The MPPT solar charge controllers are modern, microprocessor-controlled devices which were developed for charging 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. The microprocessor is also responsible for controlling all important protective functions.
