wind controller [RE-wrenches]

[Frank Lewon]

<x-flowed>

Hi All,

Frank Lewon BZ Products here.

We have several customers using the MPPT500 in small wind/micro hydro 
applications with good success reported. We have not specified the 500 for 
this application and have no field data. External rectifier and break are 
required.

BZ Products is not recommending using the 500 in this application.

Frank Lewon BZ
