Thanks for that. What sort of power generator should i be looking for?
I would recommend a 6kva that's 4800 watts, it is measured in its max wattage not continuous so will be running at less than 4800 watts.
currently I am running a 5kva that's 4000 watts and to be honest it does work well but there is noticeably more power when I run it from customers electric.
