How to test if the charge controller is working
Step 1: Clamp the red battery clip to positive, black to negative and make sure the connection
is secure. Make sure the solar panel MC4 cables are connected to the MC4 cables of the
charge controller.
Step 2: When all the connections are complete, the charging status indicator should light up if
the solar is under direct sunlight AND the battery is connected to the charge controller.
