This client requested as much solar power as possible. We ended up installing 640W of solar power within the limited space available on their roof. We also installed a Trik-L-Start charger which takes power from their solar charged house batteries and transfers it to the starter battery. The Trik-L-Start charger is particularly useful when the vehicle is parked for extended periods of time. You won’t have to worry about your starter battery dying, and it helps maximize the life of the battery.
