I agree with the other responders re: Balmar.
I've been using Balmar voltage regulators for ~25+ years with great success. I had 2 fail over that period (on different boats at different times) and both times the company either replaced or offered a substantial discount on their latest version. [The 2nd failed unit was several years out of warranty...]
The only thing I don't like about Balmar regulators is they are a bit fiddly to program, but once you get the hang of it it isn't so bad... [Read the online manual...]
I mark-up a copy of the manual with the parameters I chose for future reference.
I also keep a pre-programmed spare mounted next to the active unit so in the event of failure I just have to switch the wires over to the back-up unit [with the engine
off...] to get up and running [charging] again in short order.
Also, they seem to last longer if you can mount them in a cooler environment
than the engine
room... [This is subjective from personal experience...] That may also provide you better comfort while programming/tweaking/observing the readouts...
