Not sure if it's acceptable to tag my issue on to Kbs's thread, but it's a similar topic so here goes. I have a 2016 Quontum PD31 with a residential fridge. I have not previously boondocked but plan on it next trip out. To test I observed that the inverter display (Xantrex1800) usually shows 13.6 when on shore power. When I disconnect shore power the display immediately drops to 12.8 and within a few minutes drops to 12.5. At this point the refrigerator happened to kick on and the voltage instantly dropped to 12 and then the display went into alarm mode. I also noted a change in the sound of the refrigerator compressor. At this point I plugged back in because I knew that the auto gen start would not activate for two minutes and I was concerned about low voltage damaging the refrigerator. Am I safe to assume that the batteries should hold their voltage at 12v for a couple of minutes under that kind of load? The two 12v batteries are original. Thanks for listening.
