Hey everyone,

I purchased 3x Sp35 Yukons back in Feb and fired them up on Feb 5th.  Living in Michigan, USA, Im paying 15 cents a KWH for electricity.   Doing my due diligence prior to purchasing the units, I came up with a cost per month of around $490.00 total based on 4800 KW.   After fighting with DTE(local electrical company) for several months, I finally got them to come out and due a actual read on my meter and they are saying I owe $4000.00 as of May 28th.  My question is, have did some mathematical error somewhere?  Im sorta second guess myself.

Thanks for any help,
James
