[RE-wrenches] irrigation and direct solar

[Darryl Thayer]

That is 480 x 1.73 x40 A x.8 or 26 kW in the peak of the day, five or 6 big 
trackers, or about 50 kW of fixed array.  ( I assure they want 40 amp breaker?  


I have run 3 phase speed drives from solar array directly into the DC Bus of the 
speed drive.  But it is best if it has a gen support.  No need to invert just DC 
from array to speed drive and generator is auto loaded.  If the solar can take 
the entire load, the gen does no work.

Wrenches,

I have been contacted by an irrigation company who would like to explore
options of remote irrigation systems.

He tells me they need 480vac 3 phase at 40A.

Is that even possible?  I did not believe it would be.
