Integrated industrial microcontroller provides robust, reliable charge control and fast response to changing conditions. Large LCD display shows all parameters and allows easy adjustment, enabling straightforward setup and real time monitoring. Full 4 stage MPPT charging management maximizes energy harvest from solar panels across varying light conditions for efficient battery charging. Built in protections cover short circuit, no load, reverse polarity, and overload, helping protect both controller and connected equipment. Reverse current protection prevents battery discharge when solar input is off, and low heat generation supports stable, long term operation. Use scenarios: - Remote solar installations for telecoms or security systems where reliable charging and protection are critical. - Off grid workshops or field sites with fluctuating sun, to maintain battery health and system performance. - Recreational vehicles or boats with solar setups, providing safe, efficient charging with minimal heat.
