When you get the Ground Fault, does the Barc continue to operate or halt ops until cleared?  I had the same issue with my Hawkes Bay, replaced the board & toroids twice.  The Manual says when you have a Ground Fault, the system will stop until the Fault is cleared, but in my case, the Hawks Bay continued to produce power with the error message still displayed on the screen.  I even connected a different set of panels using separate wiring to the HB, would still get intermittent Ground Faults.  Seemed to happen most often when the sun initially came up in the morning. Lastly, I ran the same PV/wiring thru a Classic controller next to the Hawkes Bay and never received a Ground Fault!  Anyway, I just turned off the Ground Fault in the software and soldiered on.  My 2 cents

You are correct, the Hawkes Bay and Barcelona Ground fault code does not cease charging, this is a defect in the code.  Also I found out the AF/GF circuit boards are "tuned" to the specific cores they are shipped with, they are "matched".  Just swap the board and not the cores that go with it and bam, false alarms.  Since the original programmer has left and they have no one to continue to work on it and fix the bugs it is what it is.  I heard management is going to try and hire a replacement but I have no idea what the status is.  That being said it will take time to get him or her up to speed on the MPPT code.  I don't expect any updates for a while...

Thanks James for the info . I appreciate the reminder about the AF/GF board & toroid 'pairing'.  Ryan had mentioned that when he replaced my initial AF/GF board, but I don't think it's common knowledge as it isn't specified in the current manuals.  Good to see you on the forum!

AAPilot
Same issue as yours

[mahendra]

So, I did promise updates, guys.

So here they are, Rosie, Barcelona and MNGP2 updated to the most recent with five(5) Midnite powerflow batteries in closed loop communication,

Let me know if anything seems wonkers.

Looking good! That dolly for the battery stack seems to be a custom fit.

Yea ,we did some welding ,bolting and stuff to get it together.We appreciate some  ease of cleaning in those corners.
Readings seems spot on so far .

We will be adding Solar assistant soon.Picking up the CAN to USB cable tomorrow.
Don't make that mistake when ordering, ensure you add cable to cart.

The nuisance ground fault trip did not reoccur since the updates and adding the powerflos .Hope it stays that way.

[mahendra]

Well we added Solar assistant ,
But it's not going as well as I would expect.
No data on Solar assistant from Rosie, we swapped can to usb adaptor but still the same

[mahendra]

Update!

Rosie, Barcelona and power Flo finally functioning with Solar Assistant.
Thanks Ryan@midnitesolar.
We had some hiccups but got there.
