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
