The problem with Battle born heated battery is that it was an after
thought. It uses power from the battery to heat itself
Another shout out for the Trimetric folks. They revised the manuals
recently as well, nice job.

Thanks Dan, that has also been my understanding of all listed
equipment. Certain switches etc will say on them "AC only", or give
different DC ratings. Otherwise the voltage listing is AC/DC.

Hi Glenn;
Ahh that's new from NEC 2014. Thanks for pointing that out, and scratch

Eric,
I like your idea of drilling the weepage holes as long as
they are not big enough to allow critters like wasps to make a home
inside the J-box. We will use aluminum tape on unused
the manufacturer's retest to 1000v. I can't imagine those
blocks not being able to handle 1000v, but.

Its great to get definitive clarification on this MC4/THHN

You can charge with DC directly from a PV solar array without an

ting surge.
Or you could go 21st century, with 48v, Li+ PWM controller, etc
Another option to consider is using existing Li+ battery packs, like
Ryobi's 40 v lawn mower packs.
