I understand that DEF (diesel exhaust fluid) used on Mercedes diesels freezes at 12 F. Apparently there is a DC heater on the fluid container and its piping system to prevent that. Is the DEF heater system thermostatically controlled so it doesn't use much energy until it gets cold outside?
We will keep our Winnabago View in an unattended, unheated and no electricity storage lot for the winter in Connecticut. How do I keep the DEF from freezing?
I don't really want to use the built in heater as that will run my chassis battery down. And there may be more parasitic loads than the DEF heater that will run the batteries down. I understand that disconnecting the chassis battery will require all sorts of resetting of things when it is powered up in the spring.
So what do I do. I guess I can use the solar panels to keep both house and chassis batteries charged. Will that do the job? This will be winter light conditions in Connecticut, probably half of the solar input than in summer.
