Growatt 48V SPF 3000TL LVM restarting/glitching

Was this issue fixed, or is it still pending?
Hi, sorry the system was off while we waited on growatt answer. So I did not update the post yet.

But since yesterday we have been running on a new combination of firmware that seems to have helped the issue. So far after 30 something hours the problem has not happened. But need to run a few more days to confirm for sure.

It's older firmware but it seems to do the trick.

These are the Inverter firmware versions
Board Controller firmware 502.08
MPPT firmware 002.05

Previously the machines wwre running on higher firmware versions. Maybe the combination was buggy
 
Hi,

I have one Growatt SPF 5000ES with a Pylontech us3000 battery. Recently it started misbehaving like in your case. Now I'm keeping the unit in Solar Utility Battery mode. Otherwise it doesn't provide power to the output. It tries to give power regularly, however after only 1 second it gives up. It "healed" itself for several days, however this is unpredictable.
Did your unit glitch after the firmware downgrade?


Thanks!
