Tips for Troubleshooting Sunsynk Inverter Communication Issues
Hi everyone,I recently faced some communication problems between my Sunsynk inverter and the monitoring app. After some testing, I found a few practical steps that helped me:
Check all cable connections – loose RS485 or Ethernet cables can often cause intermittent errors.
Firmware update – make sure your inverter firmware is the latest version. It solved many unexpected bugs for me.
Network settings – verify your local network allows the inverter to communicate with the app; sometimes firewall settings block it.
Restart devices – a simple power cycle of the inverter and router often clears temporary glitches.
