Dead House Batteries

[rmchipmanhughes]

First Time Posting:

RV has been plugged in to house power for several weeks.
Inverter shut down (blinking red) due to low voltage in house batteries.
Now ac will not run even with shore power still hooked up.
I appreciate your help!

Thank you,

Welcome to the forum.

If the RV is plugged into shore power and is actually getting shore power (circuit breaker didn't trip and you're actually not getting power to the RV) then there is probably an issue with the converter. The CONverter (different than an INverter) is going to distribute the A/C electricity as well as convert A/C to D/C for charging the batteries and powering other D/C powered items (lights, thermostat, refrigerator controls, etc.).

As mentioned the first thing to check is that you are actually getting shore power into the RV. If you are then check the converter D/C output voltage using that voltmeter you mentioned across the wires connected to the battery terminals. It should be ~13.6V. Since the batteries are dead it's likely you're not getting proper charging voltage but it should be checked anyway just to insure whether the converter is the problem or not.

Hi Marilyn,

Welcome to the forums.

The roof air may require a good 12 volt source for the control boards.

Start by checking the shore power. Make sure there is power.

If there is, then check the output of what ever device charges the battery bank.

The Inverter model is a Tripp Lite 612
It has 6 (six volt) house batteries wired in series/parallel

My husband is a DIY'er but has limited electrical experience but can use voltmeter and test light.

First why not post what make - model of inverter/charger you have.
If you tell me you don't know, then please start looking for it.

Some people like to know the make and model of the Rv you have also.

Example, my MH has a Xantrex Inverter AND charger combination unit. I also have a inline fuse to the inverter/charger batteries.
I need to plug in or run the generator for it to operate.
It can run on generator but not work on shore power due to a bad automatic transfer switch (ATS).
Now I can go on. but please think about this, for me, I need additional information to help. Others may chime in, but I do believe we all need additional info.
And finally, are you a DIY'er, able to use a voltmeter and limited tools? If not, then you really need to call someone who can, to help you.

Thank you Mike, I will check the circuit breakers.
