We too have had good success with the 3600 RPM Kohler's. Although we don't care for the battery charging design for the starting battery.

I've have been pleased with the 3600 RPM Kohler's. We've done numerous propane 12kW (which very nicely match up to a dual oven quad stack) and recently did a 17kW and other then a stuck fuel solenoid which was replaced under warranty by the local dealer at no charge they've been fine. It was completely off grid and we didn't catch any flax although we certainly did a few years ago so around here they seem to have slacked on the off grid no warranty thing. It boils down to simple math for me. We've inherited numerous 1800 RPM generators over the year. These customers have gotten $2000+ bills to replace to $5 relays (etc), some times within a few weeks of the last one. These 3600 RPM Kohlers cost less then $4k new including a pad, enclosure and shipping compared to a lot more for the 1800 RPM units. Put that $8k you save into PV and you'll very likely get 10+ trouble free years out of the 3600 RPM Kohlers. I've got several getting up to 5 yrs old now and they are still as strong as they were the day there were installed. They only get a few hundred hr's or year and a 1/3rd of those could be eliminated if the customers were better energy managers. Just my .02 and it may or may not work in anybody else's climate.

Last time I checked ONAN's smallest was 20KW/240 VAC. KOHLER had more smaller units. The lack of choice is due to EPA compliance and then I think the economy, but not sure on the latter. If it does not get too cold or could be installed indoors [as in a shed] diesel gets more watts / gallon but LPG is cleaner to deal with.
