 SCM25 MPPT Solar ChargeMaster 
 
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. 
 
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. The high PV voltage makes it possible to connect 
several panels in series, significantly reducing the required cable length, 
installation time and power loss in solar cables.  
 
Easy To Use, Safe & 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.
