I am currently proposing the integration of a single Quattro 24/8000/200-100/100 unit. I am curious if anybody knows how these units operate during "current overloading" conditions from a DC standpoint. So if the unit is set for maximum 200A max DC (DIP SWITCHES) charging and the units is overloaded (Dead Battery, Heavy Auxiliary Loading, etc), does regulation set in and begin to reduce the charging voltage on the DC terminal to reduce current? Does it sort of just cycle back and forth keeping current below the maximum setpoint or can the system go into 100% overload and "open" circuit the DC terminal? I've read that most chargers follow a 3 step charging profile initially keeping current constant by modulating the output (varying DC) to achieve constant current profile as the battery begins to charge up and battery impedance decreases over time. Curious if these units will do the same or can i dump the unit during overload....
And can somebody explain the "Inverter" power specs on the data sheet?
Continuous output power at 25C 8000VA at 3:1 crest factor
Continuous output power at 25C 6500W
I'm lost with those two specs. I understand crest factors (AC perspective) greater than 1.4 are due to non linear loads (rectifiers, etc) but what if we have a purely resistive load with a power factor of 1.0... Can we get 8000W since 8kVA = 8kW when PF = 1.0? Totally lost on this one.
THanks!!!
