Starboard side, near the hull, mounted to a bulkhead under the nav station seat. That area doesn't get the best ventilation, but I haven't used the unit all that much. Some basic weekend charging from shore power and very occasional use of the inverter to power a laptop or recharging a hand-held. That's it, and the inverter would typically kick off after a few minutes of running anyway, regardless of load.

The error I kept getting was relaywelddetect0. I would clear errors and typically after doing that a few times, I'd be back in business, at least for a while. The thing has been nothing but a headache since it was installed. It does charge pretty well, but the inverter is crap and now the whole thing seems to have stopped working.
