Relatively new to this. I have a B210 connected to a AC240. The expansion battery B210 will not turn on. Is it totally drained? Not sure when it was last working as the two are permanently connected and haven’t taken much notice with only turning on the AC240. Presently haven’t connected to the PV charger to see if it will charge it. Any thoughts?
Hi @Bluewee, It appears that the B210 is out of power. Could you disconnect it and charge the B210 separately? Please try both AC and DC charging.
If you choose solar charging, please ensure that the open-circuit voltage of the solar panels is within the range of 11- 60V.
Additionally, make sure the ambient temperature is within a suitable range.
If you still need assistance, please @BLUETTI_CARE for support.

Hi @Bluewee, We still haven’t gotten your answer, we wonder if this problem is resolved.
We would like to know if the B210 returns to normal after charging and then connecting to the AC240.
Please feel free to contact us if you need more help.
