SCM25 MPPT
The SCM25 MPPT is Mastervolt's smallest MPPT charge controller and just as powerful as its big brother. With 200 to 700 Wp on solar panels, switchable output and buzzer, this Solar ChargeMaster is well suited for small to medium sized systems.

Innovative technology in Mastervolt MPPT charge controllers increases the efficiency of solar panels. The SCM25 MPPT charges your batteries up to 30% faster than PWM regulators, with the same number of panels.

MPPT charge controller for all solar panels
In addition to traditional 36 and 72 cell panels, the SCM25 MPPT is also ideal for economical 60 cell panels. High PV voltage allows multiple panels to be connected in series, which significantly reduces cable length, installation time and power loss in solar cables.

Easy to use, secure and flexible
The SCM25 MPPT is suitable for all battery types, including Mastervolt Lithium Ion. Charge profiles for all types of batteries are pre-programmed and can be selected at the push of a button. The SCM25 MPPT is quiet and equipped with a clear and very easy to use display. Built-in protection against overload, high/low battery voltage, overheating, short circuit, and reverse polarity ensure safety comes first. In addition, the SCM25 MPPT has a robust housing and is protected against condensation in accordance with IP23.
