Dear Martin, the peak wattage should also have a time with it like 3000 Watts for 20 seconds. Unfortunately this is often "forgotten" and even if it is given it may be more to do with the marketing department than the engineers - big numbers sell kit! Personally I would not use anything with a rating of more than 1800 Watts. Watts = Amps x volts so if an appliance is rated in amps I would advise that you use 240 as the volts part. It is normal practise to assume inductive loads (those with coils in them like motors)demand a starting surge of 20% more than the rated consumption so that may help you. However if the surge is longer lasting than the surge time of the inverter you may still have problems. Much safer to stick to 1800 Watt maximum appliances. Tony Brooks
