5. Grounding the Solar System
Solar Panel
Battery
DC Output
Be aware that the positive terminals of the controller are connected internally
and therefore have the same electrical potential. If any grounding is required,
always do this on the positive wires.
Note :
If the device is used in a vehicle which has the battery negative on the
chassis, loads connected to the regulator must not have an electric connection
to the car body. Otherwise the low.
6. Starting up the Controller
Self test
The charge controller starts a self test when it is properly connected to the
battery and solar panel. After which the display resets to normal operation.
System Voltage
The controller adjusts itself automatically to 12 V or 24 V system voltage. As
soon as the voltage at the time of start-up exceeds 18 V, the controller implies a
24 V system. If the battery voltage is not within the normal operation range ( ca.
12 to 15.5 V to ca. 24 V to 31 V ) at start-up, a status display according to the
section ERROR DESCRIPTION occurs.
