Determining the DC Power Requirements
Powering multiple appliances from the high-power ML3500-24 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 2000 watts. The current (amps) is: 2000/20 or 100 amps at 24 VDC.
Add to the load any DC appliances that may be powered by the battery bank.
