Greetings all. I am just wondering if I have correctly connected my 2 PV arrays to a Classic 150 via 2 x breakers. Attached is a diagram of the connections up to the Classic 150. The diagram explains the equipment involved.
The way I do it and most combiner boxes is to have each array positive go to it's own breaker . The two positive breakers feed into a common wire that goes back to the controller that has another breaker sized for that wire. The negative goes direct to controller with no breaker .
So PV one to 15 amp ( or 20 depending on wire size and array) PV two to another 15 amp . The two positive breakers feed into 6 gauge wire ( for maximum power input my classic can handle ) . That six gauge goes to 60 amp breaker that feeds the Classic. The two array negatives are tied together in combiner box with 6 gauge and go directly to Classic negative input .
There is more info and schematic here http://www.midnitesolar.com/pdfs/MNPV_Instructions_Rev_A.pdf

I'll vote for using a std combiner box, not cobbling something together.
