Re: Xantrax Link 2000 Battery Monitor
I want to buy a Xantrax LINK 2000 - if anyone knows of one for sale- please let me know! Please email me at firstname.lastname@example.org
thanks very much,
Sydney , Australia.

Due to a relative immunity to weight kept low, I'm able to have more battery capacity aboard than most, and this is the key to my evil plans: constant charging in one form or another to keep the whole battery system above 80%.
Note that while I've stated I don't care to run the alternator to charge the batteries, if I have to, I'll have to, and then I'll have to consider a built-in genset, or more solar/wind charging capacity. But we don't anticipate running A/C or electrical pressure/hot water or vast freezers or other big draws offshore. If this changes, I would have to rethink it. Right now, it looks as if even under marginal conditions, I will make more amps than I can use. Put me in high latitudes in winter, and this might change, but we plan on being for the most part between 40 N and 40 S.

Flip a coin... I'm actually planning on getting the Microlog unit and installing it next spring.

Add the sun in the daytime and you've got a lot of juice flowing.
I am fortunate in having bracketed steel plates designed to hold davits securely welded onto my transom. I could quite easily have a "tipping" pole trailing behind my stern, well clear of the windvane and the rudder. A small block and tackle on the arch would bring the thing upright again, and ready for wind service.
It's certainly something to think about, particularly as so many distance cruisers appear to be raving about it:

But this unit has its own attractive features, and manually transferring numbers isn't such a big deal, because once I know the draws of all the usual power-sucking devices, I can complete my energy budget.

It's really important to sit down and work out a power budget, and be scrupulous. There are small systems that are running and are easy to forget about, like a sniffer, a propane shut off solenoid, radio, and so forth. To be realistic you should list everything and to be safe double it, and you'll probably be closer to real consumption. And you likely are aware that these alternative power sources very rarely achieve anything close to their rated output. That's why it's important to have the best charging system you can afford.
And while redundancy is a very good idea, remember that reliability tends to suffer the more complex the system is.

Might want to look at this battery monitor as well. A bit less expensive than the Link 20, and does two banks.

Thanks for this discussion, guys. It's helping me focus on what is a complex way to achieve a simpler life.

Part of my design ideas is extensive switchability as the key to redundancy: I want to have the ability to vary charge sources based on availability, but not necessarily to combine them, which I agree, on a breezy noon hour, might prove a little rich for the system to absorb along with shore power.
