You're welcome, glad you like them
On the max load, if you know to keep it under 130A you're fine. You might want to consider as your battery bank drains, and you get close to your low voltage cutoff on your inverter, usually around 10.5v you'll be pulling more current to keep up with the power demand. So basically that 130A could rise quickly at the low end of the battery state of charge. You might drain the system to see what the current looks like when the bank is about to be depleted.
As for the fuse question, just as
@HRTKD mention the fuse is to protect the wire from bursting into flames if it's overloaded. The way you have it there is a potential problem. Your MPPT could be providing 35A to that bus bar, and then the battery could be providing 150A
You now potentially have 185A going over the wire that is not fused to your inverter.
So yes, you absolutely should put a 150A fuse on the wire going to the inverter.
Also a note about your wire, are you sure it can handle 150A? Looks like 2awg, but the reality is not all wire is created equal. Some 2awg cant handle 150A, while other 2awg can handle more than 150A per the manufacture. So please make sure you know what the manufacture specs for the wire, if you don't know, then you might want to buy some wire that provides these specs (and you trust the company
).
