You all are right, it is unlikely that anyone will actually follow this recipe. I guess I’m taken aback that some pretty serious electrical engineering has been turned into a step by step tutorial with little mention of the potential risks.

If an inexperienced person does decide to save some money on an inverter by following these steps (as is implied), it could very quickly turn into “how to electrocute yourself and burn down your house in 10 easy steps.” I would not want to be liable for promoting or hosting such content. Similar to the issue with the “very cool” electric wood burning fad that killed a few people.
