My work here is done. It is looking like I have found an alternative to propane and running the fridge (Dometic RM8551 4.3 cu ft) while driving, or anywhere the sun shines. Here is what I got:
- One each Lithium Battleborn 100ah
- One 190 watt solar panel permanently attached to trailer roof and connected.
- One Victron 100/30 solar controller.
At 11 am this morning in yard it was 70°F in fridge, 85°F in trailer. Full sun outside. I fired up fridge on battery, 4 dots. Battery was at 13.6 V. Also just for fun, turned on inverter.
At 2 PM sun on street side and the trailer was at 91°F inside. Fridge showed 54°F. And the Battleborn showed 13.5 volts. That would be 14 degrees cooler in three hours.
Quoting Sparky Anderson, you coulda knocked me over with a feather.
