Bit of a drive, but these guys do great work. In Reno. As well as being a Victron and Battleborn dealer among many other things. They will even do a free consult.

Its probably worth talking to a few shops, to see which ones have good reviews as well as who you get a good feeling, and after sales support.
Personally, I am not a fan of redarc. As their systems have some limitations, as far as charging amps/programing, and lack of redundancy. But it may be a use case thing.
