Care

The sun as an extra energy source. This solar charge regulator based on PWM technology is a great solution to charge your batteries with solar energy. Suitable for both 36 cells panels (in 12 V systems) and 72 cells panels (in 24 V systems). Its protection against water spray, suitability for high ambient temperature and compatibility with negative grounding, make it the perfect solar regulator for marine and mobile environments
