Maybe there’s an n^2 algorithm somewhere, maybe the hardware is simply underspecced. Maintaining voltage stability in a system without mechanical inertia (like a generator would have) requires incredibly fast response times, and a system like that should have been verified to actually achieve those.
From the damage that was caused, it sounds like there are no “hardware” fuses built into this system either. That alone should be cause for regulators to take the product off the market.

No, it just sounds like inverter, to which there are two devices connected, one which suddenly draws a lot of current (like starting power tool, possibly the one pictured in the article) and an "electronic device" with switching power supply. When the large current draw happens, the inverter tries to compensate which results in a lot of power transmitted over higher frequency (several tens kilohertz rather than usual 50 Hz). That higher freq bypasses input cap and fries switching power supply.
It doesn’t have to be n² if one unit has to control the others. If a single unit requires base load + 10% per unit you could be in trouble at 7-8 units. That’s more than sufficient for most sales.
If anything maybe they should have a special power wall for large installations, with a beefier CPU and sturdier components.
It’s not uncommon in tech and even to an extent automotive for the premium model to stay one hardware revision ahead of the consumer unit and after a few recalls iron out the reliability problems, after the R&D is paid off on whales, bring it down market and introduce something new at the high end.
That’s both technologically sound and plays on baser behaviors of the well to do (namely, classism). If normal people have the same thing I have then it’s time to sell it so I can feel special again.

What a joke.
