Please clarify the above, as wiring both the input and output of an
inverter to a distribution panel IS really a bad idea, and doesn't
conform to ABS or NEC codes........

============================================

The distribution panel (or behind it) is usually the only place where
you can find a centralized point where you can interrupt the power.

The inverter has to be wired in such a way that it can never see an
independant source of AC power at its output terminals. As long as
both the AC input to the inverter/charger and the inverter output pass
through seperate circuit breakers, there should be no issue with
wiring codes.

How would you do it?

Bzzzzt, Wrong answer..... would you like to try again, for what is
behind Curtain No. 2 ?

Never EVER have a Input Feed and an Output Feed in the same Panel
and on the same buss. That has got to be the dumbest Idea I have ever
seen, posted to a newsgroup, and "Totaly" against ABS and NEC Electrical
Codes. Yes, it is possible to so such a thing, but to keep people from
doing so, is why there are ABS and NEC codes in the first place.

The correct way to do this is to have an Input Distribution Panel,
and an Inverted Output Distribution Panel, and any interconnection
directly between the two, would need to be thru an InterLocked Transfer
Switch.

Shore Power, Generator, would be interlocked so they are mutually
exclusive inputs to the Input Distribution Panel. That panel then
feeds all noninverted loads thru individual breakers, and the Inverter
input, thru its own individual Breaker. The Output Distribution Panel
would also have it's own individual breaker in the Input Distribution
Panel for Transfer Power Feeds.

Inverter output, Transfer Power Feed, would be interlocked so as to
be mututally exclusive inputs to the Inverted Output Distribution
Panel. All inverted power circuits would then be individually
breakered from this panel.

This keeps the Genset and Shorepower mutally exclusivly seperate
from each other so as no combination of breaker settings could
ever connect them together.

This also keeps the Inverter Input and Output mutually exclusivly
seperate from each other so that no combination of breaker settings
could ever connect them together.

Any other system, that does not provbide the above Mutual Exclusivity
will certainly, and eventually, let out the MAGIC SMOKE, that makes the
electrons run thru the wires. Either you, the mate, or just a friend
aboard, will make a breaker setting mistake, and out will come the
MAGIC SMOKE, and the results will be BAD.....

All ture, except the part about two separate panels. My main AC panel
has interlocks for shore/genset/inverter plus distribution for 2 30A
circuits.
Off the shelf and ABYC accepted.

Does that panel with the "inverter" position disconnect the
inverter/charger's AC power input when it goes into the inverter
position?....keeping the inverter from powering its own charger??

Too funny....(c;

The thing that bothers me about "automatic" inverters like the smoked
Freedom Marine 25 setting on the floor beside me is the apparent (to me)
high rate of failure due to no apparent cause. Mine smoked
during operation with a low load at anchor after several hours of
trouble free operation that day. Then I started noticing how many
"refurbished" marine inverters were available on E-Bay. By the way mine
was a refurbished unit.
Coincidence?

I had a Freedom Marine 30 on my old boat with a Link 2000 panel. Both
were troublesome and required ongoing service.

Must be the luck of the draw. Our Freedon 25 has operated flawlessly for
over 5 years.

No, but the inverter protects itself if I inadvertantly power up the
inverter without shutting down the charger.

Thanks. It should shut the charger down when the inverter comes on.....

Wonder how many big boat chargers are loading down running inverters across
the planet, tonight....(c;

Neither the charger or the inverter has a provision for such.
