Welcome to Northern Arizona Wind & Sun
** If you need to charge two separate battery banks at the same time from the same panels, you will need two charge controllers, or one of the new Morningstar dual charge controllers. **
Testing charge controllers: Nearly all charge controller REQUIRE that they be hooked up to a battery in order to operate. You cannot hook up a solar panel to the input and use the LOAD or OUTPUT with no battery connected. Also, if you try to measure the volts or amps on those terminals with no battery, you will not get a valid reading.
** All About Charge Controllers ** - Not sure what a charge controller is, or what type you need, of if you even need one? Then read our Charge Controller FAQ first.
