You'd have to satisfy western power that the power you feed back is clean enough from harmonic distortion so as to not cause problems for other users, which means you should be looking at true sine wave inverters rather than the "modified sine wave" ones you normally see. Not only that, but you'd have to find one smart enough to synchronise with the mains. I suspect it won't be cheap. I know nothing of these lister or staromatic generators you mention, but if they can deliver 50Hz AC that'd make your life easier. 3phase would be better and more efficient. They tend to synchronise anyway although you still have to satisfy WPD that the supply meets their requirements. With inductive loads it's more likely the inverter will have trouble. The power factor could be as bad as 0.6 so your inverter will need to be nearly twice the rating you'd expect and with the inductance, you have to make sure the inverter always has a current path available or it could wreck the transistors. If you do have an inverter that can handle it then you may have overheating problems in your inductive loads. You may want to look at wiring up a 12V dc "ring-main" for small electrical equipment. inverting then rectifying seems a bit silly to me, particularly for equipment with external power converters. There are plenty of devices that you can get car adaptors for and there are plenty of 12V devices out there for car/caravan use. As for the kettle, the engine is probably hot enough to boil water or failing that there are 12V kettles in halfords. good luck! -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/linux_adm/list-faq.html
