48v ESS system. Grid spikes and error light flicker (video)

Hi everyone

I'm having a bit of an issue with the grid going crazy. Here is a video of it in action

https://youtu.be/3ahDv2VilDo

This doesn't happen when I set the SOC to 100% and have grid power.

This is the setup

UK Mains power

1 X Victron Energy Quattro 48/15000/200-100/100 230V VE.Bus Inverter/Charger
1 X Victron Lynx Power-In
1 X Victron Lynx Distributer
1 X Victron Lynx Smart BMS 500 (M8) Battery Management System Bluetooth
1 X Victron Cerbo GX
1X Victron Touch 70
1 X Victron Interface MK3 - USB
1 X Victron SmartSolar MPPT RS 450/100-Tr

8 x Victron BAT512120610 LiFePO4 Battery 12,8V/200Ah Smart (for 48V 400Ah –
20KWh) (4 in series then in parallel)

Does anyone know what I can do? Thanks

Huge power surge issue with Ess on a 48v 15000 quattro: Issue Now Fixed

Hi Some of you might have seen my post with the video below using the 48v quattro 15000 in the UK. This issue has now been fixed with a firmware update on the quattro. I had to call my dealer to get the password to upgrade it using the victronConnect.exe using the ve.bus usb interface.

I have noticed that they have removed grid compliance A from the system for the UK.

Hope this helps anyone else having this issue.
