I am the only one in my hanger so there wouldn't be anyone else monkeying around in there ie. leaving a jacket on the generator.
I also have an exhaust tube connected so that the generator fumes exhaust to the outside.
I usually run out to the hanger in the wee hours in my Pj's, start the generator, hook up the pre- heater and then come back home to drop kids to school etc... I'll return 2-3 hours later and by then the oil temp is up to 100+ degrees. Good to go.
I don't feel I'm being unsafe by leaving the generator running unattended. I did it all last year. I'm just looking for a way to avoid the Pj run
I like the idea of the 12V battery with the inverter but I don't know how long it would last, plus how long it would take the solar charger to re- charge it.
Would 4 car batteries in parallel last 3 hours on the pre-heater?
Thanks for the ideas though. I'm still digging.
