48vdc is the standard for larger off-grid homes and ranches. This is converted to AC rather than used to run lights and appliances. Although some have 48vdc to 12vdc converters to run some house lights, fans, and/or other appliances near the battery box. So most solar/wind companies sell 48vdc equipment (chargers/inverters/etc.) A 48vdc mppt charger will get you more total watts from a solar array.

In most boats with enclosed engine spaces, the equipment and wiring stays pretty dry (think about the engine that you have today). For sailing auxiliary conversions, corrosion has not proven to be a serious problem for the members on this board.
