[RE-wrenches] High Voltage Breakers for Conext Mppt-80-600

Wed Jan 26 14:14:57 EST 2022

It is 600vdc ! Do you want that in a PDP with your 48Vdc and 120/240vac?
I do not believe it to be UL listed for 600vdc in there, and so you are
breaking some pretty big rules here. I do not post much anymore here. Keep
600vdc out of the PDP and for Offgrid we always want high reliability. Just
good design practice!

This seems like a rather
stunning oversight--offering a charge controller without any means to
integrate it into the BOS built by the same manufacturer. 

Just now I laid
a 600 VDC rated touch-safe fuse holder over a QOU breaker. The fuse holder
is smaller than the breaker so it would fit in the PDP. The fuse holder
would be a bit recessed which may look awkward and impede the opening of
the fuse holder. I do know you can buy DIN rail of varying height. Maybe
you could drill out the rivets on the DIN rail and replace a short section
of it with high profile DIN Rail and make a somewhat elegant solution???

Good luck.

Thanks guys,  

Just wanted to make sure I wasn't missing
something. Curious that Schneider doesn't have higher voltage input
breakers.

I use the SQD
fused disco I mount this next to the CC and use the Flex cobra wire for the
low DC voltage and the do have breakers for the context for that

Hi Mike   

No breakers I
know of that fit the Conext boxes but you could use a MidNite Big Baby and
a MidNite 600 volt breaker in it or even a touch safe 1000 volt fuse and
holder they're DIN rail

Supply chain crunches brought on by the pandemic and Omicron's toll on
the workforce are causing shortages of goods. Most analysts agree that
rising prices -- not just in the US, but also across the world -- are
largely consequences of the Covid-19 crisis rather than policy errors by
governments or central banks.   

Infectious waves have closed factories in
Asian manufacturing hubs and caused chaos in transporting products to US
markets, creating a spike in demand. Also Americans have cash to burn after
two years of canceled vacations, closed restaurants and working from home,
a major factor supercharging the price surge.

Wrenches,    

Can anyone direct me to PV input breakers that are rated
up to 600VDC that would work in a Conext Distribution Panel? From what I
can tell, Schneider only offers breakers up to 160VDC.     

Thanks,
