honestly, for powering the fridge its kinda pointless as the fridge cycles with demand and you would have to run genny around that. Better to run it off gas.
I had a yami 1000 and it weighted in at 25lbs, held .6 gallons of gas and would run about 12 hours and charge my batteries, and is plenty of juice to power most newer tvs, LED/LCD. Also was great to start up on cold nights when furnace was off and on, my batteries would be chagred in the a.m.
