Okay after considering it a while, you only have a L1, L2, N, G poles. Unless there is a winding problem then the issue is phase time. The charge controller needs input to be in a range of 60 cycles per second +/- x cycles per second. If your idle speed places your alternator outside this range then there will indeed appear to be a leg imbalance to the Charge controller that's expecting the 60 cycles per second range. This leads back to engine idle control speed. It may appear to idle up and down to the load but that doesn't mean it's within the proper cycle range. If it's out of sync of the 60 cycles per second expectation it will create an power imbalance between itself and your charge controller/inverter. The inverter/charge controller should not accept the generator current if this is the case and give you an under current, over current warning indicator.
