I just went to the control room to observe something, What I see is not make sense to me. Please help me to understand it.
I have two outback FLEXmax 60 amps charge controller. one Magnum MS4448PAE 4400watts inverter. 8 Rolls 4000 series S460 6volt batteries wired in 48 volts system.
The two outback CC have it's own solar array only connected to the common battery bank.
What I see today is that one CC read in 125volts and ~6amps and out 54.9volts 13.33amps status charging is float.
the other CC read 92volts ~10 amp in and out 54.9volts 19.5amps. the inverter is inverting 40amps at 54.2volts.
When I turn off the second CC the first one jump the amps to 33amps and if I turn on backthe second CC, the first CC go back to 13.3 amps.
This don't make sense to me. The inverter is drawing 40 amps to convert the watts to the house and the two CC controllers is not product more than the current the inverter draw. so why is the first conntroller limit it's currents? the two of them is push out 33 amps, 7 amps less than the inverter draw. yet when I turn off the second CC, the first CC push 33amp by it self. so it is limit it's current flow. Can someone tell me why?
Thank you.
