I use the Goal Zero Yeti 1400 Lithium together with a 300-watt folding Kyocera Portable Solar Panel Cells.
The system is expensive to start with but well worth the $$ in the end.

We got it to power the small 230lt 12v fridge, 12v TV, 12v pump, radio, 8 x LED lights, and various small items that needs charging (phones, laptop, cordless tools, etc).

Had it for about a year now and it sure does the job  ;)  Also if you charge the Yeti with the optional Solar Charging Optimisation Module (MPPT) then the unit will be charged in about 5 hours with good sunlight  :P

If you have not already got the appliances consider an inverter or two and 240vac appliances
The appliances are much cheaper to buy/replace and source and they are in general more efficient and reliable.

I have gone 24v solar to match my bus now motorhome base voltage. I can jumpstart my starter batteries from my solar battery bank and recharge my solar battery bank from my main motor on the move if needed.

I can recharge my phone etc from standard 240v chargers   sssoooo muvh easier than 12 or 24vdc stuff
The system can even be plugged into the mains when available and charge my batteries with my 240-24v charger.
1kw of panels on the roof, two 3.6kw inverters and two large 260kwh batteries all controlled by a large capacity controller.
$800 on inverters has saved me $2,000 on initial costs of appliances
Appliances are 90L fridge, 90L freezer, 34L microwave, .9L electric jug and a 2.4kw vacuum cleaner (just replaced by a cordless unit)

No gas in bus/motorhome as solar is free and endless but I gotta buy and keep buying gas!

I was just researching solar generators 2 nights ago and have just come across this, handy find!

Been wondering how to incorporate this feature into the underground idea without giving away the location. Come up with no good ideas yet

Depends on your budget.
Good second hand panels $50.
Two good 200 amp 12 volt batteries or 4 x 6 volt trojan L16H's  $3,000
Good midnite reg $850. Plasmatronics reg $400.
Latronics invertor $1 per watt Ie. 2000 watt approx $2,000 and has a 10 year repairable life (made in qld)

I lived off grid in a motorhome with wife & 2 kids for a 6 month around oz trip. What I learned about electricity management was that you need to change the way you use and need electricity. Batteries are heavy and expensive and easy to damage. If I was living off grid again, which I intend to soon, I'd have lots of pv panels and not much battery.
More panels than you need can still charge and run your system on cloudy days. A small petrol generator will take care of the worst rainy, cloudy days. During the day I'd use the excess panels to chill a chest freezer way down and have it switched off at night and the same with a fridge. I'd keep a 200L gravity cistern pump filled each day so I didn't have to run the pumps at night. I'd use (as I did in the motorhone) 12v lights so as to not run an inverter thru the night.
I agree with arkane about just use 240v appliances off inverters, just make sure you've got enough headroom on the inverters. 240v appliances are easier to get hold of.
Then of course, keep the fridge and especially the freezer in the coolest spot possible, insulate your dwelling, have a celler etc.
Just my thoughs and experiences.....

Plug in timers are what we use at sons place. Switches freezer off at 7pm and on at 12midnight for 15 minutes , off again until 6 am. Lining larger freezers with frozen water bottles also saves BTU's as well. So many led light configs now there is really little need for 240 lighting.

Around the top and two sides of my fridge and freezer I have put 5cm of Styrofoam, it has cut power consumption to less than half it was. the batteries only drop 2% from sundown to sunup now and that is in the winter!

Styrofoam is a much under rated product. :)

That does work well, but you have to know where the condenser plates/grids are on the fridge as you don't want to insulate them. The last fridge I went to do this with had them all down the sides so no go in that area. Old fridges had them at the back in plane view, that was easy.

I checked first, they are on the back so no Styrofoam there or on the front
Our new kitchen fridge has the heat radiators on the sides but the old style bar fridge and freezer  have the radiators at the back still!
