F51 Battery temphigh

Had this fault on a 3 fase 12kw inverter. And it's bee quite for about a week but this morning 6am it pops up twice again and it shuts down I have 2 x 15jwh Felicity batteries connected via 485 BMS connection. I've lover the charging current from 160Anps down to 120Anp, to see if it would change anything.
