The power rating of inverters is specified as follows:
• Maximum Continuous Running Power Rating
• S urge Power Rating to accommodate high, short duration surge of power required
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
"DeFinitionS"

inFo
The manufacturers' specification for power rating of AC appliances and devices
indicates only the Maximum Continuous Running Power Rating. The high,
short duration surge of power required during start up of some specific types
of devices has to be determined by actual testing or by checking with the
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-
mended against each which is a Multiplication factor to be applied to the Maximum
Continuous Running Power Rating (Active Power Rating in Watts) of the AC appliance
/ device to arrive at the Maximum Continuous Running Power Rating of the inverter
(Multiply the Maximum Continuous Running Power Rating (Active Power Rating in
Watts) of the appliance / device by recommended Sizing factor to arrive at the Maxi-
mum Continuous running Power rating of the inverter.
