Wrench Masters,
I have a friend who wants to empower his enphase array during down times.
Any difference here with what this list has already discussed on AC
coupling with microinverters?
Thanks!
Jeff

Hey Ray and all,
Yes local contractors are being conacted now to get the scoop.
But the Inspectors do indeed fly to the islands and it's not a foreign
country to them. And yes always better to ask forgiveness rather than
permission but only armed with good information!
So again is there any
Canadian code? Bahamas? You my friend have to make serious contact with
local contractors to get the real scoop.
Seems that if the customer owns the whole island, he gets to decide what
voltage and frequency to operate the island at. Are there actually
building officials or inspectors that are g
If the DC & AC float from the ground, your clients will effectively be
insulated from any current path unless they were to somehow touch both
conductors simultaneously. Many countries do not reference one of their current
carrying conductors to ground. Many people feel this is safer. You would
I think the system would be technically required to have an equipment
grounding conductor to connect to lighting fixtures made of
conductive material. I believe this is true regardless of voltage.
If these do not exist, and no metal boxes are in the system and it is

HI All,
I'm wondering if anyone knows how to decipher the serial numbers on arco
16-2000 modules to find a date of manufacture?

Hi Jay and All,
This island is remote and stand-alone - the client owns the whole island.
Yes the multi-cluster box is available now in the US - up to 60 KWs -
European version goes up to 300 KWs.
400/230 would reduce wire sizes over 208/120 before we go to
transformers and allow bigger micr

everything was listed - what are the other showstoppers?
From what I know (and I risk embarrassing myself here) - the code
doesn't specify voltage or frequency
This topic is so funny, its summer.
If you are on ice and drill holes in the ice what about a
small hole for a short ground rod, IF, you even feel it
necessary. I do not think I would bother. Have there been
electrical inspectors out there that are not
fishing/drinking.

HI Jeff,
I don't see how you could as the equipment isn't UL listed.
Then you'd have the issue of what equipment are people going to be plugging
into it, and none of that would be UL either.
I think its great stuff and would love to see it happen, but I'd also like to
know how, but if anyone c
Esteemed Wrenches,
Is there any possibility at all I can install a 230/400 50 Hz Sunny

the neutral and grounding that's going to prohibitive? Or is there a
way around that? Anybody ever done it and gotten it through an ins

It sounds like you want an AC system for your "home theater" system, so make
sure you get a mobile rated inverter if you plan to have a backup AC source.
That way you will have integral neutral-ground bond switching. The mobile
versions are rarely much more $, if at all. Try Magnum or Outback.
I have the very system you are talking about in my fish house. I don't
ground, I only have DC loads.

There are many RVs out there too, and they don't sink a ground rod every
time they park.
Use a GFCI outlet, and I think you'll be at the same safety level as
other portable systems.
(Is there an ice structure building inspector?)
You could still heat up a copper rod with a torch and then drive i

First .. why are you grounding a portable system? It's not required.
In [29 CFR 1926.404(f)(3)(i)], OSHA states the frame of a portable
generator need not be grounded (connected to earth).
If it's a fuel-powered generator, the NEC 250.34 states the frame may
serve as the ground as long as normal
Per 690.41 you probably wouldn't need to ground it for a system like
this, but I like the idea of dropping a ground rod down into the water.
Then curve the end and find a big worm, of course.

That is an amusing concept, and it sounds like a fun project. Why
not poke a hole in the ice and drop the rod in the water? If the
water is not too deep, send it to the bottom. It certainly will be
below the permanent moisture level!
