Ø Grid port connection
The 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.
For to different local wiring rules, please refer to the diagram below
Please select the appropriate wiring method according to local wiring
rules.
