Loaded fridge may require more power

Your math is correct.
Your assumption that a 100 watt solar panel operates at 100 watts connected to a 12 volt system in real life conditions is flawed.

As an example a Renogy 100 watt panel will put out under 5.5 amps at optimum conditions.

Thanks for the continued posts, I had decided to replace only battery right now with lithium but then Thor said it isn’t recommended especially without converter change. Knowing so little about the subject I worried.

But with taking the real life experience from everyone here I will change. Later I will do a full upgrade and add capacity.

Fridge is new 12v and seems to be pretty efficient. I’m confused with remark about using more power if loaded… I thought keeping it full helped keep it colder.
