To test solar panel amperage output put your solar panel in direct sunlight set your multi meter to the dc amps setting.
How to test a 6 volt solar panel.
To ensure that you don t blow your device s fuse set the maximum amperage sensitivity to well above your expected reading.
Results will vary depending on sun strength time of day angle of light and temperatu.
Then run wires from the battery to the charge connector making sure to match the positive and negative poles.
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.
As long as the amp meter is rated higher than the solar panel you will be able to measure the output effectively.
To charge a battery with a solar panel connect a charge connector to the solar panel.
Attach the meter to the positive and negative terminals on the solar panel and make sure the panel is properly exposed to sunlight.
Step 3 measure current.
All you need is a multimeter.
If you need a multimeter you can get the innova 3320 auto ranging digital multimeter here htt.
How to test a 12 volt solar panel vs other voltages.
Simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black.
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.
As most solar panels are 12 volts the solar panel test methods are basically the same.
Divide the wattage of the solar panel by the voltage of the battery to get the number of amps your charge connector needs to handle.
Testing the 12 volt solar panel.
The solar panel will trickle charge your 6 volt battery during the day.
Some exceptions may apply based on panel type.
