Today I went to Carlsbad, CA to install an Overlander Solar Power Kit. The kit includes a 160 watt solar panel, GP-PWM-30 digital Solar Controller, cabling and mounting hardware. The 160 watt solar panel produces 9.14 amps and the digital charge controller monitors the system to prevent over charging the batteries. This kit is available at Sun Power RV. This RV has two new deep-cycle RV/Marine batteries. With just one 160 watt panel and the two batteries, the owner does not have to worry about power unless he wants to run the AC unit (he has an onboard generator for that.) Happy camping!
