The product's nameplate should list both the operating amps and the maximum amps.
When you do not have access to the nameplate for reactive load products then as a guide use the rated Amps or Watts multiplied by 7 to arrive at the total required at start up. For example - a 200W power tool will need a 1400W inverter a 60W fridge will need a 420W inverter and so on. It is also recommended to get an inverter with at least 30% more than your needs. Australian Standard AS4509.2 states a surge factor of 7x the continuous power should be used for electric motors water pumps fridges air conditioner and washing machines. A surge factor of 3x should be used for kitchen appliances halogen and LED lights and other electronics equipment.
