Been looking at gennys and you need more wattage output than the appliance needs as they take more wattage to start.
Eastern trading for example is 3x 1000w = 3000w... Therefore you would need a min of a 3.6kva genny...
From what i have read is that 1kva = 1000w, therefore the 3.6kva genny produces 3600w.
Someone correct me if im wrong, thats just what i have read.
