Table 2.0 – 04C Gen Run Amps
04C Gen Run Amps auto starts the generator based on the amount of AC amps needed to handle the load the
inverter is running.
A battery bank with a maximum continuous discharge rate greater than the inverter’s load rate does not need
to utilize the
04C Gen Run Amps setting.
For example, 4 x PHI 3.8 48V batteries paired with 1 x Magnum MS 4448 PAE run no risk of over-discharging
to power the
instantaneous load:
• Max. continuous discharge current for 4 x PHI 3.8 48V = 4 x 37.5A = 150ADC
o 150A x 48V = 7,200 WDC
• Assuming inverter efficiency is 94%*, WattsAC = WDC ÷ 0.94
o 7,200 WDC ÷ 0.94 = 7,660 WAC
• 1 x Magnum 4448 PAE inverter has a continuous power rating of 4,000 WAC, and a 5 second
surge power rating of 5,800 WAC
o 7,660 W > 5,800 W
o The 4 batteries have a higher instantaneous power rating than the inverter
