Touch the multi meter s red positive lead to your solar panel s positive wire.
How to test a 12v solar panel.
Testing a small 12v solar power system step 1 wait for a clear sunny day.
Disconnect the positive cable that is.
The solar charge controller must not limit the current flow during testing.
Set the meter to above 200 vcd to ensure you get the most accurate reading possible.
To test solar panel voltage output put your solar panel in direct sunlight set your multi meter to the volts setting and.
Step 3 measure.
Set the multimeter to 10 amps.
Then touch the multi meter s black negative lead to your solar panel s negative wire.
As most solar panels are 12 volts the solar panel test methods are basically the same.
To test a 12v panel meters should always be set to the dc voltage area which usually identified by the symbol below.
The system should be tested at maximum current with the solar array in direct.
Disconnect the positive cable between the battery and the panel.
Re connect the solar panel directly to the battery without the regulator.
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.
Measure operating current as described above.
Set the measurements of the multimeter to dc amps.
Make sure that the alligator clips are in the right port to find the.
Step 2 measure state of charge.
