David, no wonder Liemack went as a business into the distance and belly up.
Liemack were a good fridge, but they consume more than twice as much power as any other battery compressor fridge. In a 24 hour controlled environment
test, the average power consumption by Danfoss powered 12 volt compressor units averaged about 2 amps an hour over 24 hours. The Liemack used a whopping 5.6 amps an hour over 24 hours. The reason is the Liemack uses a Mitsubishi 240vAC powered compressor, and uses an invertor to convert the 12vDC to 240vAC. NO, one
BP SX60 solar panel would not run your system. You would need three (shock horror). As for them not recomending a deep cycle battery is completely wrong. A standard cranking battery is *NOT* under any circumstances designed to be used like a deep cycle battery, and after probably 50 cycles of deep cycling, the battery would be ruined and giving you very poor performance.
Looking at the long term and how
young your children are and how much longer you expect to go camping, I would highly recommend you sell your Liemack refrigerator, get rid of one of the batteries you currently have to take you down to two, install a proper deep cycle battery for the second battery and a proper charging system mounted in your vehicle to charge that second battery to full capacity. You then run a 6mm twin cable down to the back of your vehicle, and terminate it with a small Andersen plug. On your camper, you put a second Anderso/en? plug wired with 6mm cable into your camper electrical system. You then get a Danfoss 12vDC powered fridge like the evaKool which has *great* insulation, and is properly built in Australia for our climate www.evakool.com.au and then get a
BP SX60 solar panel that would run the evaKool fridge.
Overall, this would still be a cheaper option than buying a Honda EU1000 generator and running it.
