A new site with CCGX, Multiplus-II 48/5000, MPPT 250/100 and self managed lithium battery. The Multiplus wont turn on unless the CCGX is first unplugged. The CCGX can then be plugged in and the system works as expected (System is on VRM) until the Multi is turned off, then the CCGX needs to be unplugged again to power up.
Look forward to thoughts

Hi @David,
Is there a comms link between the battery and the GX device?
If the battery BMS is reporting 0A discharge current limit, then it will instruct the Multi to not start.
Hi @Guy Stewart (Victron Community Manager)
Good to hear from you. Nope, I checked with the installer and they haven't put anything in the comms ports from the Powerplus batteries back to the CCGX. The system is on VRM if i can send you the link?
