CPAP Charging off grid

[Brian S]

Thanks Howard, Yes, That is what I will get from the two golf cart batteries. I will add a battery monitor to keep an eye on the 12 volt system charge. Other than running the furnace on occasion, I would think the biggest draw will be our 12 volt water pump?

I scanned these posts but don't see your unit--what do you own, Brian?

In the 2019 Imagine Owners Manual there's an Approximate Electrical Load Ratings page in the Electrical Systems section. I expect every model will have a similar page with information like this.

Obviously not every listing is applicable to an Imagine, so it may be generic. The awning will draw 10 amps (but is not used much) and the water pump 7 amps, but that is intermittent, too. By far the highest continuous draw will be the furnace (if needed). The power vent has a surprisingly high amp draw, too. If it was left on overnight on a warm evening. 5 amps per hour over 8 hours is 40aH--a healthy chunk of a standard camper's battery capacity.

Currently: ResMed S9 CPAP machine.

Which has this (It's REALLY LONG and requires to know what settings he's running):



I'm sure we can figure this out. :-)

Howard, not sure if you mean the CPAP, or the trailer? Mike got the CPAP above, and the trailer is a 2021 2600RB.
