RE: (ET) e12 hybrid?

["Phil Trice" <pctrice purdue edu>]

Jeremy,

    I have much the same sort of plan. My tractor is a lightweight, with three 80ah 12volt batteries. It's always been a bit short on capacity. I'm in the process of building an onboard APU using a small, 2-cylinder engine coupled  to a 100A alternator. As Max suggested (in another message), I will derive the 38 volts by controlling the field winging on the alternator.

    This is a small part of a much larger project, so it is still on the drawing board. I'll post pix and progress as it happens.

I just purchased an e12 unseen for 350 dollars, but in good condition with a front mower and snowblade.  I produce all my power from solar and wind supplemented by generators, and it is difficult to supply the 10 KW to fully charge the batteries.  I plan to charge my batteries from a small 3 horsepower turning a 60 amp alternator and controlled for 36 Volts.  When batteries are low, turn on the generator, instead of pulling in to plug in just charge while you mow.  I'll post my progress.
