[RE-wrenches] PV to 208v 3-phase with high leg

[Darryl Thayer]

the usual 208 3 phase is Y and not have high leg.  sometimes you will measure up 
to 208 on the high leg of at Delta high leg to neutral.  If it is Delta 3 phase 
120-240 and a 200 about volt high leg, connect across the 240 volt legs, I e 
that is across each phase they should be 240 each leg to leg connect the neutral 
only if you have one in that phase.  both Fronius and SMA have nice drawings in 
their installation guidelines or at their training courses.

What is the best approach to interconnecting with a  208 volt 3-phase 
service having a high leg? Small to medium  sized PV systems.
