How To Test Solar Panel Regulator

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.

How to test solar panel regulator.

Disconnect the positive cable that is. Some exceptions may apply based on panel type. To test solar panel amperage output put your solar panel in direct sunlight set your multi meter to the dc amps setting. As most solar panels are 12 volts the solar panel test methods are basically the same.

Solar panel voltage controller input controller output and battery voltage. I recorded current three times during testing and calculated the average. Set the multimeter to 10 amps. The diagram shows a typical iv curve for a 60w solar panel which plots the behaviour of its voltage horizontal axis and current vertical axis left.

Measure the operating current by connecting the ve from the multimeter to the positive. Testing solar panels for volts to test solar panel voltage output put your solar panel in direct sunlight set your multi meter to the volts setting and. Voltage drops in the negative line. Panel disconnected from the controller.

Solar current should be constant. In doing so the battery pulls the solar panel down to its voltage let s take a typical 12 5 volts for the battery voltage. Testing the voltage simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black. Touch the multi meter s red positive lead to your solar panel s positive wire.

That being done connect the solar panel to the controller and also the controller to the solar batteries. To test the regulator. To ensure that you don t blow your device s fuse set the maximum amperage sensitivity to well above your expected reading. The blue line also shows power output in watts vertical axis right.

Solar panel open circuit voltage i e. Re connect the solar panel directly to the battery without the regulator. Set the measurements of the multimeter to dc amps. 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.

Set the meter to above 200 vcd to ensure you get the most accurate reading possible. Disconnect the positive cable between the battery and the panel. Make sure that the alligator clips are in the right port to find the.
