lost all power on 4th day : Clueless as to cause!

A typical 6 gallon water heating element is 1400 watts (seen on Amazon). A full size Escape-provided inverter is rated at 2000 watts. On paper it will work just fine - until the batteries are flattened. That should happen within a few hours and be difficult to overlook. So no, not likely the cause if the OP went 4 days.

What I'm saying is - the dual mode water heater only works on AC with shore power. The inverter option either works on one dedicated outlet or to all AC outlets with a transfer switch option. That doesn't include the water heater.

And to my knowledge Escape doesn't wire any appliances to the inverter, only the outlets. But, if the inverter was a DIY or aftermarket install all bets are off.

Edit: the microwave plugs into an outlet that is wired. And the refrigerator plugs into an outlet that isn't wired.

Admittedly nit-picking...Escape installed inverters are 1500 watts.

I like most I suspect, am not crazy about CPAP use, but my relationship with my wife significantly improves.

Perhaps this info will be helpful for you for comparison- We have dual lead acid 6v batteries and I use an Airsense 10 CPAP. We recently returned from a 5 day trip to CO mountains camping and the weather was mixed clouds, sun and rain on and off, so not great solar charging weather. It was cool at night and our furnace ran multiple times each night, Contrary to expectations and despite what others have said, I have never been able to get my Airsense 10 to run off batteries (whether the trailer batteries or a seperate 12v battery pack) using a 12-24v DC-DC converter. My solution has been to run the unit as you did, plugged into 110v outlet using the inverter.

Each morning, the batteries would be down to 12.6 v from fully charged but I did not see a reading below 12.6v. We were very careful with battery usage in the evening before bedtime and even used battery operated lanterns for reading, etc. My experience with this same CPAP machine that you have makes me think you had some other issue that brought down your lithium batteries.

All I can figure is you must have a problem with your Air Sense 10, the same model Beth has which we use the converter for successfully. Even if the solar readout of voltage and charge state is inaccurate had we drained the lead acid batteries then we'd have know about it when they could not be recharged.

I'm quite ignorant regarding electricity but with the reading I've done on this forum I would think that using the 110v inverter to plug in the CPAP would use more power, i.e. DC-AC-DC than just using DC upping it to 24v with the converter.

For the OP's question about how to plug in the converter it comes with a standard cigar lighter style plug so just use one such outlet in the trailer if reachable. We were fortunate that the previous owner had one 12v outlet installed at the foot of the bed on Beth's side.
