How To Test A 12v Solar Panel

Then touch the multi meter s black negative lead to your solar panel s negative wire.

How to test a 12v solar panel. The solar charge controller must not limit the current flow during testing. To test solar panel voltage output put your solar panel in direct sunlight set your multi meter to the volts setting and. Disconnect the positive cable that is. Step 3 measure.

Touch the multi meter s red positive lead to your solar panel s positive wire. Disconnect the positive cable between the battery and the panel. To test a 12v panel meters should always be set to the dc voltage area which usually identified by the symbol below. As most solar panels are 12 volts the solar panel test methods are basically the same.

Re connect the solar panel directly to the battery without the regulator. To test the regulator. Set the meter to above 200 vcd to ensure you get the most accurate reading possible. Set the multimeter to 10 amps.

Make sure that the alligator clips are in the right port to find the. You want to choose a voltage range capable of displaying the maximum possible voltage of the panel in open circuit that is when not connected to the battery or charge controller. That being done connect the solar panel to the controller and also the controller to the solar batteries. Measure operating current as described above.

Step 2 measure state of charge. You will want to ensure that you place the positive to positive and negative to negative when attaching your multimeter to the connection on the back of your solar panel.
