Just Installed a 18Cu FT Frigidaire in a 2008 AB and I have a xantrex 3000 inverter system from the factory It runs great on the inverter system and my question to anyone whom has experience is when the batterys run low and the inverter power drops below acceptable voltages needed to run the fridge what happens? does the inverter shut off or exactly what protects the fridge from compressor damage from low voltage?This question only relates to a ""what If"" situation as I plan to make sure this situation does not occur

It's my understanding the AC output never drops with battery voltage.. it just quits.

I also have that inverter. There is a low voltage setting that shuts off the inverter when the battery voltage reaches or drops below that setting. The setting is also user adjustable if you have the advanced monitor panel.

Some are set to around 10.5. I suppose if I had the tool I'd probably put that up to 11.5.

Mine is set to alarm at 11.5 and shut down at 11.0. I should note that I have the ProSine from Zantrex if that makes a difference.
