Mastervolt SCM25 solar charge regulator 131902500 is based on Maximum Power Point Tracking (MPPT) technology and is an extremely efficient method of charging your batteries with solar energy. Using MPPT, you can charge batteries up to 30% faster than a PWM regulator, with the same number of solar panels. The solar charge regulator is suitable for both 36 cells panels (12V) and 60 cell and 72 cells panels (24V). The Mastervolt SCM25 solar regulator has a robust casing and is protected against condensation in conformity with IP23. It also has built-in protection against overload, high/low battery voltage, overheating, short circuits and reverse polarity, all of which makes it a safe and reliable option for the marine environment. A temperature sensor with 6m cable is included.

The Solar ChargeMaster controller is suitable for all kinds of lead-acid batteries in 12V and 24V. The device features a large display and switchable output with evening / night lighting function. It is safe, user friendly and flexible.
