/diy/ - Do It Yourself

So it looks like wind charge controllers are dumb as bricks, just a three phase bridge rectifier, a big fuck-off relay which dumps it all into a resistor if the battery voltage gets too high, and a battery sense controller to switch the relay. Doesn't look like it's doing any charge regulation at all.
So the question still stands: Two inputs, one battery.

You're on the money right here, looks like I just need to find the right one.
That said, now that I know what I'm after, it's a lot easier to filter down to the exact unit I want.
>sealed AGM, which is most common because you hook them up and forget about it until they die. Cost is pretty good too.
With a sales pitch like that I'm not surprised most people go for them.
I'm more than familiar with charging lithium, I was just hoping that there's something a little more robust when it comes to deep discharge available now.
Basically I can either buy something which fully discharges overnight, (let's say 1KWh) and is robust enough to handle that, or something with 5x the capacity which only discharges 20% each night, perhaps not as robust but hopefully cheap enough to compensate.
I wouldn't think anything's THAT cheap though, or that it would last long enough to compensate, so just grabbing some AGM's and flogging them 'till they die probably sounds best.
