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

[Jay via RE-wrenches]

Hi John If these are older non A versions you can’t update the firmware without a board change.  Best practice is inverter with newest firmware as master and see if that works  Let us know.  On May 11, 2025, at 8:20 PM, John Blittersdorf via RE-wrenches <re-wrenches@lists.re-wrenches.org> wrote:  It was 30 ADC.  And it happened after adding the second inverter to increase charge rate. I just checked last info on Optics  and found that the 2nd inverter is newer firmware (61 and 68) . I had made sure all other settings were identical on both inverters but didn't look at firmware.  Now I realize the 2nd inverter may be fighting with the first one if they have different firmware.  Guess I better start there and update the older inverter if possible.  Actual charge rate was also half of what it should be based on AC charge current settings.

Is this a new issue after new equipment or ?

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? > > John Blittersdorf > _______________________________________________ > List sponsored by Redwood Alliance > > Pay optional member dues here: http://re-wrenches.org > > List Address: RE-wrenches@lists.re-wrenches.org > > Change listserver email address & settings: > http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org > > There are two list archives for searching.
