Vaccine fridge & rechargeable lamp

I was having a look at some of the services that can be attached to the NSN system.

The power requirement of the vaccine refrigerators I found are on the higher side of the max power available from the solar generator.

The rating of one of the small-size portable fridges is 12/24V DC - 3.1A 110V AC. Here is the link:

We were thinking of rechargeable lamps also. Such appliances consume very little power and seem to be well-suited for our system. A typical rechargeable lantern with U-tube lamp that operates with just 7W is shown below -
