I've got customers using the Onan 1800-rpm liquid-cooled 20-KW and
30-kW LP residential generators without any problems. While Onan
doesn't exclude off-grid use, the <a

is only 1-year 1000-hours for off-grid applications.<br>

</div>
<div>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.</div>

</div>
<div>The owner is looking at a Cummins Onan 20 kW GGMA (LP, 1,800
rpm, liquid cooled).</div>
<div><br>
</div>
<div>Any suggestions would be appreciated.</div>

</div>
<div>Thanks,</div>
