Generator not powering RV

The minimum wattage needed to start a air-conditioning unit is usually 3000 watts but there can't be anything else at all using power at the time. If this is on an RV there are components such as the refrigerator, water heater, power inverter and house battery charger that will automatically start when the RV is connected to the generator. These may need to be manually shut off sometimes at the main power box.

The battery is not being charged OR is no longer accepting a charge.

The inverter does not charge the battery. An inverter consists of components that first convert the battery's low (12) volt "direct current" (DC) power used to power automotive devices to a higher (120) volt "alternating current" (AC) power that is required by nearly all household appliances to operate properly.

The charging of the battery occurs when either the RV's engine is running and spins the alternator, etc. OR when connected to another charging device - whether it is permanent or portable.

With the RV engine running, there should be about 13.5 - 15 volts, DC on the battery posts or terminals. This voltage is coming fromt he RV alternator and since it is greater than the 12 volt battery, "charges" the battery. If you use a portable charger - that is part of a generator, or plugs into a power port at a camp site, etc. this will charge the battery.

When none of these things is happening, the battery voltage will slowly drop. Once it is at ~10 volts, it is "dead" and will need to be recharged.

The battery will no longer accept a charge if a "cell" inside it has "opened" or "shorted", or if the battery is at the end of its useful life. The battery state can be checked quickly by any mechanic.

I hope this helps & good luck!

I would call or e-mail the manufacturer of the inverter. The dealer or dealers may know the issue but likely the manufacturer will be more help.
Some devices like an inverter will have a smell in the beginning, power supplies are like that. You said that the inverter didn't get hot but smell indicates something is hot.

Sounds like the link between the inverter and the remote is bad. Chaffed wire, broken wire, etc may be the culprit.

You should still have the shorting jumper that came with the Freedom. Put the jumper into the AUX port, and you should now have local control of the inverter. If so, then replace the wiring between inverter and remote.

It sounds like you have some corrosion on the terminals. Remove the batteries and with a good light source look at the springs and plates to make sure there is no corrosion. If there is remove it with crocus cloth. Check the batteries also for corrosion. If you find any remove it the same way. If after cleaning everything the batteries still will not charge get new ones as you probably have one or more which are shorted.

Thanks for using FixYa and for the generous rating.

whenever I run into a memory issue with a portible unit that uses a battery backup I have found battery corrotion on the battery cointacts! also remove the main power source the batteries the wall plug and let it set for several minutes and hit the power switch a few times then retry everything again

Sounds to me like a problem arises when auxiliary batteries are getting charge from more than one source at a time. When unit is plugged in, or generator running, that supplies one source of charge to batteries, when you start the engine, that supplies another. perhaps it's sensing an overcharge condition when this happens, and is warning you that when you put too much charge at once to deep cycle batteries, you may boil them, and cause premature failure. Personally, if it were me, I'd disconnect the charge line from the alternator, and put it on a switch, that I could shut off, and on as needed, and be done with it. When generator running, shut it off. Double check operation of your battery isolator as well. If 2 strong sources start charging those batteries too fast, that's not good. I'd also think about, or discuss with an electronics guy about adding a diode to charge line from inverter/converter, to stop any possible feedback from alternator when engine running. That said, It shouldn't take more than 1/2 hr, to find charge line from alternator to batteries, and put a switch in a convenient spot in unit, to connect and disconnect as needed. Cheap and easy solution.

Yes you can install 2 batteries for your systems and charged by your rv motor or exteranal charger.

Waeco manufacture a rooftop A/C with a matching inverter.you will need to ensure that you have enough battery power when staionary but your al;ternator will provide power when mobile you could also use a small generator through a battery charger to keep your batteriesd charged up but this is not neccessary unless you are stopped for a long period of time.these units are fairly easy to install and come with fitting instructions for the A/C and wiring kits for the inverter..hope this helps

Are you still under warranty with your RV? If so, take your RV back to them and try to get this problem fixed through them. You know more about electronics than I do (LOL) however, I do believe the RV sales/repair should be taking care of this issue for you.

I on the other hand own the Majestic brand washer and dryer and I am very dissapointed with them. The washer is broken already and is only 15 months old. Ugh!

Good luck, I hope your issue is a simple fix.
