You will next connect the solar panel to the controller as well as the controller to the battery. That being done connect the solar panel to the controller and also the controller to the solar batteries. Check both manuals the battery manual and the controller manual and make sure that the controller is set for the proper battery agm wet cell etc and temperature lead acid batteries are very sensitive to change voltage and battery temperature. How to test a solar panel voltage and current duration.

Make sure that the alligator clips are in the right port to find the. Simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black. Open circuit voltage can vary depending on your solar panel but the readings we are usually looking for are in the range of 15 to 23v. Measure the voltage between the ve and ve terminals by connecting the negative contact from the voltmeter to the negative on the panel and the positive contact on the voltmeter to the positive on the panel.

Set the meter to measure dc amps and make sure that the leads are in the right port to measure dc amps.
