SECTION 2 | General Information
• High intensity discharge (HID) lamps like Metal Halide lamps. These may get damaged.
Please check with the manufacturer of these types of devices for suitability.
• Some fluorescent lamps / light fixtures that have power factor correction capacitors.
The inverter may shut down indicating overload.
2.5 POWER RATING OF THE INVERTERS
The continuous output power rating of the inverter is specified in Active Power in Watts
for resistive types of loads like heating elements, incandescent lamps etc. where Power
Factor (PF) = 1. The Surge Power rating is for < 1 sec.
Non resistive / reactive loads with Power Factor < 1 like motors (PF = 0.4 to 0.8), non
Power Factor corrected electronics (PF = 0.5 to 0.6) etc, will draw higher Apparent Power
in Volt Amps (VA). This Apparent Power is the sum of Active Power in Watts plus Reac-
tive Power in VAR and is = Active Power in Watts ÷ Power Factor. Thus, for such reactive
loads, higher sized inverter is required based on the Apparent Power. Further, all reac-
tive types of loads require higher inrush / starting surge power that may last for
> 1 to 5 sec and subsequent lower running power. If the inverter is not sized adequately
based on the type of AC load, it is likely to shut down or fail prematurely due to
repeated overloading.

INFO
The manufacturers’ specification for power rating of the appliances and devices
indicates only the running power required. The surge power required by some
specific types of devices as explained above has to be determined by actual test-
ing 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.

INFO
Les spécifications du fabricant pour la puissance nominale des appareils
et dis-positifs indiquent seulement la puissance nécessaire pour les faire
marcher. La surtension requise (comme expliqué au-dessus) est determinée
en faisant un test ou, en demandant au Fabricant. En certains cas, cette
information n'est pas disponible mais il est possible de diviner, en utilisant
quelques règles générales.
Table 2.1 lists some common loads that require high surge power on start up. A “Sizing
Factor” has been recommended against each which is a multiplication factor to be ap-
plied to the rated running Watt rating of the load to arrive at the Continuous Power
Rating of the inverter (Multiply the running Watts of the device/ appliance by the Sizing
Factor to arrive at the Continuous Power Rating of the inverter).
