good day all your clever people. I got a Axpert king inverter (5kWa) with panels working for years now. Upgraded to Pylontech batteries and now i am experiencing problems where my PV switch off once my battery hits 100%. i then manually needs to go and disconnect my strings and re-connect to get my PV going. I heard that it might be a problem with the firmware. currently running  71.50 firmware and looking for 71.94 or greater.

anyone know where i can find this and if this will resolve my problem?

It's a firmware problem, but I am not aware of any version that fixes it.

I'm fairly sure it won't resolve that problem, though 71.50 is quite old, and there were definitely some solar charging problems with the early firmware versions. So it's certainly worth a try.

If you're using a direct-to-BMS cable, it's probably also worth updating the removable display firmware. 02.70 is available from this post:
