Wrenches:<br>
We have cautiously agreed to take on a substantial upgrade and
rehabilitation of a poorly designed 48V off-grid system. Our upgrade
will include a substantial array addition, battery replacement, and
charge controller/safety disconnect replacement. But the immediate
need is for a generator. The 6 year old system has worn out two Onan
residential standby generators; the second one just now (at winter
solstice) has failed completely.<br>
<br>
We expect to keep the two SW5548 inverters. The site is at 7,800'
elevation. The fuel must be LP. The customer is willing to pay for a
high-quality unit. We expect only to specify or recommend the unit,
but not resell it, so there's no profit motivation involved; we just
want the best solution..<br>
<br>
I am looking for recommendations of a low-speed, liquid-cooled,
commercial- or industrial-grade LP generator, of at least 12kW and
preferably around 15kW, with a good reputation for long-term
reliability, and that is not designed for home standby use (with
phantom-load heaters and controls). It will be located outdoors, so
must have a weather enclosure.<br>
<br>
I occasionally am asked to answer this same question by Home Power
readers, who assume I know the answer because I wrote a primer on
generators for HP awhile back. Truth is, I don't have any good
recommendations in this size range, and I'm really hoping that some
of you experienced off-grid Wrenches who have done larger systems
can help here.<br>
<br>
Thank you,<br>
Allan<br>
