The MPP solar controller LRM 1218 is a clocked controller that ensures that the connected solar modules always charge optimally regardless of solar radiation, battery voltage and module temperature while the battery is in the main charging phase.
The charging voltages provided are perfectly adapted to the living area battery by means of a temperature sensor and the possibility of setting four battery types.
The starter battery is also charged with a maximum of 2.5A as soon as the living area battery has passed through the main charging phase.
With the SDT bus connection, the solar controller can be optimally integrated into Schaudt bus systems.
For retrofitting older systems, a connection with a suitable analogue signal is provided for displaying the solar currents in the living area and starter battery.
The built-in fan is very quiet and only in operation at high charging power.
