[RE-wrenches] More Bypass Musings

[Dave Tedeyan]

Hi All,

Now that some inverters have "smart" load capabilities, I am musing on
whether to put in a separate bypass for each smart load. I am thinking
specifically about the Midnite AIO inverter, where the Smart loads are
powered directly from the inverter, rather than just providing a relay to
cut power (like in the Avalon SEP, if anyone has used those). The Midnite
AIO also has provisions to run other backed up loads directly from the
inverter as well.

But if there was a system failure, and you have a bypass switch installed,
this will only power the loads in the backed up loads panel from the grid,
but not the specific loads that originate from the inverter. Are people
installing bypasses for every individual load that originates in the
inverter? I was just looking at William's interlock system, but I don't
think that you can utilize that kind of system to have some smart loads in
there as well. It seems like you can utilize the panel he labels "inverter
feed" on his one line diagram to power other backed up loads, but the would
not work for a smart load.

Cheers,
Dave
