to the loads, fed into the grid or charge the battery, depending on the economics and set-up.

The electricity stored can be released when the loads require it during the night, including inductive loads such as air conditioners or refrigerators.

Additionally, the power grid can also charge the storage devices via the inverter. An all-round intelligent system for maximum energy flexibility.

Charge controller and inverter integrated.

*1 : Lead-acid battery use refers to Approved Battery Options Statement.
The actual charge and discharge current also depends on the battery.
*2 : Under off-grid mode, then battery capacity should be more than 100Ah.
*3 : When there is no battery connected, inverter starts feeding in only if string voltage is higher than 200V.

*4 : 4600 for VDE 0126-1-1 &VDE-AR-N4105, 4950 for AS4777.2(GW5048D-ES); 4050 for CEI0-21(GW3648D-ES).
*5 : 21.7A for AS4777.2
*6 : Can be reached only if PV and battery power is enough.
*7 : The standard configuration is CAN.
