<p class=MsoNormal style='margin-bottom:12.0pt'><font size=3
face="Times New Roman"><span style='font-size:12.0pt'>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. <br>
<br>
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. <br>
<br>
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.<br>
