Wrenches,
In reference to SMA TL inverters, 600VDC residential installs,
my supplier has advised me that 600 volt double jacketed PV wire is out
and the way to go is 1000 volt PV wire. Comments? Will I be able to use
my stock of H4 connectors with the 1000V PV wire?
Thanks,
Bill
Seems to me that the best practice for TL inverters is to use
double-insulated conductors from the array string(s) to the combiner (if
used) to the inverter.
That said, there doesn't appear to be any written requirement in the NEC to
use double-jacketed conductors. So as long at the conductor

Yet again this PV wire thing rears its head.
For our PV systems using transformerless (TL) inverters, our standard
practice has been to use double-insulated conductors for all DC circuits
coming into the TL inverter(s), which we believe represents the best
practice.
However, there doesn't
Marco,
For a standard 600 volt non-isolated (transformerless) inverter based
systems, you just need to make sure that your array source circuit
conductors have a photovoltaic or PV wire rating. You can also switch to
standard THWN-2 once you get into conduit.

HI Marco
I think there has been a lot of bad/old information about PV vs double
insulated wire.
However now it only listed as PV wire.

Yeah, 1k/2k wire shows a diameter of 0.26 on the spec sheet, or 0.053093 in^2.

Hi folks,
What is the proper approximate in2 area to use for #10 1kva/2kva pv wire for
calculating conduit fill? I'm on a job site and don't have the specs with me.
Thanks.

I use this site when I need a quick answer. Use RHH (covered) with one
conductor. You get the same answer.

Nice calculator. RHH may be equivalent to 600 volt pv wire, but 1k/2k pv wire
is thicker.

Hello, Mechanix~
I've recently learned there are two flavors of 600v photovoltaic wire. I
thought all PV wire must be normally insulated plus jacketed with an
outer PVC layer but now I see some material marked as photovoltaic wire
but it only has a single layer of XLPE slightly thicker than the
From UL:
Both PV wire and USE-2 wire use thermoset insulation and jacket typically made
of XLPE or EPCV. Nevertheless, other thermoset materials such as CP over EP, CP
over EPCV, SBR/IIR/NR and EP are also available. PV wire may also be
constructed similar to Type UF but using an additional 15
Is double insulated (e.g., Falcon-brand wire) considered PV wire? That
is, the kind of conductor needed for ungrounded (DC) PV systems? Any other
non-double insulated wire type considered PV wire?
And we seem to have a consensus that once the PV wire (for an ungrounded
circuit) reaches a
I'm starting to use the SMA SB transformerless 8-10 kW inverters.
It appears that the new SMA 6-circuit combiner box is being included
whenever I order one of these buggers (at least from my distributor).
Does the double insulated PV wire have to be used all the way back to the
inverter?
