When considering how to set up a solar charge controller, remember there are only four connections required: one positive wire running from the solar panel to the charge controller, one negative wire also running from the solar panel to the charge controller, and another two wires running from the controller to the battery bank.

What does a solar charge controller do?

What a solar charge controller does Think of a solar charge controller as a regulator. It delivers power from the PV array to system loads and the battery bank. When the battery bank is nearly full, the controller will taper off the charging current to maintain the required voltage to fully charge the battery and keep it topped off.

How to choose a PWM controller for a solar panel?

For PWM controllers, focus on the battery voltage and the controller's current rating. The voltage of the PWM controller should be the same as the battery's, just like for MPPT.
