For Inductive Load
If connecting with inductive loads (e.g. Compressor, Pump, old CRT TV, Refrigerator, Ice conditioner, Air conditioner, Relays,Fluorescent lamp, Vacuum cleaner), please choose inverter whose rate power is 3-7 times higher than the load's rate power. For example, for a 150w refrigerator, please choose a 1000w inverter or higher; for a 800w air conditioner, please choose 2500w inverter or higher.
For Resistive Load
If connecting with resistive loads (e.g. Computer, LED TV, Fan, Scanner, Fax machine, Duplicator, Sound system, Juice extractor, Heater, Electric cooker, Coffee maker, microwave, crock pot), please choose inverter whose continuous power is a little higher than the load's rate power. For example, for loads near 700w, it's better to choose inverter with continuous power more than 800w.
