[RE-wrenches] Help me understand Gen vs XW

[William Miller]

Friends:

Working yesterday on a newer XW system with a new Kohler RES15 
generator.  This is the first time I have tested the inverter with this 
generator.  The inverter would not maintain a transfer to the 
generator.  After about an hour on the phone with tech support, the tech 
searched previous calls and announced that there is a known incompatibility 
between the Kohler RES15 and a certain version of the XW firmware.  I was 
advised to upgrade the firmware.

I wonder how this can be.  Voltage and frequency even in the moment the 
inverter did try to connect are well within specifications. After some 
thought, all I can guess is that there might be some noise on the AC signal 
that the inverter might reject.

Has anyone else experienced this?  Any insight to be offered?

Thanks in advance.
