In the past few days Our Quattro 48v has randomly shut down twice and when you try to restart it, the unit comes on and then shuts down after a few seconds.
We use a Cerbo GX with DVCC enabled and a Batrium BMS with Canbus connection. We don't run any ESS assistants, however both times it shut down I noticed the cerbo touchscreen display said ESS#4 at the bottom of the main page. Last time cutting the power to the cerbo cleared this message and the quattro restarted ok but today that trick is not working.
I am at a loss to what the problem is so any ideas from the community would be great. Many thanks
