Testing your solar panel is easy.
How to test solar panel batteries.
Solar panel voltage controller input controller output and battery voltage.
Some exceptions may apply based on panel type.
Voltage drops in the negative line.
To test solar panel amperage output put your solar panel in direct sunlight set your multi meter to the dc amps setting.
Solar panel open circuit voltage i e.
To ensure that you don t blow your device s fuse set the maximum amperage sensitivity to well above your expected reading.
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.
A multimeter is a device that you can use to test the voltage and current of any device.
This article describes how you can troubleshoot a solar system in basic steps.
If you need a multimeter you can get the innova 3320 auto ranging digital multimeter here htt.
Common issues are zero power and low voltage output.
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.
Switched multimeter this type of multimeter manually switches between the ranges to get the most accurate reading.
If the light is working the problem you have is with the battery and the battery is likely dead.
Voltage drops in the positive line.
An easy way to check if a battery still has life is by replacing them with regular batteries.
There are two types of multimeters.
All you need is a multimeter.
Troubleshooting a solar pv system.
Quality solar panels are built and guaranteed to produce power for 25 years.
One of the advantages of a flooded lead acid battery is the ability to quickly determine the battery s state of charge.
Panel disconnected from the controller.
Knowing when the solar light batteries are officially dead can be tricky.
Below i will describe basic steps in troubleshooting a pv array.
Using a multimeter to test a solar panel.
Using a hydrometer is still the quickest and simplest way to determine the state of charge of the flooded lead acid batteries in your solar battery system.
Including the solar panels.
Simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black.
