Enphase › wired control communication
Battery loses communication for a window each midday
reported more than once
Symptoms
- A battery loses communication for a recurring window every day around midday
- One of several battery modules discharges alone even while the house is on grid power, staying on an older firmware than the rest of the bank
- A battery keeps losing its link and needing repeated re-provisioning to stay online for only a day at a time
- Charging is throttled to a fraction of rated output after a firmware update, traced to an intermittent electrical fault at the Gateway corrupting comms delivery to the batteries
