There are various types of lithium batteries on the market, each utilizing different BMS (Battery Management System) communication protocols. If you are unable to view battery information on the APP or display screen after connecting the inverter with the battery (as shown in the photo Below),

It is very likely due to a communication issue between the Battery BMS and the Solar inverter.

This post may help you solve this common problem..

Quick Solution: You can try to disconnect PINs 1-6, leaving only the pins 7 and 8.

Here is how to do:

Position the RJ45 Ethernet Wire with the copper pins facing up.
Cut off wires of PINs 1-6, leaving only PIN 7 (Brown/White) and PIN 8 (Brown).
Then try reconnecting the inverter and battery to check if it is working.

If it is still not working, here are more suggestions:

Try restarting the device.
Power off the unit, wait a few seconds, then power it back on.
Check Physical Connections:
Ensure that the connections between the inverter and the battery are secure and correctly wired.
Confirm that there are no loose or disconnected cables.
