The UL listing is only good for 12 or 24 volts, the manufacturer listing
carries no weight if the defecation hits the rotary oscillator.
UL is the one that counts.
If you're using an MPPT controller unless the panels are wired as single
panels you can't use the QO breakers. I have always run
Who was the inverter manufacturer? Please respond off list, I just had to
ask.
I would have sent it off list but it came as a bounced message.
Thanks,

The QO breaker I saw fail was a disconnect switch for an Air
303. The run from the battery bank was substantial, and the wire was
number 10. At the time, I calculated the amperage available (I
-V/R) and the short circuit current available was not close to the
5000 amp AIC of the breaker
Does anyone have experience with Synergized Solar? How was your experience?

HI Drake
I don't know if this could apply to your situation, but I've seen the QO/QOU
fail from debris getting into the breaker itself.
Around here there are insects that deposit mud into small openings, like on
those breakers.
I've seen this cause the breakers to fail.

I have had Sanyo refer my company but there is a company in Vermont that
takes leads does not pass it along to their dealers in Maine we all
know about the poor dealer service w/commercial jobs Sunpower.. the
gestapo of solar companys!
I have had Evergreen sell modules to potiental
I've also seen failures/ nuisance tripping due to loose connections at the
breaker. The heat then wreaks havoc on the breaker internals.

Quick poll- how many inspectors/utilities out there require the live on
both sides label for AC Disconnects, even after you explain to them
this only applies to DC disconnects? Even though it's inaccurate, I feel
that it at least gives unqualified personnel pause before they open up a
switch
I only use this signage, when its true.
Gridtie inverters interrupt output in milliseconds, so I don't use it on AC.
My understanding is that it does apply to array disconnects, as the inverter
capacitors could still have a charge, that would render the live on both
sides idea true on DC.

Without any word, they have stopped taking orders.! Not only could they not
fulfill an immediate need, they refused to even take a pretty nice order for
future delivery.
Who is still getting Kyocera? Whats the deal.? Are they dumping the small
accounts?

Don,
AEE has been good to me over the years. They have several flavors of
PVs, though I believe no Kyo.
