[RE-wrenches] Tiny load problem

[Phil Undercuffler]

If the normal connected loads are within the capacity of a single inverter
(which may actually be possible -- I run my whole house off one Outback
FX2024, microwave, dishwasher, washing machine and all) then you can just
leave one of the inverters in sleep mode or disable output but leave
input/charging enabled.

Which inverters are you planning on using for the generator charging?
Depending upon which brand or how sophisticated you want to be, there are a
couple ways to skin this cat.  Easiest and cheapest is to simply not connect
up any AC output wiring or stacking cables to the second inverter, and
program it to stay asleep and charge only when it sees AC input power.

I used to be religious about making sure my inverter was asleep, and even
had a second baby inverter to power a handful of full time or sensitive
loads.  However, it got difficult trying to explain why you couldn't just
plug the vacuum cleaner into just-any-old-outlet, and as my electronic
widget count expanded it became less and less advantageous to have that baby
inverter.
