BMS 4 flashing lights.

[Skip62]

Hello, I have noticed this morning that after initially charging from the solar panels the hybrid inverter stopped charging at 89%. I also noted that the BMS had four flashing lights on it. One for each battery. I take it this is a protection system for the batteries when it gets cold. -2 for last two days but yesterday it topped up fine from the panels. Today it’s dumping 1.8kw into the grid rather than charge the battery. Any help would be appreciated. This is the first time I have had any problems since the install in April which I did myself. It’s in my garage which is not heated. I have the All in one 10.4kw system. Thank you. Graham.

Is this a new install? have you tried restarting the bms yet?
