Sequence for charging second battery

I have a AC200 max connected to solar that keeps it charged at 100% SOC. I also have a B230 battery attached. However this is consistently at 0% SOC since it appears the main unit charges preferentially then shuts down. Can this sequence be changed to have both charge together?

Hi @lepat , Sorry for the inconvenience. Can you please see if the B230 has been recognized in the BMS interface?

The B230 is recognized and is listed as 0 % SOC and on standby

Hi @lepat ,Thanks for your confirmation. We have the following suggestions.

1. Change another battery connection port to try
2. Can you try another battery connection cable please?
Cross-test to see if it is a battery connection port or the cable problem.
