F29 error after firmware update [SOLVED}
I have a 3 phase system with 3 x 8kW inverters. Everything run fine with the old firmware for about 3 weeks. I then requested a firmware update as the inverters were running 2 different firmware. After updating to latest firmware 419, I get a F29 error and no switch on. If I configure inverters to run independently, all 3 are working.
If I connect the grid to the 3 phase system, I still get the F29 error, but 2 of the inverter connect the load to the input and the third one does not.
A full system reset were performed as well.
Any thoughts on what else I could try.

Thanks to all that answered. Apparently something went wrong with the firmware update on one of the inverters. SunSynk updated it and everything working fine now.
