Re: Solar Powered Refrigerator
morning gary- boss has had me having a go at reinventing the wheel- used a 3.5kw wall mount unit-using 12v batteries via a 2000w inverter to create 240v to power the inverter circuit, doing this we were drawing 2 amp on the 240v circuit (approx 40% duty-maximum current 5.1amp on 240v mains)- but 12v off the battery its dragging 120amp, used a 4x4 battery rated for 700amp load, 25 amp continuous- it ran the compressor for about 10 mins, he also wants to charge the batterys via a dynamo coupled off the cond fan- thats the problem,also a changeover panel to revert back to mainswhen the battery was low- currently the project has stopped
