How to fix firmware error on Hoymiles HMT-1600-4T Inverter?
- BBrittney LopezAug 13, 2025
If you encounter a firmware error with your Hoymiles Inverter, first verify that the firmware is correct and attempt to upgrade it again. Next, check the communication between the DTU and the Hoymiles monitoring system, as well as the communication between the DTU and the microinverter. After checking the communication, try again. If the problem persists, contact your dealer or Hoymiles technical support.
