YOW, please don't shout. What kind of power controller is he using? Most of them handle this automatically. Gee, there are a number of other things necessary to the design... hope he knows them.

Any inverter that meets UL1741 utility-interactive guidelines will meet all the requirements. My favorites are Outback inverters, but the new Xantrex inverters are nice.

The new Magnum 120/240 inverters are pretty nifty too........they also auto disconnect. If the contractor installing the solar doesn't have a grip on this, I would worry.
