Data connection between the battery and the inverter
The BMS of lithium batteries shares status information with the inverter through the communication cable. According to the supplier, this cable is used together with the TommaTech 48V 50Ah LiFePO4 modular lithium battery and provides communication between the two devices.
This cable does not carry power; a separate battery power cable is needed for the power connection. The cable length and connector details are not specified for the product; the datasheet can be consulted. During commissioning, once communication is established, Solar Nexo verifies the battery data on the inverter screen.
Choosing the wrong set for battery cables can affect device warranty and safety. Check the series name, voltage and cable type (power or communication) before ordering; if in doubt, the Solar Nexo technical team will verify the product match.
