Generator conected to 3 off Quatro 8000 in 3 phase , I gave a big problem no one can solve , we are OEM not a solar installer and use this Quatro in our packing machine. Problem we have 3 quatro's are conected to VFD 45 Kw drive a 45 kw motor to pump , VFD starts up on 6 amps per phase no prob , when generator 40 kva get conected and running to quatro inverters do not want to except it , when current is measured between quatro and VFD when the switching over to generator needs to happen we measure 140 amps . If one supply VFD from another generator 3 phase and remove the quatro supply the inverters except the 1 st generator and the current without load sit at 4 amp per phase. What can be the problem for the massive diff in current drawn .
