 MPPT (Max Power Point Tracking) makes optimal use of the full power of your solar modules.

For all common module technologies, optimal for solar systems with module voltages that are higher than the battery voltage.
With these controllers you can also use modules that are actually intended for use in grid-connected systems.

The most efficient working point of the solar modules changes due to various factors, such as module temperature, irradiation, module type etc. This working point is constantly monitored by the internal microcontroller and, if necessary, controlled in such a way that the optimal performance of the solar module is given and your batteries are charged with the respective greatest current ,

Lead-acid, maintenance-free lead-acid, lead-gel and lead-fleece batteries are generally used in photovoltaic solar systems to store the energy. Lead batteries must be protected against deep discharge and overcharging. The MPPT solar charge controller meets both requirements, and the batteries are also well maintained by intelligent maintenance.
The switching thresholds for over / undervoltage, load cut-off and reset voltage are controlled precisely and temperature-stable via the internal microcontroller. These sound thresholds can be freely selected in the user battery type and can be programmed using PC software.


The controller can be monitored and set using the MT50 display or adapter cable and software. The controller can be monitored using the PC software.
4 types of batteries can be set. In the user battery type, the voltages are freely selectable and programmable via the software (lithium batteries).

A switchable load output gives the user the option of switching all consumers connected to the solar charge controller on or off at the press of a button on the controller or via software settings on the PC.
The load output (Load) switches off in the event of undervoltage. As soon as the voltage has reached a safe point, the load output switches on again.

2 timers can control night lighting as soon as the controller detects "night" through the solar module.
Yield measurement of all system parameters and monitoring via PC software possible.
The controller can be set and monitored with the optionally available MT50 display.
