Tips
-
This adapter can only be used in conjunction with LMGS Modbus RTU generic cable to achieve direct serial Modbus RTU connection between the inverter and FlexiObox.
-
LIFEPOWR recommends using Modbus RTU rather than Modbus TCP:
-
Modbus RTU uses a direct serial connection between FlexiObox and inverter
-
Modbus TCP uses the local network and might be slightly less stable or less fail-proof
