New System Design Help Needed

[Beyla]

Hi and thanks for looking into my request for help.

I have a Classic 150, Magna MS4024, MNPV6 Combiner, and an 8 X 6volt battery bank configured for 24 volt. My MNPV6 Combiner is on the outside wall at eye level and approximately 4 feet from the solar array. I plan to have 6 strings of 2 panels going to @15Amp breakers in the MNPV6 combiner. I could also got with 4 strings of 3 panels and us 4X15@mps and a 63 amp breaker for output to disconnect.  I require an ESSA inspection approval and that means a disconnect on the outside wall for the solar DC incoming from the roof, they won’t accept disconnecting by swinging open the MNPV6 cover and shutting the 6 breakers off t disconnect the solar array. I could position a Disconnect with a red pull down level on its side below the combiner and then feed the positive and negative from the output of the combiner to the disconnect and then to the inside. I think I will require the e-panel 250Amp to facilitate and comply with the installation. I would appreciate any help you can provide me with putting together this design and have it comply with the solar safety code. I have all the wires and proper metallic electrical conduits. My distances are short since the panels are directly above and farthest solar panel to combiner PVC cable is at most 18 feet away and closest is 4 feet. Thank you to anyone who provides input.

I'd put the DC disco after the combiner.    Will they let you use a breaker, or do they want a box with a handle outside?

Here is a link to their requirement, it’s a little obscure and some companies have said I need the red handle but my combiner is so close to the array and on he wall with 6 breakers that can cut the power.

The MNPV6 Breaker combiner box has a version with a red handle on it to turn off all 6 breakers from the front, did you know?

No, they won’t accept that because it’s a two step process, I know, kinda ridiculous, but they have their ridiculous reasons, so I can’t use that kit. I would still prefer to get the certified disco-combiner with birdhouse, not an issue for that, thanks for your input, much appreciated.

Beyla, what province are you in?  I don't like the sounds of this ' don't like the 2 step process' stipulation...

Ontario.
Thanks.

I got the DiscoCombiner 4X with 6 circuits and the red arm along with the PSB that connects it to the birdhouse, along with the epanel but not the -RSS panel, so I had to buy a Remote Trip Breaker @250 Amps and a Battery Disco board. I posted a new thread for help on how to wire these two components into my STMN250 epanel.
