I am still looking for a 12 volt, 2000 watt 110/120v AC inverter, that can
run 24/7 and has a low draw when idle. I would like to be able to stack more
of the same units for more amperage but that is not written in stone.
The problem I am having finding one is that most inverters I have found
draw a lot of power when idle. (I can possibly use a remote on/off inverter)
my battery bank is in a shed about 30' from my home, That is where the
battery bank and solar-controller etc. is located with conduit running from
there to my home.
any ideas?

If you purchase an inverter that has search mode current consumption with no
loads on should be very low. My 2500 watt draws .065 amp while in search
mode.

In general Jacks answer is correct - but beware! Things do not always
work out as anticipated.
A friend with a renewable energy system (solar & hydro) bought such a
3kw inverter (sinewave with "search mode") and the latest low energy
Gram fridge. However, the fridge turns out to have a relay of some
sort in it so that every time the "search" pulse arrives (about every
1 or 2 seconds), the relay clicks. Apart from the disturbing noise, it
was in danger of wearing out the relay and maybe damaging the
associated electronics. In the end he decided he just had to leave the
inverter running. (He is an electronics tech).
You may need to think about the particular loads you want to run
before you buy. Hopefully you do not have any "phantom" loads (eg
plugpacks etc) on your system.
Qu - How small an idle current are you aiming at?
I have a 12v, 1500watt mod-square inverter which draw 550mA when
running with no load. I can tolerate that amount.
The 1000 watt version of the same machine draws 350ma.
Lots of modern fridges have electronics which run all the time even
when the compressor is not operating. I would love to hear how others
get around this problem with a "search mode" inverter.
Has anyone modified a fridge so that the electronic part can run
directly on dc?
