E. 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 ERP1500-12 / ERP2300-
12 inverter requires a 12 volt battery. 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 2000 watts. The current (amps) is: 2000/10 or 200 amps at 12 VDC.
Add to the load any DC appliances that may be powered by the battery bank.
