[RE-wrenches] Strange conflict between FM100 and VFX3648 Charging.

[Jay]

Hi John

Do you mean 30 amps dc or AC from the inverter?  

Regardless I can only think the issue is programming. 

Is this a new issue after new equipment or ?

We had a problem with charging going between 0 and approx 30 amps DC. The current would climb up in about 10 seconds and then slowly go back to 0 in about the same amount of time and then repeat.  For some reason when we unplugged the FM100 from the HUB, charging would resume at about 40 ADC continuous from the generator..  This happens when the sun is out and when dark so the solar input is having no effect on this strange behavior.   Any ideas?
