The vehicle is charging a 6S 8Ah LiPo with 600W solar panels. The Lipo is powering a UPS that is switching up the voltage to 230V that is powering the PA-system.

Because the solar regulator is designed for lead-acid battery’s  over-voltage is a big issue. Ordinary LiPo-checkers don’t check for over-voltage, so we had to design our own out of a IntroARM.
