T&T: Installing two inverter/chargers on one battery bank

[Mark Richter]

<<I will be purchasing an inverter soon and have wondered about using two
2,000 watt xantrex inverters with two battery banks say 4 golf cart
batteries on each one or a 2500 watt inverter with 6 golf cart batteries.
What I was hoping to accomplish by the two would be the ability to run a
7-9000 BTU A/C to cool the bedrooms off at night off one inverter and
everything else of the other (fridg,tv and lights)but I am not sure this is
feasable ?
Any opinions? What is involved with using two inverters instead of one?>>

I'd favor the single inverter mode.  Most inverter installations I have
dealt with (many) have not enough battery bank to fully utilize the
inverter's available power.  If you separate the loads into two inverter
systems (air cond and other), you will be wasting half your battery capacity
when the air conditioning is not in use.

My old 1000 watt Heart inverter powers my 5200 BTU air conditioner  (which
draws about 600 watts) with power to spare.  One 2000 or 2500 watt inverter
should easily handle a 10 or 12k air conditioner and still start the refrig
and other small loads just fine.  Hook the one inverter to the biggest bank
you can reasonably accommodate, and you'll be happier with the system
performance.
