while driving you can use a dc-dc charger
which uses your truck's alternator... no need to run generator
not hard to install just requires adding some better wires from car battery to the trailer
Only good if you actually drive a lot.
-------------------------------------------------------------------
there are plenty of budget friendly generators you can use that are quiet
and won't be too annoying
-----------------------------------------------------------------------
Get a battery bank as big as you can, so generator usage can be minimized
maybe only have to run every second day
there are many good budget friendly lifepo4 batteries available that work well with moderate power usage
If you want to power a air conditioner from battery.... that's a totally different story
you'll pay a lot for that!
---------------------------------------------------------------------------
Most cpaps can be used off your battery 12v
check if your cpap has a 12v battery car adapter/connector..
--if it does you can simply wire it to your house battery circuit
Saves having to use a Inverter .. which saves battery power
again get biggest battery you can ... so you can last the night or longer.
as a guide... I have 200ah of (usable) battery capacity
it powers my 12v fridge and allows me to use the furnace
Plus standard 12v stuff like water pump , slides, jacks they don't consume a lot because you only rarely use them ...
If I wanted to add cpap ... I would simply add another one or two batteries
With lifepo4 you can add batteries easily...
my guess <-------- cause I am not able to see your usage etc
get 2 x 200ah batteries lifepo4 with bluetooth
get a knowledgable person that can install the INSIDE where they stay warm
the cable size, type and lugs to join the batteries together in parallel ..... is important
this will last you all night + some extra
generator then can be used during the day when you like
-------------------------------------------------------------------------
Last word on generator ... it produces 120v to run your converter (battery charger)
to get the least amount of time needed to run generator
make sure your converter connections are optimal for lithium charging
my converter negative to frame and battery negative to frame were not great.
It could only allow about 20 amps (half power)
once I cleaned them up ... no money just time I am now getting 50amps from converter (about 90% )
a guesstimate of your nightly usage could be at 100- 120amps hours
400ah battery will give you about 2-3 days .... time enough to get generator fixed if it breaks etc
run generator to charge battery for about 3 -4 housrs as you make coffee and morning stuff... get batteries close to full again
In the evening run generator again before bed maybe an hour... replace daytime use
20amp charging 150ah = 7 hours
50amp charging 150ah = 3 hours
charging times for totally discharged 400ah battery
20 amp charging on 400ah battery = 20hours generator (if totally flat)
50 amp charging = 8 hours generator
get a bigger converter ... closer to 100amp ... 4 hours
which uses your truck's alternator... no need to run generator
