Expansion Panels are ideal if appliances need to be run for longer periods or more appliances than originally anticipated need to be powered.

The Expansion Panel is supplied on our multi-position aluminium rack and is pre-wired so that it can simply plug directly into the supplementary socket provided on the all weather battery box supplied with the DIY Solar Panel kit.

The battery box is already fitted with a charge controller that allows any DIY Expansion Panel to be used without further equipment being needed.
