LG RESU firmware

Hello everybody,
Мy solar system based on Huawei SUN2000L-6KTL-L1 and LG RESU7H was commissioned two weeks ago.
Overall, everything is fine, except for the fact that the inverter keeps the electricity output from the PV close to zero, even though the battery is, let's say only 40% charged. The only remedy is to reset the inverter manually, then it immediately start charging the battery with whatever power is available (up to the set limit).
Although brand new my battery is 2021 (not on the recall list) and I was thinking maybe a firmware upgrade might help. But I couldn't find information about the RESU firmware anywhere. Local LG support is very hard to reach, I'm waiting them for two weeks already to start my warranty.
Can anyone help?
 
Are current transformers part of the system?
I'd expect CT at service entrance, and battery to charge when export is detected, discharge when import detected (peak shave).
Or other configurable options.

Try the installer app to update firmware? The older app is now discontinued, so you will want the LG 'enblock manager' app. The newer app does work with RESU10H Prime that I hooked up today.
