The standard setting is “Li”. 

The setting of the battery type 

influences the cutoff voltage of 

the controller. If you use a Gel 

or AGM battery, you have to 

change the battery type to GEL.

This setting provides three options in the following order:

OFF: The function is deactivated (default).
Operating time-choice of 1 to 8 hours.
ON: The consumer output remains on for the entire night. 

This function controls the load output only when it is dark (at night). During 

daylight the consumer output remains off. The connected solar module 

records information on the light intensity.
The load is activated once the solar module detects that it is dark.  
Once it becomes light, the regulator deactivates the consumer output 

regardless which illumination duration has been selected. Due to different 

properties of various modules, the twilight threshold cannot be specified 

accurately. An activation delay cannot be set when twilight sets in.

Calling up the default settings (PRE) deletes the 

previous settings and resets the charge controller to 

the factory settings.
The default setting is: SOC Control / Gel Storage 

Battery / Night Light OFF

The auto-test can determine whether the charge 

controller is fully operational and localize all possible 

windows simultaneously. 
The following preparations must be met before you 

can start the text using the menu item. Non-compli-

ance can lead to incorrect test results.

A)  Disconnect the solar module from the charge regulator   

 

(both connections). The battery must be connected.

B)  Connect a small functional DC consumer, e.g. an  

 

energy-saving lamp, to the load output.

C)  Press the right button to manually disconnect the load.  

 

The load symbol no longer appears in the display.

After these preparations, call up the auto-test menu item and continue as 

follows:
D)  Press the right button. The display begins to flash.
