Question Chargeverter question

The input for Chargeverter only allows for VAC.

Like I said, I realize that is what the spec reads.  However, someone would have to talk to the engineers to find the real answer. As an electrical engineer, I suspect that the first thing that the module does is convert the AC into DC and then use a Pulse Width Modulation scheme to regulate  the charging voltage and current.  I was hoping one of you support guys would actually talk to the engineers.  If my suspicion is correct, then this would be a very useful device to charge batteries from a wind or water source!

I thought most wind turbines produce AC

@ron From my understand is that most do but then use a rectifier immediately at the source to provide DC.  There are some that use DC generators.

That has been my experience with Hydro anyway and very limited with wind.

I think fuel cells produce DC power, I just can't think of a reason to need to power the CV with DC. 

@ron I am guessing here but maybe trying to use it as a relatively inexpensive charge controller?

I know Hydro is pretty straight forward since "in general" the power supply is constant from the source.

Wind however becomes a very different beast to use efficiently.  Since the power is fluctuating almost constantly to get maximum return takes some very specific wind curves.

On the other hand, most Hydro and Wind systems typically have some kind of charge controller that comes with them.  The challenge would be to finding one that supports Lithium in a meaningful way.

Then I could possibly see how a DC to DC "Chargeverter"ish would be handy. 

Say you have a Hydro system that at the end is putting out 14.4 DC constantly, but you want to charge an Indoor Wallmount battery.  The "Chargeverter"ish could take that 12VDC and not only convert it but would also provide closed loop comms with the battery so as to not over charge.

Just the rambling of an old fart but I think I can see a use scenario.  🙂

It sounds like you just need a DC-DC converter rather than an AC charger. Victron makes numerous models...

So here are the details... for those of you who want to know.  I have an existing solar system, which includes a chargeverter in case I ever need to charge from generator. However I have yet to use it... so it just sits there.  I have lots of wind at times, especially when I have little solar.  I had a sideloader washing machine that broke... that has a "built-in" 3 phase motor. The motor consists of a stator with many poles and wired in a  3 phase delta configuration. The rotor has many permanent magnets on it.  I tried to use it as a generator and it is perfect for that. So the question is, how do I wire it in a useful way into my system so it can charge my batteries??  The obvious answer is the chargeverter that is doing nothing at the moment.  It could provide a safe and controlled way to charge LIPO4 batteries.

The reason for the original question "can the CV take DC?" was because in order for me to properly utilize the power, I have to take what is a 3 phase Delta generator and feed it into the CV!  So if I add a bridge rectifier to the "generator" to rectify 3 phase delta, the CV should be able to make use of it.  All this assumes the following... Since the CV can take such a wide range of voltage and even frequency, I assume that the CV really does not care (as long as I don't exceed 264 volts).  This assumption is of course based upon the idea that they must convert to DC anyway and then use a PWM to regulate the voltage and current.

So since I have never been able to get in touch with Tech Support at eg4electronics!  I am requesting that  the moderator will actually ask the engineers if my assumptions are correct.
