This customer wanted a simple, low cost, system for maintaining their batteries when their vehicle is not in use. To accomplish this we installed a 160W panel to maintain the house battery and a Trik-L-Start to send current from the house battery to the starter battery. With this, the batteries will remain healthy when the vehicle is not in use for extended periods of time. If the customers decide they want more power for camping off-grid, we can expand the system.
