Turn on the charge controller and allow it to initialize. Most controllers have a display that shows battery status and charge levels. If your controller is programmable, set up the charging preferences according to your battery type and needs. Once this step is complete, you’re ready to connect the solar panels.
If you connect the solar panel to a charge controller first, it may not initialize correctly. After you''ve connected the charge controller to the battery, it is now safe to connect it to the panels. Out of the junction box of a panel come two cables, a positive and a negative.
Screw the wires tightly into the charge controller Turn the charge controller on: it should be able to measure the charge of the battery. In the user manual of a charge controller, there should be a wiring diagram, which you can consult if in doubt. It’s advised to wire the controller to the battery first before connecting it to a solar array.
Connection sequence is critical for equipment safety – Always connect batteries to charge controllers before solar panels. This prevents controller damage and ensures proper system voltage detection, as charge controllers use battery voltage as their reference point.
