Description of functions
The MPPT solar charge controllers are modern, microprocessor-controlled devices which were
developed for charging lead-acid batteries in solar stand-alone systems. The MPPT (maximum
power point tracker) enables you to make optimum usage of the solar power of your solar
modules. The most efficient operating point of the solar modules changes due to factors such as
exposure rate, temperature and the type of solar cells. This optimum operating point
(MPP-maximum power point) is monitored constantly by the internal microprocessor of the solar
controller and is controlled by the MPPT in such a way that your battery is always charged with
maximum power.
When the maximum charge voltage of your battery has been reached, the MPPT solar controller
switches the charging current off.
Adapting the module power to the solar controller
Strictly ensure that the module power match the used solar controller!
If you have a module voltage which is significantly higher than the battery voltage, the charging
current of the battery will be higher than the given maximum current of the module .For example:
A module with 36V and 5A charges a 12V battery with max.15A. this module requires a MPPT
20A.
