Heart Interface Freedom 10

[freeheelbillie]

Trying to workout proper use while on shore power and underway (engine off) with a Heart Interface Freedom 10 inverter / battery charger.
Current set up is position 1 on battery selector is for the 2 house batteries
Position 2 is the engine start battery
Note: I have a refrigerator that plugs into a cabin plug that runs on shore power with batteries switched to off and 120 shore power on regardless if cabin plugs are turned on. Ice box has been converted to refrigeration but only runs on DC, with or without shore power on and refrigerator must be switched ON, on DC panel.

Currently for shore power while not on the boat I leave the AC off, plugged in and batteries off with inverter/charger on. Refrigerator runs, ice box does not.
While on shore power and using the boat, AC switched to ON, DC to position one and what should I do with the inverter? What about under way and engines off?
Hope I am explaining this clearly enough. Thanks!

Sorry, I am not gettting it very clear myself. Also I am not sure what your question is?
You dont like the way it works now? was this changed by you? or was this the way you bought it?
HEART is the old Xantrex - you wont get support for it, but you might find manuals.
From what I understand the only thing you mention that you MIGHT run when on DC only is the refrig right?

I finally got it figured out. I have a remote panel which allows me to shut down the inverter and only run the charger. Long story but all good now. The previous owner has the electrical system set up odd but solid, just took sometime to work out AC, DC, shore power and battery configuration.

I gather you have two refrigerators, one a 120V unit and the other a 12V conversion for the ice box. It is somewhat redundant but if you are talking about the 120V being an inexpensive dorm unit it may make some sense. Not very clear about your question but allow me to make a comment; it seems to me the setup intends for the 120V unit to be used at the dock and the ice cooler conversion to be used at anchor and underway. One boat refrigeration maxim is, do not get underway before your mobile 12V refrigerator has had time to reach working temperature as they will use 4-5 times the power just to cool as they would use to maintain temperature. This means you would need to run both refrigerators at the dock at least in preparation to go out. If the battery charger is on while the 12V refrigerator is running life is good as the batteries are not giving up any charge. Many people with a single refrigerator run their 12V refrigerators 24/7. I would not use the inverter for refrigeration at all, not at the dock and not underway. I would keep the battery charger on at all times, obviously it would not be working when not connected to shore power. Using a cheap 120V dorm refrigerator might save hours of use in your more expensive 12V compressor while at the dock but your main refrigerator when underway will be the 12V unit running off the batteries capacity. Don't know if this answers your question but hope it helps. Do your homework as there are some tricks to using refrigeration more efficiently in boats. Just seen you have your answer but hope this info is at least helpful.

Sound advise, thanks Benny!
