Xantrex 250 DC disconnect question- will the 250 amp work with MS Classic controller?
Getting ready to finally install my system components, and I just read something I need to get straight before continuing. As I was looking up the disconnect breaker, I read that the 250 amp breaker is sized to fit the Xantrex C40 PWM charge controllers. Although I have those cc's, I'm going to use Classic 150 MPPT's instead with my 48v system. Up to this point, I've been under the impression that all is well with what I have. My question is, will my MS Classics function properly with this/these 250A breakers, or do I need to switch to another size for the Classics?
What I have came from a single inverter system, so I was going to get a second (probably get two new ones and keep the old one as a back up) 250A disconnect switch, along with the CD60DC breaker for the array shut off in the same box, which i'll need two also, since this box was set up for a single array into a single inverter. Will the 250A battery disconnect breaker and the CD60DC's work? I have 8kw of panels split into two arrays feeding two Classic 150's, feeding into two Xantrex SW5548's. Thanks for any and all replies. Lee
