Square D QO Breakers for DC

[Paul_NJ]

I see Square D's QO breaker spec sheet rates them for AC and up to 24v DC. I'm in that voltage range. Readily available, I was thinking about using them for building my panel-to-controller combiner, battery fusing/disconnect, and distribution to loads. Anyone used these breakers, and load panels for DC?

Heve used 10's of thousands of them. What do you want to know? Just about every Tom, Dick, and Harry solar want to be company uses and re brands QO breakers for a huge markup.
