Hello everyone feel just mad at myself cant remember shhhht read this months ago but forgot gess age is setting in you must isolate classics do not parelle the dc input of the classics as one that has let the smoke out of one classic cant say enough about midnites service will not recomend any other controller thanks Rayan will get up date and schematic of system when done will use two rectifiers for two classics from now on please put this in you manual should have known about this as made a diesel 9kw dc military APU unit work with isolation with diodes when starting and worked out good cheers Mike Johnson
At this time you can use 2 Classics on one wind turbine if it is a 3 phase ac turbine. You need to use a separate 3 phase bridge rectifier on each Classic other wise they back feed each other and will blow up one or both controllers. Here is a wiring diagram of a typical install with two Classics http://www.midnitesolar.com/pdfs/Ryans_stacking.pdf
