Wrenches: 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. 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.. 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. 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. Thank you, Allan --
