Depending on the load of the refrigerator/freezer the following list should be able to maintain a combined refrigerator/freezer (especially if you are using a high efficiency type).

1000 W Pure sine wave inverter

80 Amp/hr 12V SLA deep cycle battery x2

30A MPPT Charge regulator

100W Mono Crystaline Solar PV panel (2 might be needed depending on geographical latitude)

With cabling etc - total cost would be around $1000 - $1300.

The SLA batteries could also be charged from a small Generator if no sunshine was available and with 160 A/hrs @ 12V (960 Whrs @ 50% duty cycle) should give around 1 to 2 days use for a medium sized A or A+ rated conventional fridge freezer (i.e rated at around 200 KWhr/year)

The solar power backup solution is expensive, that is until you run out of fuel for the Gennie.

i wasn't specifically suggesting that wattage, all depends on need/usage/size of battery, etc.

i threw my original trailer system (panel and battery only) together on the cheap just for use with the 12V trailer lights, but as guests asked to use it with their 120V toys (like radios, laptop computers, iPad speakers, etc) i then picked up a $20 inverter. the rest is history.

i bought my 35 watt solar panel used for $50 but a quick google popped up new panels like this one for $107:

Easy. I'm not you. You live your lifestyle, I live mine. I'm OK with that.

I'll add...

My home is also the Emergency Operations Center for the tiny township, which does not have a generator. Additionally, my water well requires electric, my septic pump requires electric and my furnace requires electric. Since I raise my own chickens and take a deer or two every year, my freezer has the meat I literally can't buy in the store, and it would be a shame to waste it.

good helpful answers. allows me to understand the needs of others. thnx.

and no offense meant.

Everyone has different answers to why do you do X?

In this case mine goes - need the generator to run the sump pump in the warmer months and the furnace in the colder months. With a kid with various medical challenges I just don't want to add to the "fun" just because mother nature and the local power company have decided that electricity is optional.

Running fridge & freezer is a nice bonus and may have become the driver since my son is on a very restricted diet and even in good conditions we can't always depend on the local grocery stores to carry what we need.

like much in life - you mileage may vary.
