Can I safely run my 12v fridge from my MPPT 75/15 load output

I would like some clarification on if it is okay to run my small 25L 12v compressor fridge from the Victron load output or should I run it directly from the battery. I am very keen to protect my battery so was hoping to utilize the load output disconnect feature to give me some protection, but if I cant run my most demanding power appliance from the load output then I have no protection.

I have a 195w panel, 120 AH AGM battery and all other power usage is USB, stereo or LEDs. Max power for the fridge is 45W.

Thanks!

I would suggest to connect a suitable relay which connects the fridge to the battery when voltage is present on the load output from the MPPT.

Thanks, I understand what you are saying. Would this kind of relay suit - I realise it does not have the correct specs ? I am thinking of a "normally off" relay but am wondering if these relays can sustain being powered on for long periods of time.
