Table5.1listssomecommonloadsthatrequirehighsurgepoweronstartup.A“Siz-
ing factor” has been recommended against each which is a Multiplication factor to be
applied 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 size of the inverter).

Switching on/off inverter
The Inverter is switched oN/off using Inverter oN / off Switch (3, fig 3.1).
When the Inverter is switched oN, Green LeD “Inverter” (8, fig 3.1) is lighted.
Switching on /off Battery charger
The Charger is switched oN/off using Charger oN / off Switch (2, fig 3.1).
