5.3 EPS(Off-grid) Block Diagram

X3-Hybrid G4 series inverter has an EPS(Off-grid) function. When the
grid is connected, the inverter outputs go through the Grid port, and
when the grid is disconnected, the inverter outputs go through the
EPS(Off-grid) port.
The EPS(Off-grid) function can be connected to part of the load, Please
refer to the following diagram for the wiring.
If you want to save installation time, you will need an accessory. If you
need a solution, please contact our sales staff.
