The Electrical Outlets In My Travel Trailer Are Not Working When On 12 Volt Battery.

by Anonymous

The electrical outlets aren’t working when hooked to battery only but works when plugged to 110/120 electrical outlet, why?

I have a 1998 Prowler 22 ft. Travel Trailer.

ANSWER Greetings thanks for submitting your question on our Ask An RV Question Page.

First let me reassure you that there is nothing wrong with your travel trailer. The reason you are not getting 120 volt electricity in your RV when running on battery alone is because you need a 12 Volt To 120 Volt Power Inverter to transform 12 volt DC current to 120 volt AC current.

Power inverters come in all shapes and sizes. Some smaller inverters can be simply plugged into a cigarette lighter socket; others have to be hard wired to the house batteries on the RV. Power inverters are rated by wattage. Depending on what types of appliances you want to run will determine what wattage power inverter you need.

We have some good information on our website on how to determine what size power inverter you need. Please read the answer I gave to this question I Need A Power Inverter For My RV How Many Watts Should It Be? to get more information.

If you decide to get a power inverter and want to install it yourself you may want to read the answer I gave to this question Can I Connect A Power Inverter Directly To My RV's House Batteries?

I hope that this information has been helpful to you.

Happy RVing
