Hi, in the case of comms failure between master and inverter, is the Fronius inverter automatically disabled or kept with the last known setpoints?
Thanks, I have had exactly this same situation. So good to know all is well even if it is not present on the network.
However, there are then gaps in solar produced, a bit irritating.... why would the comma fall over. I have not had this problem and all of a sudden it has surfaced. I have found that my external internet comma has been erratic but it should not affect the local connection between ccgx and fronius primo?
The comms are not required for the operation of the Fronius inverter.
Once the Multi is programmed with the AC PV assistant, then it will raise the frequency to cut out the inverter regardless of if it is connected or not.
The Fronius will continue to produce as well, it does not require the comms to operate. It will run until the frequency exceeds its programmed spec (usually ~52hz).
