5 Year Extended WarrantySolar Battery Charger 25A SCM25 with MPPT
The 25A MPPT solar battery charger is Mastervolt’s smallest charge regulator. Max PV input 720Watt. Compatible with 12V & 24V battery voltage
Mastervolt SCM25 Solar Battery Charger with MPPT Controller
The smallest but still powerful battery charger from Mastevolt offer the solar installers great flexibility. You do not have to worry about the size of the solar panels, the inexpensive 36, 60cell 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 maximum PV power of 720Wp. It is possible to connect the panels in series which makes the installation more efficient with reduced cable lenght and negligible power loss.
A versatile MPPT regulator
This charger is adaptable to any standard battery voltage 12V/24V. It will charge all types of batteries such as AGM, gel, wet and Lithium Ion. This is really 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, that includes 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 that means it conforms with IP23 rating.
