Looking for a portable back up generator. Natural gas is not available and wife doesn’t want a large propane tank so looking at larger portables. Generic has one that is rated for 18kw and the largest Honda is rated for 10kw. They are close in price. Generac would give more headroom for the house heat pump and a load of wash, but I am more familiar with Honda. Anyone have any experience on the Generace portables? Motor on the Generac 18kw unit looks to be a v twin made in the USA. TIA.
