Sunsynk Fault Codes

I live in the UK, and I only ever get this error when Sunlight causes the battery to reach it's capacity. (It never happens on a dull day!) I've got an 8kW hybrid inverter and a SunSynk wall-mounted 100Ah Battery. I don't want to untick "BMS_Err_Stop", if possible, as I would rather have the safety net of shutting down if there is actually a problem with the battery. Does anyone else get this issue solely when the battery is at 100%? (PS: I know I'm not a registered installer, but it was fitted by a national MCS installer who's aftersales support is zero. I am, however, an accredited Electrical & Electronics Engineer with an additional Accreditation in Telecommunications) Below is event list showing SoC at every occurence.
