Battery & Inverter Cables & Lugs

Bookmark and Share

Very high currents can flow in cables connecting inverter to the batteries and between the batteries. Cables must be adequately sized to suit the maximum current drawn by the inverter. Low resistance links and tight connections are essential to maintain even use of a battery bank.

In order to minimise the voltage drop between battery and inverter, and so maintain inverter efficiency, cables should be kept as short as possible and be sufficiently sized.
