Description
3.1 Functions
The solar charge controller
monitors the battery voltage,
controls the charging process,
controls the connection/disconnection of loads connected to the load output.
This optimises battery use and significantly extends its service life.
A battery charging algorithm protects the battery from harmful states. Activa-
tion of the three deep discharge functions (LVW, LVD and LVR) is dependent
upon the battery voltage.
3.1.1 MPPtracking
This solar charge controller meets the latest technological standards since it is
equipped with an optimal MPP tracking algorithm and thus can use at all times
the maximum available output of the solar module. You will find more detailed
documentation about MPP tracking in the technical manual; which can be ac-
cessed at www.stecasolar.com.
3.1.2 WhatisMPPtracking(MPPT)?
MPPT stands for "Maximum Power Point Tracking". This describes a process by
means of which the solar module is always operated at the point of maximum
possible power. Because the point the maximum power can vary depending
on the operating mode and the local conditions, and because it changes in the
course of the day, the term "tracking" is used, i.e. the tracking of this point.
