what kind of bins??? If there just for stoarge and no drying single phase will work ok. Even if drying if your not going to go over 400 amps of power it will work... That is what we have and while three phase woould be nice if it were here we get along ok. Wouldn't advise running much over a 20 horsepower at one time on it though. We have mostly ten horse and under on the bins and have a total of slightly less than 100 hp. don't try  to start them all at the same time.  It will suck the lamps from the next door neighbor.

   have a talk with the power company.. see what they think
