[RE-wrenches] Micro Hydro MPPT

[Jeff Clearwater, Village Power Design]

Hi Carl,

Depends on what kind of microhydro output you are talking.

We have installed two systems now with a HiPower 3-phase inductive 
Alt output voltage clamped and rectified straight into a SMA standard 
SunnyBoy (with blessings from SMA).  As long as you don't go over 600 
VDC the warranty applies and the MPPT locks in nicely.

I don't have experience with going direct DC like from a PM motor 
though - probably would work but maybe others have some experience 
with this?

Best,

Jeff
