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.

It will be located outdoors, so must have a weather enclosure.

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.
