What solar/batteries set up for camping?


What do you guys run, and how long can you run it for?


Just after some real world experience on some set ups for remote camping. i  atleast want to run 80l engel on freezer and a 40l engel on battery/batteries for  about 10 days.

will have a generator for back up.

What's your budget?!

running both of those on freeze will suck a battery dry pretty quick. Ideally, you would want a battery for each of them, and a minimum of 100a/h. Probably bigger for the 80l, maybe 120a/h. You could probably alternate a decent size 120w-160w)solar panel between the 2 batteries, but in an ideal world, 1 for each battery would be the best bet. A little generator is good back up for the cloudy days, or even just run both freezers on it whilst you give your batteries a boost charge every 3-5 days.

 Per above, one battery would really be working hard over 10 days. 

160w of panel, 150-200 ah of batteries and a 2000w generator with a 15 amp charger for if it is cloudy for a day...

 On my camper 4x4 i run 2 x 130watt solar panels into a ctek dual feeding 2 x 120a/h AGM's . The ctek also links into the dual starter batteries and alternator of the car so it takes a charge while driving and can charge my starters with the solar .. i run a 110lt waeco plus a heap of led fllod lights and strip lights , multi usb outlets and cig lighter attachments for bits. . Ive never had them drop under 12.5v even when traveling for extended trips off grid. . If it was really cloudy id expect 5 days of power (but id start the car before that and charge)

 You can calculate the numbers all day, but there are so many variables such as moving panels or not, cabling etc.

For me, 70L Evakool on freeze, 120W EBay panel, 120ah AGM almost does it with sunny days on the boat.

If it was practical to follow the sun you get maybe 30% more power.

On the boat though most days it gets a top up anyhow

Thanks for the info guys, what I was thinking is

ive got 2 x 120 agm batteries one is part of a dual battery from alternator, other on cteck with 120 solar.

run the 80l on cteck on solar on freeze  and just run the 40l as a fridge on the dual system on the car  and maybe crank it up to freeze if need be 

then have a generator run for couple hours at night to  top up freezer battery
