battery charging

We are staying in a campground that has no hookups, therefore we are having to run on our batteries. We have an 09 40' Phaeton with a commercial frig with 6 house batteries. No problem with charging the batteries with the house generator; however, when I try and charge the batteries with a 2000 Honda the batteries will not charge. I have tried running the Honda through a ground fault and it gives me a caution when flashing indication. The ground fault was working properly last week when we had the coach plugged into a 110 outlet. I also removed the ground fault and hooked the coach straight to the Honda and the system status in the coach would still show inverting. Questions: 1) Is a Honda 2000 big enough to charge the batteries on a coach this size? 2) blown fuse somewhere? I have checked the reset on the Honda. Thank You! John

Simple solution. 50 foot extension cord and a decent brand battery charger.

Depending on your inverter/charger's size (how many amps of charging available), you may have to go in and reduce the amps of 120 VAC it can use. Often called "power share/power save". This can be done in a few seconds from your inverter/charger remote.

Obviously, verify that all other 120 VAC loads are OFF. If residential refrigerator tries to start and inverter/charger is in high-amp bulk mode, you may be exceeding the Honda's capability. If this happens, might turn off the refrigerator breaker until charge amp rate tappers off a little.

It is big enough but something in your coach does not play well with the Honda.

I have seen this issue but did not get to pursue the resolution. Something with the ground etc.
Not much help but the 2000 is plenty to charge things. You need to turn AC's off of course and put the HWH on propane to keep the load down.
