Interesting, thanks hotel california.If you do a search on the forum there have been people having the fridge cut off due the heat . This is not a common thing but if you plan to go south in the summer the fridge will need to work hard , special if that side of the Cali is facing the sun.
There are lots of tips&tricks on the forum i did a DIY hack myself (if you search) and as with many California bits some make them DIY others want to pay (a lot ?) for stuff ready to go.
Like many things it comes down to what you want and what you are willing to pay .
I’ll not bother until i experience a problem but if I do, to protect against fridge and charge controller shutting down in extremely hot situations it’s not really much money.Too much money to waste
