AGS with Residential refrigerator
Hello. Can anyone advise me on this AGS issue? I've got a 2016 PD31 Quantum with a residential refrigerator. In two years we have never been in a situation where we relied on the AGS but will be soon. I have just upgraded to 4 new 12V marine batteries and tested the system. Inverter registered 13.3V when I disconeccted from shore power. With only the fridge running, batteries held above 12V (AGS set point) for over 20 hours. At 12.2V the fridge made a different sound (maybe the defrost cycle?) and voltage dropped to 11.5. If it stayed there for 2 minutes the AGS should activate, but after about 30 seconds the fridge made a click sound (defrost turning off due to low voltage?) and the voltage jumped back up to 12.2. The process repeated a few times until I became concerned about low voltage potentially harming the refrigerator and plugged back in to shore power. Any thoughts? I plan on being absent from the RV for about 36 hours and would like to feel confident the the refrigerator will remain cold. Thanks!
