Turning off converter and still allow 110V to work

Was wondering if I can turn off the converter while plugged into shore power. Do not need 12V or charge the batteries. I would like to put a small 110V heater inside without trying to find a way to fish an extension cord. I assume there is probably a breaker for the converter (WFCO 8955)

I appreciate the info

Without the converter charging the batteries they will discharge and your frig and fans and some other items will not work until you get the batteries back up to power. Just plug the heater into one of the electrical outlets.

Why do you even want to shut it off?

We think you do need 12v for things like lights and control board for refrigerator and possibly TV antenna amp and in many rigs even the radio/dvd player-- all 12v.
Once batteries are fully charged the converter is pulling very little power.
If you are looking for more amps for a space heater you can shut off the electric heater in your water heater and heat water with LP. You could even put
the fridge on LP only.
Are you having problems with a tripped breaker??
Why do you want to shut off your converter?

is this so you can store the rv with a heater running, but don't want the converter to cook the batteries?

1) I'd disconnect batteries and leave the 12 volt system on if your batteries hold a charge. However, it won't hurt you batteries to leave them connected.
2) Usually you do not want to have a space heater on an extension cord.
3) I don't see the relationship between the 12 volt system and not wanting to fish an extension cord?! 110v heater? 12 volt converter. I would suspect most of your inside lights are 12 volt and you need the converter to supply the 12 volt power. If you disconnect the converter you will be powering off the batteries. Which you need to keep charged.

I'm pretty sure you need 12 volts more than you realize. Lights for sure.

And CO /LP detector.

Probably also fridge logic board and heat/A/C thermostat.

As far as I know there is no "switch" or fuse you can pull to kill just the inverter but keep the 110v on because they are directly integrated.

Yes- I have the batteries disconnected at the neg post... My solar will keep them maintained. I just want to put a heater in the rig and plug it into one of the interior 110V outlets.. I have her buttoned down and there are no gaps to bring in an extension cord and would rather use the main umbilical cord. no need to have the converter running. I think there is a breaker for it on the panel. I just need to get to the MH to have a look.

I live in an area with snow and ice. (could affect my solar panels) I may also hook up a maintainer and would like to plug into the 110 outlet inside the MH

thx for all the responses

Hey Turbs, good question. Batteries are disconnected and I do not require any 12V in the unit until I take her out next year.. was worried about having a converter active with no load and no batteries connected. Perhaps converters are low risk for faults or burnouts and I have nothing to worry about

now I'm more confused. Why is it plugged into shore power and you need 120 volt if you aren't camping till next year?

I was worried about a converter running with no load on it or connected to batteries. Meanwhile I wanted to have 110 v heat and run some power tools as I do a few mods inside the MH. However, I just received an email back from WFCO saying it is OK to let the converter run even though it is not connected to a battery or the 12V is not being used.

again I appreciate all of your feedback

I leave my unit plugged in 24/7 365.
Converter "4 stage" is also up and running and charging batteries.
More often then not my whole system is drawing 1 amp when I look @ the ems panel.

OK I think I understand. You live were it is COLD and you just want to run the 120v heater to keep it warm inside the camper and the batteries are not going to be used to run the lights, fridge, or fans.

So if you don't want the converter to run...pull the fuse (on the converter) out and it will not try to charge the batteries nor will you be able to use the lights, fridge, or fans unless you put the fuse back in. Mine has 2 fuses.

On our Solera the converter is on one of the circuit breakers. Turning off that breaker would turn off the converter (and, in my case, one 110 volt outlet that is on the same breaker) and would leave the rest of the 110 volt circuits on.

I would do as Turbs and just leave things alone and allow the converter to maintain the batteries. No sense in having another charger to do what the converter is already doing. If there is no (or minimal) draw on the system, the converter (fan) won't be running, at least until the battery needs a top off. That's what it's made to do, let it do it.

Just wait till the furnace (12 volt powered) won't come on.
