So I already have 2 Lynx distributors and was planning to wire the multiplus 48/5000 into one of the fused connections followed by 2 MPPT into their own fused connection. Then the second lynx was going to have 1 Pylontech US5000 on each fused connection (4 in total).
However I hadnt planned any battery disconnects / isolators on them (or the multiplus), after further reading up on things it seems like Mega fuses might not be appropriate for the batteries and Class-T fuses should be used. So now I have a couple of options
1. Cut the pylontech cables shorter (2m currently) and terminate each of them into a Class-T fuse holder (and then possibly a disconnect switch), then onward to the Lynx Distributor with the mega fuses.
2. Replace one of the distributors with a lynx Class-T power in and create 2 banks of 2 US5000 batteries (again with or without a disconnect somewhere?)
Option 2 now has an issue of joining the Class-T power in to the distributor as the power in would be M10 and the distributor is M8. Putting the power in on the right would work as the hole is bigger than the M8 screw. But would this create a poor connection / resistance? Or not as long as things are tightened accordingly?
I feel like option 1 is the cleaner solution with more protection but maybe I've overlooked something? Adding battery disconnect switches can only be a good thing (as long as everything is tightened to minimize resistance)?
The same logic will be applied to fusing the mutiplus via a Class-T instead unless this is completley uneccesary as the short circuit current is nothing compared to LifePo4 batteries and the mega fuse will be sufficient.
