DC DC Converter not able to start my cooler

Hi all.
I am installing an Orion 12 V DC DC (9A) converter which I though could supply power for my fridge, which is using about 4A under normal operations. However, the compressor of the fridge is unable to start when it is via the converter. I suspect it is because it requires a lot more amps to start, than the supported 9.
Am I correct in my assumption and if so, how do I solve this issue?
Thanks.

Add a small battery to the output for the surge?

The better option would have been a Battery protect to run the small fridge.

the battery is 12V, and the fridge is 12V ? if yes, why do you want to use DC/DC ?

Because the fridge is malfunctioning when my charger is providing 14.7 V, as is the default for my AGM batteries. So I have to adjust the charger down to 13.5 V before the fridge is coorperating. Meaning I will never fully charge my batteries.
