7. General Information
Continuous & Surge Power
A Continuous rating is the amount of power the inverter can handle for a number of hours without
overloading. The Surge rating is a brief burst of power the inverter can provide to help start certain types
of load.
Loads Requiring Surge Power
The power rating shown on most electrical appliances is a continuous rating but some appliances require
up to five times this power for a brief period in order to start operating. This needs to be considered
when rating the inverter to avoid overloading it.
When using a microwave oven it should also be noted that the electrical power required from the supply
is around 50% higher than the actual cooking power of the microwave.

8. Operation
Switching On
1. Ensure that the inverter power on/off switch is in the OFF (0) position.
2. Plug the appliance into the AC output socket on the inverter, ensuring it does not exceed the
maximum output power of the inverter
3. Turn the power on/off switch to the ON (I) position.
4. The Power indicator will illuminate green and mains power will be available from the AC output
socket(s). On models fitted with a display the LCD screen will also illuminate.
9. LCD Display & Indicators
Where fitted the LCD display provides additional information to help monitor and manage power from
the inverter.
