DC Wiring recommendation

It is suggested the battery bank be kept as close as possinle to the inverter. The following cable is a suggested wiring option for 1 meter DC cable.

Please find the following minimum wire size. In case of DC cable longer than 1m, please increase the cross section of cable to reduce the loss.
