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..... Me |

Me 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; |

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? Allen |

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. Too funny....(c; |

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