Hi Pedro
I just spent 2 weeks away without plugging the 80lt Engel into 240 power.The first week the Optima and the 2 37w solar panels did the job,didnt use the trailer batteries until staying at CraigEs,then only at nite.Had the fridge at its coldest setting most of the time(only turned it down at nite when camping,at Craigs it was on full).The beers were coming out with a hint of ice,just the way I like them
There is no low voltage cutout on the Engel,I have Drivesafes new low voltage cut out on the 12V supply to the fridge/acc circuit.Contact Tim for more info,mine is a trial unit.Only cut out on the last day as somebody neglected to turn the fridge down before crashing out for the niteI blame MR EMU bitter and MR Black BEAM
