Kirk,
Could there be a loose wire connection to the breaker? That could cause it
to heat up an trip sooner than it otherwise would.
Cheers,
Dave

Hi Dave,
You did get the Square D part right. See the Schneider website, which shows
that it is 600V DC and does have an off in the middle.

On S
Kirk,
Have you tried IMO (https://www.imoautomation.com/). I haven't seen any
ATS units advertised, but they have a pretty extensive and reasonably
priced listing of DC control equipment.

I think I gave you the wrong schneider P/N back tomorrow. Sorry! You
want an off in the middle and switch the 600vdc to A up or B down I think.

One of the Wrenches reminded me about the Schneider Square D model
below. It is huge and not inexpensive. I thought I had found a smaller one
from Siemens but it only had a 250 vdc rating. Let us know if you find a
smaller version with 600vdc.

This whole high voltage connection discussion got me searching, and I
found Phoenix Contact makes a DIN rail mount terminal block that is 1000
v rated. That would seem to make way more sense than using MC 4
connects in a J box, and would provide the access for voltage readings
and torque check
I have a system where the SE1 inverter fried internally. The 60A AC output
breaker tripped several times, as a result of the homeowner resetting over and
over until he called me.
I replaced the inverter under warranty and all is fine, except on sunny days
the breaker will trip at about 40A,
Hello,
Any recommendations for sourcing a 600 vDC bypass / transfer switch? I know
Morningstar used to make a manual stand-alone, but now it appears to be offered
only as part of their HV charge controller. Thanks.
