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
Hullo again,
Can someone comment on the use of SMA Windyboy with microhydro.
I understand that the Windyboy MPPT table is specific to a Wind Turbine.
Does this matter? Is the MPPT table critical in the case of a hydro
with little variation of output ??
Thanks for your help.
