Growatt SPF 3000

Hello :)

Looking for some guidance please.

Recently installed a growatt 3000w.

The batteries that are here are AGM and I believe are shot.

However I so happend to be in the room when it started beeping, next thing error 4 popped up but then 19.

It has stayed at 19 now. 

The battery voltage the inverter is reading is 15volts. With the multimeter I am getting 25v at all points even at the inverter terminals.

Not sure why I would get fault 19 as from a Google says no battery.

To add the batteries I feel are shot as the moment I simulate load shedding the batteries can not carry any load at all and shuts down.

But my issue now is I am reading 25V but inverter reading 15V.
