The controller can be monitored and adjusted with the MT50 display or adapter cable and software. The controller can be monitored via the PC software.
There are 4 battery types adjustable. In the battery type user the voltages are freely selectable and programmable via the software. (lithium batteries)
A switchable load output enables the user to switch on or off all loads connected to the solar charge controller with one keystroke on the controller or via software settings on the PC.
2 timers can control a night lighting as soon as the controller detects “night“ by the solar module.
Yield measurement of all system parameters and monitoring via PC software possible.
With the optionally available display MT50 the controller can be adjusted and monitored.
