Installation Notes
The inverter supports a maximum battery charge and discharge current of 140A.
Each battery port supports up to 70A using 25mm² cable. Where the full 140A is required from a single battery stack, battery cables must be connected to a common positive and negative busbar, with a 25mm² cable run to each battery port.
Battery settings should be configured to 1 BAT 2 DC with the BMS connected to port 1.
