We are using PVI-RS485-MODBUS to connect our inverter with our IP network, two inverters are connected in series with PVI-RS485-MODBUS. We are NOT getting reading of our very first inverter connected with our PVI-RS485-MODBUS, however, we are getting result of the inverter connected at the end i.e. II nd inverter. Our Power ON , EPRON and RS485-ARORA all three LEDs are GREEN and 4 th LED for "RS 485 - MODBUS" is RED. Please advise to resolve the issue.

Comments

  • Verify the last inverter in the series reistor is set to "ON" via the dip switch and the other set to "OFF"

  • Ensure that both inverters each inverter is assigned their own address.

  • Verify that the RS485 cables connected to the units have continuity.

Yes i admit that We are not getting reading of our very first inverter but however, we are getting result at the end of the inverter.
