In the mountains, we also recommend propane for the startability factor, but if weather permits, or they have an indoor gen setup, Biodiesel can be very environmentally friendly. I've seen some old Lister Petter diesel units that just seemed like they'll never stop. Not a lot of electronics to

I'm not a generator guy but had to supply a couple of generators for a contract last year. I had a look at the Generac EcoGen and liked what I saw. Additional reading confirmed that others felt positive about the EcoGen so I got a dealership. One year later here's my take on it - and unfortunate

Jay, Other than the two items mentions, lower BTU's and altitude derate, I know of no other reason for LP to have lower output. If it is in the budget, I always oversize a generator after derating so it does not operate above 70% load. I do this for longer engine life as I imagine a fully load

We recommend propane to all our clients in New England simply because in the winter a propane gennie starts without the need for a block heater or special diesel storage. Reliability is preferred over price when it comes to needing charging after a week of cloudy, snowy weather. Many of my clien

Jay, In addition to what Dan has said, 1 gallon of propane has about 35% less BTU's compared to 1 gallon of gasoline. So the propane derating must be added to the altitude derate to determine generator output. Larry Crutcher Starlight Solar Power Systems On Jan 30, 2013, at 1:32 PM, Dan F

Jay; The "standard" seems to be 2-3% derate for every 1000 feet above sea level for gasoline, diesel or LP gas generators, and supposedly more like 5% for natural gas. (in general we don't work in areas that have natural gas service, we only do off-grid). So the propane de-rate for altitude is no w
