My Solar Panel Will Not Charge 24v Battery

Deb from gilbert ariz wants to know.

My solar panel will not charge 24v battery.

How do we tell if the solar panel is charging the batteries on our 2002 motorhome. Generally a 12v solar panel should be paired with a 12v battery and a 24v solar panel should be used with a 24v battery. 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. Your panel is rated at 12 volts and 5 watts.

This means that on that scenario the solar panel delivered 60 watts of power to charge the battery. For 24v trolling motor batteries it becomes even more difficult to recharge the battery pack with a solar panel. Once you ve attached the input wires to the charge connector you should have 2 loose wires each ending in an mc4 connector. Gary bunzer aka the rv doctor re.

Connect the wires from the controller to the solar panel. Thus assuming it is getting sufficient sunlight its maximum current is 0 42 amperes. Match up the male and female connectors with the opposite ones coming away from the solar panel and snap the mc4 connectors into place. 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.

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. 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. Depending on your solar panel size and type your lead wires can end on either bare wires or a quick connect plug as the ones as the ones shown.
