Hello Mark (and all),
Exeltech AC Module inverters do not have an external ground
connection because they are certified to UL1741 as grounded
through the utility ground. Also, and because all DC wiring
is internal to the inverter, there is no requirement for DC
ground-fault or arc-fault circuitry
Mark:
I don't know the SolarBridge product as well as some others.
Like you, I would ASS U ME the lack of a grounding lug would indicate that a
GEC is not needed.
Referring to the manufactures written instructions on grounding in the manual
is always the best reference.
You are correct, there a
If memory serves, it's been 2-3 years since our SMA friends starting teasing
us with their new micro inverter. Yet as far as I know, they're still not
shipping these buggers..unless someone knows differently.
Does anyone out there know what's going on with the SMA micros at this
point? I can'
Hi John,
I definitely see your point and that is why I was somewhat questioning the
use of WEEBs with Enphase below. Enphases's instructions (link posted in
thread below) seem to indicate a support of running the continuous GEC on
the rack and then bonding the microinverter to the rack with WEEBs.
August:
Yes, the entire GEC requirement is a pain in the neck and IMHO makes no sense
for grid tied PV.
Historically it comes out of the rural electrification days when you had DC
systems actually "supplying premises wiring", i.e. lighting circuits, outlets,
etc.
In that context the bond betwee

Has anyone had Sanyo BA3 module defects? (see attached picture)
I have been trying to contact Sanyo support at 408-861-8404 but it is always
busy. Anyone have other contact name or phone?
Thank you,

Hi August,
I maintain that the WEEB is an irreversible splice.
If you want to disconnect a WEEB from a structure, you must irreversibly
damage the device. It cannot be reused.
Admittedly the force required to remove a WEEB is less than that
required for a thermal splice, but it doesn't take m
No problems here, Larry. In fact I'm still looking for one of those modules
to expand a small off-grid system.

I'm a bit confused by this thread and am looking for some clarity. To that

Yes we have had the exact problem. Sanyo/Pnansonic has refused to replace the
module which clearly has a problem.
Sanyo/Panasonic is not an honorable company.

I did. They were less than helpful. At least the two or three different techs I
talked to. They sounded as green as me.

Hi Dan
Would like to know what they suggested besides changing it to a VFX?

one of my biggest gripes about the outback fx series is only one ac input...
this was a major step backwards from its trace sw series predecessor.
if someone is going to want battery back up on a grid tied system, they surely
are going to want the ability to back that up with a generator. the ra
Eric,
Good questions, and you hit on a number of topics so let me see if I can
address them one at a time, not necessarily in chronological order.
Yes, the optimal application for the GTFX / GVFX inverter series is grid
tie with battery backup. If you just want backup to the grid, the
