This solar power kit includes a dual battery controller to charge the primary and the leisure batteries in your motorhome. Each battery is charged independently of the other. The controller prevents overcharging yet uses no power in standby mode.
The kit includes an 115W solar panel, 20A dual controller, mounting brackets, fixings, cable gland and sealant. (Batteries are not included).
Simple to install. The fixing kit is for permanently mounting the solar panel on the flat roof of your motorhome or narrowboat (or caravan if you have two leisure batteries in use). 
These panels are fitted with high transmission glass and bypass diodes, which means they make the most of sunlight and minimise the effect of shadows.
