Quality solar panels are built and guaranteed to produce power for 25 years.
Solar panel shows volts but no amps.
Disconnect your waeco until you can get your charging voltage to above 14 v for some considerable time.
For example if the solar panel is rated at 175 watts and the maximum power voltage vmp is given as 23 6 volts.
To test a 18v solar panel voltage output directly put your solar panel in direct sunlight set your multi meter to the dc volts setting.
Common issues are zero power and low voltage output.
Solar panel volts no amps.
It sounds like you have wired the new panels backwards to the rest of the array.
For that reason it s most likely that a problem is caused by a defect in system.
Below i will describe basic steps in troubleshooting a pv array.
Solar panel produces volts but no amps.
Troubleshooting a solar pv system.
If your solar panel controller also has a regulated voltage output voltage is never more than 12 13v dc then the current supplied to the battery may depend on the voltage that the battery has e g if the solar output is 12 3v and the battery is 12v then the battery is only being charged by 0 3v and the charging current will be small.
This article describes how you can troubleshoot a solar system in basic steps.
If you have not achieved full charging voltages for a considerable time.
Simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black.
Solar panels wired backwards to vs to parallel connections act like a dead short solar panels are just a bunch of giant diodes connect them in the wrong polarity the panels will simply be a large set of diodes connected backwards and take current from the.
Calculate the current in amps by dividing power in watts by the voltage in volts.
Some exceptions may apply based on panel type.
