I'm joining this thread very late. Hope someone is monitoring it. Or, this could move to a new thread.

We've been full time for a couple of months now and the electrical is still a puzzle. I've set up power sharing (took a month to even find out that (I think) it means power available to charge batteries) for 25 amps on one inverter and 5 amps on the other. When we have 50 amps shore power, all is well and we get by fine. This week we have 30 amps. So, for this 30 amp situation, if I turn off both inverters at the remote panel, it seems I get all 30 amps (sometimes more?) to use. The batteries don't seem to get used or charged, so their voltage seems to stay steady.

A curious thing that I do not understand is that when the inverters are on at the remote panel and I turn off the battery charger breakers, then there is no shore power coming through, though the circuits that the inverters can power still work.

Much is still not understood.

Any one interested in any more discussion on this?

Thanks. I sure enjoy all the help here.

Looked at the wiring on Inverters (I have two). Each one has Two AC Inputs - One for Charger and one for Transfer Switch. On each inverter these are tied together and protected by the breaker on my power panel labeled "CHARGER".

If I turn off both CHARGER breakers I have no AC going into Transfer Switch and inverter reverts to INVERT mode thus drawing DC amps from batteries.

Both chargers supply same bank of batteries.

To make thing worse, I'm in a CG with 30A power so, I turned off one CHARGER to keep from blowing breaker. By doing so, there was no AC being supplied to one inverter so it was drawing power from batteries and other inverter was passing AC via Transfer but also charging batteries so I saw DC load on Both inverters. One as a drain and the other supplying charge current.

In conclusion.. with fully charged batteries and both "CHARGER" breakers ON my DC load is near Zero when running MicroWave, Coffee Pot, TV, Fridge and more.

I'm a happy camper now that I know how things work.

Ain't knowlege wonderful?
