I appreciate the respected knowledge and serious replies given to genuine queries from Tony, but I would like to add that I have a "low frequency 3000 watt 'Powermaster' pure sine wave inverter" installed in my boat. I could perhaps be corrected here but I believe that this particular inverter will take a 200% overload for up to 3 minutes and a 300% overload for aprocimately 5 - 6 seconds, before tripping out. My model is fitted with a torrodial transformer and has many other safety featurs built in, like overheating trip,low battery voltage cut-out etc., I have never had any problems with any of my PC equipment, laptop, auto washing machine - all have "chips" and "microprocessors" Maybe other inverters have similar charachteristics but I am not aware of this. ~Allan~ nb.Pengalanty
