Which came first, the chicken or the egg? In my case, the charge controller or DC shut off switch
ok, so posting in the beginner's forum still doesn't make it easy to ask a question I figure everyone but me already knows, but this is where I've gotten to, and I need a little information on how and why it's suppose to go this way. For some reason, I've assumed the array needed to go through the charge controller before it hits the DC shut off, but I'm seeing now that it's not that way? Could somebody explain to me in layman's language about why, if there are shut off breakers in the combiner box and another breaker for the array at the DC circuit breaker box, it needs to go through another step before the mppt cc (MS Classic 150)?
To be honest here, I have not re-read the manual, which is for a NOS Trace Xantrex dual SW5548, and the power panel that it will be mounted on. I know, I know. I'd just like to hear it from someone who may have, at one time, been ignorant, too. Thanks, Lee
