[RE-wrenches] ConnectDER

[Dave Click]

I have had two of these on my house (I upgraded my system, so had to get 
a larger model) and I really like them. Great guys at the company and 
great product. Major issue is that most utilities don't have a blanket 
allowance for meter collars like this one, so you may end up spending a 
fair amount of time trying to get a utility's approval without guarantee 
of success. For utilities who think that customer-owned PV is The Devil, 
it could be a tough sell trying to get them to make your job easier. 
This can be a lifesaver on some projects where strict 690.64 compliance 
can be expensive-- encountering a 60A interconnection on a 150A service 
makes this worth fighting for, especially on all-in-ones or older 
equipment that the homeowner isn't ready to replace.
