on the second page of this link it says accessories=energy command 30. auto generator start
i think thats the ec-3o ?
We have that Onan control panel in the big brown truck but you cannot use the auto start with lithium batteries, highest trigger voltage for starting the generator is 12.5v which is too low for lithiumís.
Our generator auto starts from a command in the Mastervolt system that controls all the electrical system.
It is a significant improvement to the previous model, on the occasions we ran ours overnight to get air conditioning in our Roadtrek the noise was loud and the bed vibration was like those motel coin operated bed vibrators you used to see.
My Onan 2500 Microlight LP died. I just bought the close replacement. Looks like the QG 2800 but LP and lower KV output. QG 2500 LP it is almost a bolt in fit (I hope) The old one --might get repaired ???? and put on the market.
Any interest out there --I'm in Rhode Island ?
