The power rating of inverters is specifi ed as follows:
• MaximumContinuousRunningPowerRating
• SurgePowerRatingtoaccommodatehigh,shortdurationsurgeofpowerrequired
during start up of certain AC appliances and devices.
Please read details of the above two types of power ratings in Section 2.1 under

The manufacturers’ specifi cation for power rating of AC appliances and devices
indicatesonlytheMaximumContinuousRunningPowerRating.Thehigh,
short duration surge of power required during start up of some specifi c types
ofdeviceshastobedeterminedbyactualtestingorbycheckingwiththe
manufacturer. This may not be possible in all cases and hence, can be guessed
at best, based on some general Rules of Thumb.
Table 2.1 provides a list of some common AC appliances / devices that require high, short
duration surge of power during start up. An “Inverter Sizing factor” has been recom-
