Attach the meter to the positive and negative terminals on the solar panel and make sure the panel is properly exposed to sunlight.
How to test a solar panel to see if it works.
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.
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.
Ensure that the multimeter is set to measure volts.
As long as the amp meter is rated higher than the solar panel you will be able to measure the output effectively.
Then touch the multi meter s black negative lead to your solar panel s negative wire.
Step 3 measure current.
There are two types of multimeters.
A green light on your inverter means your system is functioning properly.
Angle the solar panel towards the sun.
A red or orange light during daylight hours means there s a system event or fault.
Touch the multi meter s red positive lead to your solar panel s positive wire.
Switched multimeter this type of multimeter manually switches between the ranges to get the most accurate reading.
As most solar panels are 12 volts the solar panel test methods are basically the same.
Set the meter to above 200 vcd to ensure you get the most accurate reading possible.
E marine walks you through testing a solar panel s output to make sure it s performing correctly.
Using a multimeter to test a solar panel a multimeter is a device that you can use to test the voltage and current of any device.
