[RE-wrenches] GEC for Micro-Inverters and ACPV Modules

[Mark Frye]

Does anyone have the latest on the GEC for micro-inverters/ACPV issue?

I know it is still in NEC 2008 and I believe 2011 with plans to address 
it in 2014.

I am specifically interested in the issue of GEC means continues 
(irreversible splices) and the whole business of the DC side of these 
devices constituting a separately derived system.

Enphase technical support is fine if the micro inverter chasis is bonded 
to a EGC only, but they leave the lug on the chasis if you want/need to 
build a GEC.

SolarBridge (pre-assembled micro-inverter) seems to be devoid of a 
chasis lug and therefore by extension does not/can not had a GEC in the 
system.

Exeltech (integrated micro-inverter aka. ACPV) does not seem to have a 
lug on its chasis.

Has the industry pretty much moved to not requiring a GEC for these 
devices and if so, how are the AHJ taking it?

Thanks,
