I already have the Fridge. Previous owner put in a Danby 7 Cubic Ft. It's wired to a switch for AC/DC. I also have an 1000W inverter dedicated to the fridge for that setup.
Okay, I am official CONFUSED !
I am guessing you don't have accurate wiring diagram so I am going to make an ASSUMPTION ! I do not believe that Danby makes a DC compressor refrigerator. It is an AC powered refrigerator with a dedicated inverter. The switch either connects the refrigerator to shore power (AC) or to the inverter and battery (DC). Not sure how that battery gets charged.
How long you want to boondock, WITHOUT running the generator is the key point. The simplest solution is to just replace the current battery with a lithium battery. The size depends on how long you want to run the inverter and refrigerator before firing up the generator.
If you do this, you need to find out how that battery is charged and replace that charging source with a lithium battery charger.
Last and probably MOST IMPORTANT is install a good battery monitor on that lithium battery, like a Victron Energy Battery Monitor. Now you can tell from a quick glance how much longer you have before your battery will no longer run the inverter (i.e. you need to charge the battery)
You are correct, sir! It's AC Fridge w/dedicated inverter. There is no wiring diagram and to be honest being an older motorhome the wiring is quite a mess as its been changed/modified by previous owners through the years. Plus I am no expert, just an average guy when it comes to electrical.
The current battery setup is there is a chassis battery (for cranking) and three coach batteries. 2 of the 3 coach Batt are up front next to the Chassis battery and the other coach battery is located at the fridge, but it's wired to the other 2 coach batteries up front. So, all 3 batteries are charged by converter charger when plugged into shore/generator running. This is at least how I have traced it out.
I called Battleborn and after speaking with them, based on my current setup they recommended me changing all three coach batteries to Lithium, installing a battery monitoring system and using a Lithium battery charger to charge up the batteries when running my generator/plugged in.
