Problem with EasySolar-II GX Installation - Goes OFF when Grid is disconnected

We have recently started facing issues with an EasySolar-II GX installation which has been functioning well for the past 3 years. The system is configured to automatically switch to solar when the grid is not available.

The system goes off each time the grid is unavailable.

The batteries all seem healthy and are charging but there's a constant battery low alarm.

The GRID input is constantly abnormal, with values indicating negative input most of the time.

Here's the console reading for the MultiPlus-II parameters

I will gladly provide any more information to get assistance with this issue.

Thank you.

What batteries do you have? Is there a fuse between have you checked it?

If anything it is likely the batteries or connection to them that is not well.

Is this set up as ESS or as a UPS? If you manually disconnect the grid, isolate the pv and run just from batteries, how quickly does the voltage drop on them?
