I use Onan more than Kohler but water cooled and low RPM are the ticket.

From: [email protected] [mailto:[email protected]] On Behalf Of Randy Brooks Sent: Monday, January 24, 2011 1:16 PM To: Wrenches RE Subject: [RE-wrenches] Generator for off grid Fellow Wrenches, What generator manufacturer are you currently recommending for off grid use? A Kohler 18RES (LP, 3,600 rpm, air cooled) a customer installed last year has already failed after 370 hours of use during 6 months of construction and winter occupancy. It consumed enough oil to cause the low oil shutoff to activate, and the generator controller board is fried. The owner is still negotiating with Kohler, but Kohler has said they will not support any of their generators used off grid. The owner is looking at a Cummins Onan 20 kW GGMA (LP, 1,800 rpm, liquid cooled). Any suggestions would be appreciated. Thanks, Randy Brooks Brooks Solar, Inc.
