Experience with portable propane gensets?
Starting to think about getting a portable propane unit. Currently have a Generac 3250 and 5500 gas. The 3250 is adequate for outage needs, but got the chance to "steal" the 5500 at an end of season sale at Lowe's. Have a 400 gallon propane tank for heating and cooking and would be easy enough to extend a line to service a propane unit. Which would eliminate keeping gas around, stabil, etc. etc.
I started looking in the 5-7KW size and didn't seem to find any "propane" units, dual and tri-fuel are readily available. I seem to recall reading that an engine designed solely for propane has hardened valves or something? Anyway have always been suspicious of "multipurpose" things, prefer "purpose" built. With Generac, as an example, propane immediately kicks you into a whole house unit, they did have a 5KW awhile back which came with a 20lb. cylinder, but that had very strict warnings not to adapt for quick connect to larger tanks. My propane supplier has a wall mounted quick disconnect with regulator which they'll install including the line for about $120.
My issue is that I don't want a whole house unit sitting on a pad outside, very willing to drag a genset out of barn and connect to L14 inlet. Several neighbors have installed whole house Generacs and they work fine, other than the ongoing battery/battery charger issues. Don't want to spend that much.
Anyone have experience with multi-fuel units on propane?
Thanks for your time,
