I am interested in the SolarBridge , it has no chasis lug so it must not
require a GEC, right?
So why does it not require a GEC? Is it because it is not an isolated
inverter? Because it is an isolated inverter that does not have a
grounded current carrying conductor on the DC side? Because it
August:
The WEEB or other Listed grounding means between the inverter case and the
structure are not "contiguous or irreversible spliced" and therefore do not
meet the requirements for a GEC.
If the structure is then grounded via a bolt on lug it also is not irreversible
or contiguous.
If you c
Mark:
The GEC is required if the inverter bonds one of the PV conductors to ground
(as Enphase does).
Enphase support may not have a problem with it but not using a GEC (with all
the GEC requirements) on any system with a grounded array is definitely a Code
violation in NEC 2008 and 2011.
I don
Hi Mark,
There have been some recent threads on this list touching on this topic.
As far as I understand, Enphase microinvertes still require a GEC up to
and including the 2011 NEC. I don't know about the 2014 NEC. Enphase bonds
the positive DC module conductor to ground. Pages 16 and 17 of their
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

Hi Dan,
A while back, I had the dubious honor of opening
one of these up. If yours has the dual stator

interesting alignment

Any one had to mess with Kestrel Wind turbine repair? No help from Kestrel.. other than to tell me if I open it I void the warranty. but the bird is over 5 years old anyway. I suspect a fried rectifier. Thanks dbDan BrownFoxfire Energy Corp.Renewable Energy Systems(802)-483-2564www.Foxfire-Energy.c
