Victron's Multiplus and Quattro are drama free. I buried and conduited/sealed all my cabling and had zero issues.
Added bonus: if you use them with a CCGX and are comfortable with MQQT and/or Python there is literally nothing you can't control, automate or visualise with them. The CCGX itself is arm + linux and mostly open sourced https://www.victronenergy.com/live/open_source:start
The downsides are:
1) price but imho you get what you pay for many times over.
2) veconfigure for the multiplus itself is windows only, but runs fine in Wine on Linux and Mac
