STECA PR1010 S0LAR CHARGE PWM REGULAT0R / C0NTR0LLER
This is a true quality unit. German made. I started using solar years ago. KINGS was the controller of choice (cheaper the better back then) but they ruined many trips away as they always failed which killed my battery and it caused me to lose all my food. Frustrating as hell, I started looking for a quality unit and after many weeks searching and reading up there was only 1 unit out there that had a 100% issue free reviews. I ordered 1 (they were very expensive) and everything just worked.
