Xantrex pro 18000

[Carlmatt]

Please Help
2015 Thor 31W, Xantrex 1800 inverter, with 3 - 31 Series Deep Cycle batteries that are 2 years old, I have a Whirlpool 18 Cu. ft. Residential Fridge that uses 6.5 amps. When the battery voltage gets down to 12.5 volts, the fridge labors and does a clunking sound whenever it tries to start. Also the fridge does not get colder than 40 and the freezer drops down to 0 The fridge is the only user as I have disconnected the radio , DVD and the TV. The batteries will not power the fridge for more than 5 hours.

What are you asking for? Alternatives are clear, more battery or more efficient fridge. The 1800 inverter is more than what is needed for the fridge.

Have the batteries been replaced since 2015?

Even 2 year old batteries can be bad.

I will remove them and have them tested again.
