Take it from someone in the trenches out here in the Aloha Stateyes, we
have to jump through these hoops. The utilities here-HECO, MECO, HELCO and

documentation. It's been my experience that HECO and MECO are more lax

HI Howie,
I've seen someone use a single 4/0 fine stranded cable with a regular lug on
the end of it.
they then cut the top of the hole out to make in a sense a U shape.
Each side of the U fit into each side of the 2 hole barrel connector on the SI.
Super slick iI thought.

Yes, Hawaii requires custom settings and they require the installer to certify
the inverter has been programmed to those settings.
We have a menu choice for Hawaii in our setup menus.
If you have older product we can update them remotely once connected to the
internet.

That's correct, it's a 57.0 - 60.5 Hz operating window.

According to that website, the requirement only applied to systems

So if the lug is the plate type with a screw through the middle, then
wires can be inserted on both sides of the screw (using the correct wire
size of course). I'm assuming this would apply to other brands (GE ,
Siemens) with that type of plate connector as well. Any other breakers

I slept at a Holiday Inn Express last night. :)
But seriously, I'd put myself up against most NABCEP certified solar
installers when it comes to technical knowledge, design, safety,
troubleshooting, etc. I generally wouldn't put myself up against those
non-NABCEP folks with vastly more experience
We had the same request in NC by Duke Energy. The inverter mfg. says they can
do it but it'd be outside of the values on the label that the inverter is
listed to. I don't think Duke cares, but the AHJ may.

Ian - While some jurisdictions do choose to require NABCEP certification to
qualify for incentives, NABCEP certification does not replace local
licensing. Please see the disclaimer at the bottom of the NABCEP About Us

Table from the Square D catalog for QO breakers shows a very limited number
of breakers/wire sizes that can be double lugged.

Folks,
I was told that because the HI grid has poor frequency control, grid-tied
inverters have to have their low frequency limit set to 57 Hz so they can
ride out the worst low frequency events.
I find it hard to believe that this has been done for every single inverter
installed in HI.
Greetings wrenches;
I just watched a video from Midnite Solar, where they avoided double
lugging a breaker by using uninsulated ILSCO taps. I've used these taps
before as well, but never felt it was an optimum solution, as it leaves
quite a bit of uninsulated metal in close contact with the a

Not sure what is in the manual now but...
The lugs in the SI 5048U are dual 2/0.
We had to use parallel AWG #1 because we kind of painted ourselves into a
corner.
The breaker in the SI ended up being 250 Amps, the conduit fitting was only
1.5" and the wire bending space was too small for
Hi Ryan,
Does that mean that they have changed the internal SI lugs to handle 2/0,
so they now they only require 1 conductor on the positive and negative
sides? Or are the 2/0 lugs in the epanel?

I understand it to be 2/0 now that MidNite has the Epanel released (Or
starting to release) for the SI.

I am unsure what others refer to, I have used the attached spreadsheet in
