SCM40 PWM 40A MASTERVOLT SOLAR CHARGE CONTROLLER: EFFICIENT SOLAR ENERGY MANAGEMENT for BOAT
The SCM40 PWM 40A Mastervolt solar charge controller is designed for reliable and efficient charging of your batteries from solar energy. Suitable for 12V (36-cell panels) and 24V (72-cell panels) installations, it ensures optimal energy management on board your boat and works with all types of lead-acid batteries.
CLEAR DISPLAY AND ADVANCED FEATURES
This Mastervolt charge controller is equipped with a large backlit screen that allows you to easily view essential system parameters, such as photovoltaic power, battery voltage and charging current. The SCM40 model also integrates a dedicated output to directly connect small devices, providing a complete and practical solution for managing your solar energy.
Thanks to its numerous integrated protections (overheating, overload, short circuit, reverse polarity, etc.), the SCM40 regulator guarantees safe and durable use of your solar installation, even in the most demanding marine conditions.
