Thought I'd reach out to the community and see what others have done in a similar situation....
I want to replace my current controller/battery monitor with Victron equipment, as my MPPT won't handle anything above 35-40V. I have 3 panels on the roof that I want to rewire in a mixed configuration (2 smaller ones in parallel, then in series with the bigger one). The voltage could potentially be 40V or more, hence my need to upgrade my MPPT. Also, I'm not happy with the performance of my current MPPT, but that's another story.
My issue is this - the hole left by my current MPPT is about 5 5/8" x 4 1/8". The Victron 100/20 MPPT, for example, is smaller, so there would be gaps around the edges and no good way to screw the MPPT to the cabinet. Any ideas about cover plates or other ways to fill the gap? I have the same issue with the battery monitor, as I can't use my current one with Victron equipment. The hole is larger than the BMV-712.
I could go with a 100/30 Victron, which has larger dimensions than the hole I have, but it's overkill, as my panels wired in the configuration I want won't generate more than 9A under ideal conditions. Even if wired in parallel they won't provide more than 18A ideally, and I've never seen them produce higher than about 16A, albeit briefly.
