[RE-wrenches] Solar accumulation panel

[Bill Brooks]

Andrew,

 

It does not exist. We tried like crazy to get it into the 2011 NEC, but to
no avail. At the last second the proposal was put on hold until the 2014
NEC. Major bummer. For now it can only be done with AHJ approval. Many allow
it but it is not in the NEC. Alternatively you must use the sum of supply
breakers no greater than 120%. Much more restrictive.

 

Bill.

Team wrenches - I feel like I've seen a provision in the Code for installing
a sub-panel to aggregate PV inverter outputs for the purpose of simplifying
the actual grid connection (such as for a line-side tap) but I can't find it
in 690.  I also seem to remember specific verbiage that needs to be on the
panel along the lines of "PV circuits only.  Do not add load breakers." to
ensure compliance with 690.64(B).  Does anyone know where I can find this
info in the NEC?

ever use in just about 8 minutes. And it's wireless!"
