PORTABLE GENERATOR QUESTION

The inrush of a microwave oven is formidable. I'll hazard a guess and say there isn't a 2,000 watt generator in existence that does not give a tiny grunt when a thousand watt microwave starts up. If I can tell my commercial 1,875 watt LG startup on a 12,500 watt Kubota / Kato, it raises my eyebrows when an attempt is made to squeeze a reserve margin down to near zero.

What happens on a hot day? Higher altitude? Higher percentage of ethanol? Engine gets out of tune or worn out? Batteries are low and the converter is robbing the kitty?

Points to muse for sure...
