Description
xThe 25A MPPT solar battery charger is Mastervolt’s smallest charge regulator. Max PV input 720 watts. Compatible with 12V & 24V battery voltage
The smallest but still powerful battery charger from Mastevolt offers solar installers great flexibility. You do not have to worry about the size of the solar panels, the inexpensive 36, 60-cell or 72-cell photovoltaic modules are compatible with the SCM25 charger. What is more important, the innovative controller will charge your batteries up to 30% faster than any other PWM regulator.
EASY CONNECTION TO SOLAR PANELS
The SCM25 can be connected to a maximum PV power of 720Wp. It is possible to connect the panels in series which makes the installation more efficient with reduced cable length and negligible power loss.
A VERSATILE MPPT REGULATOR
This charger is adaptable to any standard battery voltage of 12V/24V. It will charge all types of batteries such as AGM, gel, wet and Lithium Ion. This is achievable because Mastervolt has pre-programmed the charging profiles for all major batteries. The user can select his battery using the buttons on the controller.
SAFETY COMES FIRST
There are loads of protection features for safe and trouble-free operation, including protection against overload, high/low battery volts, over temperature, short circuit and last but not least reverse polarity protection. The housing of the battery charger will protect the electronics from condensation which means it conforms with IP23 rating.
