I have a sundanzer freezer model which is running off an amateur
radio power supply. If the power goes out I switch it to batteries.
When I first started the unit it drew power continuously for over
12 hours probably longer so you need to factor that in. It drained
an 80 amp hour battery to 50% and was still not at nominal temp.
Once it is up and running it uses between 4 and 6 amps for
15 to 20 min per hour depending on your settings and the amount
of food stored.
For start up you could probably put a lot of ice inside to get
it to cool down.
There are conversion kits to modify a freezer to a refrig and
vice versa but I really wish I could just flick a switch.
The unit is quite lighweight and when empty is easily manhandled
by one person although lifting is not likely.
I have two 75 watt solar panels which will eventually be hooked up.
