To my knowledge there is not an output breaker on the Freedom 25. You will need a breaker panel after the inverter's output.
Brian, you're right, there isn't, and that's exactly what I was getting at. The 110 V outlets shown in Brad's diagrams are wrong because here's how the Freedom I/C works:
The Freedom takes the place of 120V shorepower when you are away from shorepower for the 120V loads. So, the shorepower comes into the boat, but instead of going to the AC main breaker, it first goes to the Freedom. The Freedom has an internal switch that determines if shorepower is present. If it is, it passes it through to the AC main breaker. If not, then either the inverter is energized by the Link 2000 or the switch on the Freedom. In no case can both sources of AC power (i.e., shorepower AND inverter power) be ON at the same time.
The AC wiring is: shorepower to boat inlet, to Freedom, to AC main breaker, then to the AC loads, whatever they may be.
Either the inverter OR the shorepower is the source of AC into the AC main breaker.
This may simply be a misunderstanding on how the Freedom works for Brad, or indeed his boat may actually be wired this way, in which case the 120V outlets wouldn't work off the inverter as drawn.
Brad, if I understand you correctly, you said: "When we are off the boat (and typically 100 miles away) is when the other dump load will be needed." I don't get it. Why would you want to heat hot water when you're not there? And if so, and you find that elusive 12V thermostat, what happens if it craps out when you're not there?
I really think you're over-thinking a simple boat management issue.
Why not just let the windmill charge the batteries and turn on and off based on standard wind machine technology? And consider only using a simple DC system I/O switch for the 12V element of your hot water heater. You say you're afraid your mate will forget to turn it off. If you run it from your main DC panel, don't you already turn your 1-2-B switch off when you leave the boat (and have the crew trained to do so all the time)?
I'm just having trouble understanding the basic design criteria for what I consider to be an unnecessary complication to a simple system.
But if you can find a way to make it work, I'm all ears.
