Hello good folks in the RE world! An off grid customer of mine has a VFX Quad Stack wired exactrly like page 20 in the FX manual, including the X-240 balancing transformer
connected to the panel output legs. He has been feeding it with two legs of a three-phase diesel generator. IS THIS A COMPLETE NO-NO??? HE KNOWS THAT IT WILL RESULT
IN AN UNBALANCED GEN OUTPUT, BUT SO FAR IT HAS BEEN WORKING OK, BUT WITH THE FOLLOWING GLITCH: WITH THE GENSET OFF------THE OUTBACK POWER PANEL
OUTPUT BUSSES ARE BOTH ENERGISED ONLY WHEN THE x-240 BREAKERS ARE ON. AS SOON AS THE GENERATOR STARTS (AGS SYSTEM) THIS 20 AMP DOUBLE BREAKER
SEE PAGE 20, X-240) TRIPS IMMEDIATLEY, LEAVING HALF THE LOADS WITHOUT POWER (NO OUTPUT FROM THE LEG 2 INVERTERS TO THE HOT 2 OUT BUSS) i'M BAFFELED,
COULD SOMEBODY PLEASE EXPLAIN THIS SITUATION TO ME SO THAT i CAN HELP THEM OUT? Another electrician told them that a buck/boost transformer (on the gen output?)
would be the fix. Thanks a bunch in advance for your help in this serious matter. Nick Houser Off Grid Services, Powell River, BC
