RV 3012 M
Dorn, I dont think it wacky to dump the genset. AC power usage is
personal. The big genset supply the airconditioner operation
efficiently but do a poor job on recharging batteries efficiently.
For Ariconditioner usage, I would bet the effort to recharge
batteries drained from an inverter run airconditioner is more than
running the genset to realtime power the aircon.

You may do well to drop in:
A....two or 4 L-16's house bank
B....The Xantrex inverter
C....a honda 2,000 watt mini genset ( why they call it an inverter??)
D....and a bank of start batteries.
It would be nice to have a small genset that runs on diesel but the
honda can run on propane. if you have not a need to use much heat
when you travel, the bus has storage for that fuel.

I have an over sized battery bank (6 L-16's) which is great for 3
days in the desert followed by 6 hours on the road to recharge. but
when it comes time to charge the large bank while camped, it takes
three times as long as running just two L-16 up to full charge.
There fore, there is not much benifit to a large bank unless you use
the Cat/Detroit chargers to rebank the juice as you drive to another
stop.

I like to schedule battery bank recharge for periods where I have a
high demand of AC usage like heating water and microwave cooking.
when the genset spinns I want to maximize benifit from the fuel it
consumes. I want the two inverter/chargers to have a backup inverter
and major amp recharge when I run the genset. The problem with
the 'Big BlueBird genset recharge exersize' is ;as the house battery
bank gets closer to full, the draw on the chargers goes way down but
the genset spinns effort that is lost fuel$$$$$. If I can justify
other uses for a Honda 2,000 watter, I would like to get one to run
on propane as my onboard propane supply is large and under utilized
(heater is coverted to diesel Wabasto). I would then not need to
cary gasoline.

Several other question about having two independent inverters
supplying power:

Would the two 110 AC outputs would be equivalent to two legs of
houshold current? combined to make 240?

DO the controllers shake hands??
