D. High-Speed Cooling Fans. When the temperature inside the inverter
exceeds a preset limit, the Cooling Fan automatically turns on to cool the
inverter. When the temperature reduces, the fan turns off.

Determining the DC Power Requirements
Powering multiple appliances from the high-power ML900-24 inverter requires
a 24 volt battery. To calculate the approximate power in amps a 24 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 20. For example, the continuous AC load is
900 watts. The current (amps) is: 900/20 or 45 amps at 24 VDC.
Add to the load any DC appliances that may be powered by the battery bank.
Sizing the Battery
To determine the minimum battery bank ampere-hour rating that you
will need to operate appliances from the inverter, and any DC
appliances powered by the battery bank. Follow these steps:
