Maximum Power Point Tracking (MPPT) function.
Maximum Power Point Tracking, frequently referred to as MPPT, is an electronic system
that operates the Photovoltaic (PV) modules in a manner that allows the modules to
produce all the power they are capable of. The Solarmate Charge controller is a
microprocessor-based system designed to implement the MPPT.And it can increase
charge current up to 30% or more compared to traditional charge controllers.

Solar changer function
There is a solar charger built in, List below is the spec for solar charger
NOTE:The optional battery temperature sensor automatically adjusts the charging process of the
controller according to the type of the battery is selected by user through battery type selector.
With the battery temperature sensor installed, the controller will increase or decrease the
battery charging voltage depending on the temperature of the battery to optimizethe charge
to the battery and maintain optional performance of the battery.
