Need help?
Do you have a question about the UP2000-HM6022 and is the answer not in the manual?
Questions and answers
Good Morning...I newly bought my Epever WIFI 2.4 G RJ45 D module and connect to my UP3000-HM10022(RTU) ...but i cannot communicate..there is no sign of communication..even the small green light is not lighting..there some remedy for this problem...thank you...
1. Check Connections: Ensure the WiFi module is properly connected to the DB9 interface of the UP3000-HM10022 RTU. Verify that the cables are secure and undamaged.
2. Power Supply: Confirm that the WiFi module is receiving power. The DB9 interface provides 0.2A/12V power, so check if the RTU is powered on and functioning correctly.
3. Indicator Light: If the green light is not lighting, the module may not be receiving power or could be faulty. Try reconnecting it or using another module if available.
4. Circuit Breakers: Ensure the battery circuit breaker is closed and that the inverter/charger is turned on. The system must be running for proper communication.
5. Inspect for Damage: Look for signs of corrosion, loose terminals, or physical damage on the module and RTU.
6. Reset the Module: If applicable, restart the WiFi module and RTU to re-establish communication.
7. Check Configuration: If possible, verify that the WiFi module settings match the RTU’s communication parameters.
If the issue persists, consider replacing the module or consulting technical support.
