Recommendation for PV to MPPT

[Jack2of3]

HI All,
I need some recommendations for connecting my PV through circuit breakers to my MPPTs.

The VOC with 1.6 factor is ~105.
The amps are ~27.

I will have two separate strings that will not be combined, each going to their own MPPT.

I need an outdoor rated enclosure and the circuit breakers.

I cannot bring myself to spend the 400+ dollars on the midnight solar MNPVxx.

Thanks.

How about outdoor + DIN rail ( https://www.amazon.com/VEVOR-Fiberg...ounted-Quarter-Turn/dp/B091FHCBLG/ref=sr_1_38 ) OR just any outdoor box and add you're own DIN rail. A variety of circuit breakers would snap to the DIN rail..

Maybe Midnite Solar DC breaker 150vdc @ 30a will hand on DIN rail - https://www.amazon.com/MidNite-Sola...te+Solar+dc+breaker+30a&qid=1634152971&sr=8-5

I just added a page to the linked resource discussing the use of breakers as disconnects.

Thanks. Those are the breakers I was considering. Bought two of them and 8" DIN rails plus a Stainless outdoor rated box with Glands.

Appreciate the links.
