Review on SUNER POWER Waterproof Battery Maintainer RV Parts & Accessories by Chris Wagner

Got this 24V/20W solar charger with built in charge controller. It seemed to work fine for a few days. My gate slowed down and eventually stopped working. The battery was below the operating parameters. As a backup, I connected a charger to service electric batteries. Will not work. I then transferred this solar panel to my mower and hooked it up to the mower and my motorbike, the solar charger showed "reverse polarity". It is obvious that this panel is defective. I asked for a return and exchange. Received today, will check tomorrow
