Ac200Max with expansion

I recently had an AC200Max with aB230 expansion installed. It appears that the B230 is always at 100%. The AC200Max had gone down to 16%, then I unplugged the B230 and plugged it back in and it suddenly lighted up. I charged the AC200Max from the power grid and now everything is charged up. My question is does the B230 have to be on to be charged and discharged? How do I know if the system is all working together correctly?

Hi @jimmev

you can check on you AC200Max Unit if he recognize a connected battery. If so, it should work. I only have a B300 with a EP500Pro. In order to discharge it, i need to manually turn it on
