Classic 250 & micro hydro

[LarSolar]

Greetings all,

Sorry if this isn't posted correctly - just joined the forum and am learning as I go

I am planning on purchasing a Midnite Solar Classic 250 for my PV array that I'm building but also want to know about the use of a micro hydro generator which uses a full wave rectifier to convert the 3 phase AC that the gen produces to DC.

I know this will produce a 'full wave' DC output - can the Classic handle this "noisy" DC or do I need to invest/build a DC filter before it goes to the Classic?

BTW there will be no need of a 'dump load' to prevent overspinning when the batteries are charged - the gen head is actually going to be run by a smaller gasoline engine - wanted to do this rather than to run the bigger AC generator to charge / maintain the batteries. (I chose an adequately sized engine to the wattage of the gen with a little extra 'room').

Thanks for any insight!

3-phase hydro into your 3-phase rectifier into the Classic should be fine.

The Classic has input capacitors and 3 phase makes it almost no ripple in the first place !

Should be good go go.

Not quite sure what you mean though be the generator helping to keep from overspinning.

It's early today yet and not enough coffee yet so will re-read that in a bit.

... What I meant about "overspinning" is when the load on the hydro gen tapers off as the batteries reach a fully charged state - in a micro hydro application, there's no speed governor of sorts to compensate for a no-load aside from a dummy load - similar, I'd imagine, to a wind turbine setting ... but since I'm using a small gas engine to spin the gen, it's already speed governed ...
