It’s certainly not for every situation, but I have had some experience with using [used] 6kw diesel light tower generators as backup power. These things are ubiquitous in the construction industry and are almost all powered by super durable Kubota or Mitsubishi 3cyl liquid-cooled diesels. They are definitely on the small end at 6kW, but even at 10,000 ft I have had no problem providing a full 4kW+ of battery charging power. One of my customers is an Iron Planet auction junkie and sourced one of these things for his PV system here in Colorado. It’s a summer-only solution, as the unit currently lives outdoors, but I was impressed with the performance. I have another one at a different site and it has proved to be reliable, quiet and easy to start. Downsides are obviously that they are most affordably sourced used from an auction house, the controls are pretty basic, and there is the whole issue of it coming mounted on a small trailer with lights. But some customers like that sort of thing, and it’s pretty straightforward to set up a generator controller for 2-wire start capability.
