Understanding alarm code data

[martindell]

New Solis S6-EA1P6-K-L installation and everything (mostly) working fine. I was playing around trying to control export power and now I have alarm code 512 on this sensor: inverter_alarm_code_data. Anyone know how / where I can decode this?

I found this page - but alas no joy: I also searched for 1298 (assuming 512 is hex).

Everything seems to be working, but I'd like to get to the bottom of this. FWIW, the alarm disappears when charging from grid and reappears when the inverter is discharging
