The plan is to go back to 24, yep. I was seemingly typing with my brain disengaged ;-). Actually I wanted to know the cutout of the 24V FX.
Is there something up over at Outback? Tried to download the FX manual and got blocked.
The reason I want to go back to 24 is that my windmill (that I was working on this evening, actually) spits out 40V/70A, and figure it would be a good match, after line loss, for a 24v system.

Thanks!

Hi,

I downloaded some docs from Outback a couple of days ago with no problems.

The 24V inverters can be set to 20V low battery and possably lower but 20v is as low of a limit as I would go with the Alcads.

Yeah. Turns out it was a Netscape vs. Explorer thing.

I will keep that in mind, thanks!

Yessir, I did that, and I got three 80s instead of just one (got a deal worthy of a pirate ;-).

And for now, I connected each panel to a different string (with it's own fuse and switch) to make sure I got a nice even charging at low amperage. Of course, that means I can't track the input with my TM500 right yet, but it is very nice none the less!
I've actually had the inverter switch itself off from a peak input of over 15.5v on the second day I was charging, and I was hearing some slight bubbling, but not since. I'm guessing they were just getting nicely stirred up?
Now, getting much more than 13.9 v on the total bank is an achievement, but it takes a LOOOONG time to get down to 12v... easily 100AH. I think that there's still room in the batteries for more juice.
And then, when I get a trencher in to bury the cables to the windmill, and get that new inverter... ;-).

Thanks!
