Solar Charger - MPPT [2], Error code: #29 - Over-charge protection

A well established System is giving these errors this summer , wasn’t last year .

3 solar chargers . Off grid sistema .3x multiplus 2 15000 va . Cerbo gx

Instead of backing off charging the solar chargers trip and alarm .

Pylon tech protocol . 52 volt batteries Felicity solar LFP

Thank you for any assistance

Theres very little information about your system. Since you are using Pylontech i guess its 48V and has a Cerbo? Have you followed the Pylontech integration manual? Have you checked the possible causes for this error?

Presume this is not an actual pylontech but a generic battery spoofing the pylontech BMS? Or is it a genuine Pylon?

You don’t mention a GX or Inverter.
