Connecting a solar controller (charge controller) to a battery involves a few key steps to ensure proper charging and prevent damage. Here's a breakdown:
-
Connect the battery to the solar controller first. This is crucial! Most solar controllers need to sense the battery voltage before connecting to the solar panel. Connecting the battery first allows the controller to initialize correctly and protect the battery. Observe the polarity! Connect the positive (+) terminal of the battery to the positive (+) battery terminal on the charge controller, and the negative (-) terminal of the battery to the negative (-) battery terminal on the charge controller.
-
Connect the solar panel to the solar controller. Once the battery is connected, you can connect the solar panel to the controller. Again, pay close attention to the polarity! Connect the positive (+) terminal of the solar panel to the positive (+) solar panel terminal on the charge controller, and the negative (-) terminal of the solar panel to the negative (-) solar panel terminal on the charge controller.
That's it! Connecting the battery first and then the solar panel, while carefully observing polarity, will ensure the longevity of your setup.
