Residential fridge question

[exlnt1900]

Still learning all about our new 335DS. One question I have gotten mixed answers on - our fridge is only electric. To run it while driving I must switch to inverter which is only dedicated for the refrigerator. The question is will the house batteries be charged while driving or only when plugged into shore power? Have received both answers on this question. Thanks for any insight.

The alternator on your tow vehicle will keep the keep the batteries charged so that the residential refrigerator, running off of the converter, will continue to run without draining the trailer batteries. We've occasionally had a day of towing, a night with the residential refrigerator running just off the batteries, followed by a second day of towing before we plugged back into shore power, and the fridge kept running and kept everything cold.

Your alternator will keep the house bank fully charged when driving and the reefer won't even put a dent in the battery bank while driving. You can run your reefer without any shore power or generator for at least 12 to 16 hours. You can put enough in the bank with your generator in 4 hours or so.

Assume that you are using an average of 8 amps while the inverter is running. This will get you down to 50% SOC after 24 hours or so.
