something is wrong with your monitoring.I also don't understand the lack of data logging while I was pulling my 4kW base load... The app simply showed the 50w "import from grid". I'll attach screenshots.
If you pull the 4kw on one leg of the inverter - that would probably do that damage you described.
Are all you heaters on one side of the 240V?
Like I said - at least in my manual it's not documented that load + charging is not monitored. So I would send it back and get a replacement.
Install another set of breakers to protect the Growatt and distribute the heaters even on both sides of the inverter.
Think about it - like you bought 2x 3000W side by side, not one 6000w. You can only draw 6000W on 240V but are limited to 2x 3000w in 120v
