It looks like I have 4 6v house Batts in pairs so I will replace with similar to ease the installation

I would guess that your converter or inverter/charger is not charging your batteries, or they would not have reached this condition (although it could also be overcharging and boiled all the water out). I would suggest you check the voltage across the batteries while plugged into shore power. It should be somewhere in the range of 13.2 to 13.6 volts when they are fully charged (maintenance charge) but might be up to about 14.5 volts when charging up. A voltage in the 12.7 volts or lower will show that whatever is supposed to charge them is not working.

No.

AC for example does not.

Did you check the "Ground Fault Indicator" for tripped? It is "normally" in or near the bathroom.

On my coach the incoming shore 120VAC, (or generator 120VAC) "passes through" the inverter, (and through 2 120V circuit breakers on the inverter), on it's way to many, (but not all), of the house recepticals.

FWIW I would find that quite interesting. I seldom disagree with twinboat as we tend to think the same way. If your setup runs the Air Conditioning through the Inverter that means you could theoretically use the batteries to run the Air Conditioner. Not a very good idea. Probably why most units with big inverters split the load before the Inverter. That concept had me thinking "maybe" about what he said so I added my comment. I would physically check it to make sure what is really happening. OTOH I can see why it might be done.

Well that is confusing.

That seems you are saying that ALL AC goes to the invertor first.

Then you say:

That seems you are saying "some" 120 outlets are not from the invertor = not ALL AC goes through the invertor.

I am also confused why IN AC would go through an invertor. What is the invertor doing to the AC? Nothing? Just passing it through? Providing circuit breakers only?

If you have a invertor/battery charger combo, I could understand an AC in to the unit, otherwise what is the point.


I would be interested in seeing a wiring schematic of the coach.


Confused.

I never said all AC goes thru the inverter, but on most, some does. How much and to what, is up to the builder or installer.

I don't know what Mel has.

Confused.
because the AC-IN on your inverter is actually the input to a transfer switch. With power applied to the AC-IN, it is passed through. When NO power exists on AC-IN, the inverter will produce it's own version of 120vac and send IT down the line. That connection is valid even though there is no charger involved with that type of inverter.

IF Mel's 120vac shore power/gen power goes through the inverter transfer switch, before it goes through the main breakers, he must have a non-factory installed system. That arrangement is not the usual.

As you say: not all shore, or generator, AC power "passes through" my inverter.

On my Heart Freedom 20 inverter, 120VAC shore or generator power "passes through" the inverter, (and therefore through the 120V breakers on the inverter), ONLY to the receptacles that can be powered by the inverter.

Any receptacles that are not wired to operate on inverter power, (as well as the 2 rooftop A/C units), do not get power through the "inverter pass-through".
To use those receptacles, and/or the roof A/C units, I have to have shore or generator 120VAC power.

On my coach NO 120VAC power goes TO or THROUGH my Heart Freedom 20 inverter before it goes through the main breakers.

Thanks for clearing that up, Mel.
A couple of the folks sounded confused on that issue.

FWIW If you go back and look there is some confusion in the first posts. At least part of it is differentiating between AC as in Alternating Current and A/C as in Air Conditioning.
