Do not skimp on your wiring across your solar installation. Pushing too many amps across a wire that is too small can cause fires and short your installation - this is dangerous!

A rightly sized wire reduces resistance and can assist with reducing voltage drop.

For example, in my system i have a 1000W inverter attached to my 24v battery. If i’m pulling 1000W, then amps 1000W / 24V = 41.67A. Meaning i should be using a 6 gauge wire (see below) between my battery and inverter.
