How to test solar panel batteries.

Some exceptions may apply based on panel type. Switched multimeter this type of multimeter manually switches between the ranges to get the most accurate reading. A multimeter is a device that you can use to test the voltage and current of any device. Troubleshooting a solar pv system.

Panel disconnected from the controller. 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. For that reason it s most likely that a problem is caused by a defect in system. One of the advantages of a flooded lead acid battery is the ability to quickly determine the battery s state of charge.

To ensure that you don t blow your device s fuse set the maximum amperage sensitivity to well above your expected reading. Simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black. Using a multimeter to test a solar panel. To test solar panel amperage output put your solar panel in direct sunlight set your multi meter to the dc amps setting.

Set the meter to above 200 vcd to ensure you get the most accurate reading possible. Solar panel open circuit voltage i e. Voltage drops in the negative line. 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.
