3. Wiring
(1) Connect components to the charge controller in the sequence as shown
above. Pay much attention to “+” and “-”. Do not insert the fuse or turn on
the breaker during installation. When disconnecting the system the order
will be reversed.
(2) After starting the controller check if the display is on. Otherwise please
refer to chapter 6. Always connect the battery first in order to allow the
controller to recognize the system voltage.
(3) The fuse should be installed as close to the battery as possible. The
recommended distance is 150mm.
(4) Offgridtec PWM Pro charge controllers are positive ground controllers.
Any positive connection of solar, load or battery can be grounded es
required.
NOTE: Connect inverters or other loads with high start currents directly to
the battery and not to the controller.
Please also check the max. charging current of your controller.
