F. High-Speed Cooling Fans. When the temperature inside the inverter exceeds its preset
limit, the Cooling Fans automatically turn on to cool the inverter. When the temperature
reduces, the fans turn off.

Determining the DC Power Requirements
Powering multiple appliances from the high-power EW-1100 / EW-2000 inverter requires a
12 volt battery bank (several batteries). To calculate the approximate power in amps a 12 volt
battery bank has to supply, you need to know: the current, or amps required for powering the
continuous AC load, a shortcut method is to divide the continuous AC load wattage by 10. For
example, the continuous AC load is 1100 watts. The current (amps) is: 1100/10 or 110 amps at
12 V DC.
