I am a volunteer firefighter and hold a degree in electrical engineering. The shenanigans with their shunt resistors, and ensuing melting cables, is in my view criminal. Any engineer worth their salt would recognize pushing 600W through a bunch of small cables with no contingency if some of them have failed is just asking for trouble. These assholes are going to set someone's house on fire.

I hope they get hit with a class action lawsuit and are forced to recall and properly fix these products before anyone dies as a result of their shoddy engineering.

To emphasize this point, go outside at noon in the summer and mark off a square meter on the sidewalk. That square of concrete is receiving about 1000w from the sun.

Now imagine a magnifying glass that big (or more practically a fresnel lens) concentrating all that light into one square inch. That's a lot of power. When copper connections don't work perfectly they have nonzero resistance, and the current running through them turns into heat by I^2R.
