(Off-grid)
The 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, and it can also
be used to connect to all loads. Please refer to the following diagram for the
wiring .
To be compatible with all loads, you will need an addition a accessory. If you
need a solution, please contact our sales.
For to different local wiring rules, please refer to the diagram below
Please select the appropriate wiring method according to local wiring rules.
Diagram A: Neutral line and PE line are separated from each other, and the

Diagram B: Neutral line and PE line are separated from each other,
all loads connect to the EPS(Off-grid) port; (For most countries)
Diagram C: Neutral line and PE line are combined together, and the
