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?
