The SCM25 MPPT is Mastervolt’s smallest MPPT charge regulator and just as powerful as its big brother. With 200 to 700 Wp in solar panels, switchable output and buzzer, this Solar ChargeMaster is very well suited to small and medium systems.
The innovative technology in the Mastervolt MPPT charge regulators increases the efficiency of the solar panels. The SCM25 MPPT charges your batteries up to 30 % faster than PWM regulators – with the same number of panels.
SIZES & DIMENSIONS
SCM25: 398 x 168 x 104 mm; 15.7 x 6.6 x 4.1 inch
SCM60: 135 x 190 x 75 mm; 5.3 x 7.5 x 3.0 inch
WHAT'S IN THE BOX
FEATURES
MPPT charge regulator for all solar panels
Besides the traditional 36 and 72-cell panels, the SCM25 MPPT is also ideal for the inexpensive 60-cell panels.
Easy to use, safe and flexible
The SCM25 MPPT is suitable for all battery types, including Mastervolt Lithium Ion. The charging 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 very user-friendly, clear display. Built-in protection against overload, high/low battery voltage, overheating, short circuits and reverse polarity ensures that safety comes first. Moreover, the SCM25 MPPT has a robust casing and is protected against condensation in conformity with IP23.
