Given the inefficiencies of the charger
, the batteries, and the inverter, you'd probably be better off running the diesel (engine, not genset?) to heat water, but every situation is different.
If you have, say, an Isotemp water heater (750 watts) rather than a Raritan
(1500W), then you might argue that the beating the battery
bank takes from the Isotemp is less than that of the Raritan
. I'm guessing your water heater doesn't have a heat exchanger
connection for water from the engine cooling
If your planned solar panel array is large enough, there's another option: replace the AC heating
element in your water heater with a 12V DC version. It would be marginally more efficient than using the inverter - no losses with DC-AC conversion. Not that I'm suggesting you go that route
