My Solar Panel Will Not Charge 24v Battery

How do we tell if the solar panel is charging the batteries on our 2002 motorhome.

My solar panel will not charge 24v battery.

For 24v trolling motor batteries it becomes even more difficult to recharge the battery pack with a solar panel. Match up the male and female connectors with the opposite ones coming away from the solar panel and snap the mc4 connectors into place. Gary bunzer aka the rv doctor re. You can get the amount of energy it will provide the battery by multiplying 10 watts by 6 hours which will give you 60 wh.

This means that the panel is not connected to either a battery or a charge controller. Deb from gilbert ariz wants to know. If you have added extra wire or an extension to your lead wires you can measure the voltage at the end of these. An important point to be noted here is that a 24v rating battery is not available in the market but you can create one by joining two 12v batteries in a series connection.

Generally a 12v solar panel should be paired with a 12v battery and a 24v solar panel should be used with a 24v battery. So a 24v 140 watt solar panel at minimum up to a 24v 300 watt solar panel ideally is what would be needed. If you are using a group 27 to 31 battery you need a panel double the wattage of the 12 volt solar panels mentioned above. This means that on that scenario the solar panel delivered 60 watts of power to charge the battery.

So if you have a solar panel that with a 10 watts power rating and it is exposed to sunlight for at least 6 hours. If you did provide 24 volts to the charge controller how much voltage will it apply to the battery which is important because 24 volts is probably too much. Connect the wires from the controller to the solar panel. Your panel is rated at 12 volts and 5 watts.
