Allan: DISCLAIMER: I have no business or financial relationship with any Generac dealer. I have owned two Generac EcoGens in the past 10 years and am pleased with their performance. The EgoGen is configurable using an option setting to use either LP or NG fuel. It is warranteed for the off-grid environment, with a 500 hour recommended interval for routine maintenance. Even though I live in an urban area, I setup my PV system in the grid-tie battery backup configuration. I have always used LP for fuel instead of natural gas because of some issues we've had with natural gas reliability here in north Texas under extreme winter weather conditions (last one here was in mid-February). I use my EcoGen only as a battery charger in a grid-down situation, it does not serve house loads directly. I'll admit that most of the hours on my generator are the bi-weekly exercise runs! I started with the 6kW 240V AC EcoGen as a field trial participant in Generac's beta testing of the EcoGen in an off-grid environment in 2010. Later I upgraded to the 15kW kW 240V AC model. I very pleased with this model too. So, consider Generac as an option too.

Indeed, I called a longtime regional independent generator dealer about this before posting here. I was surprised that he has Kohler 12s and 14s in stock and available. I’ll go that route if I don’t hear better from our fellow Wrenches.

We see so many generators bought online with no way to get service because there are no local and qualified service technicians to service that brand. If you buy from a local technician, or at least ask for their advise, it may allow you to get service in the future (maybe). We have had good success with Kohler 14 RESA or RCA machines, they do have off grid warranties, but good luck getting them now. Let us know what you decide.

I just placed my first order for one. 10KW LPG 1800RPM liquid cooled, built to run 24/7. They even make a DC (battery direct) generator. You can purchase through a master dealer in the Reno Nevada area, Freds Mountain Electric: https://fredsmountain.com/ https://wildcatpowergen.com/ On Fri, Oct 15, 2021 at 3:37 PM Sindelar Solar <al...@sindelarsolar.com> wrote: Wrenches, Generators have become a moving target, especially for off grid applications. Most are set up for grid backup, and I'm assuming that many may simply be unavailable, given that half of most everything else is on back-order with no expected delivery date... I'm seldom asked to recommend a generator these days, but I am today, so I'm requesting recommendations from other off grid-savvy Wrenches, please. I'm working with an older (2014?) existing dual Outback VFX3524 system which will be upgraded to dual VFXR-3648s to work with a 16kW Blue Ion LiFP battery bank; 4kW array with upgrade infrastructure in place to later add 2kW more if needed. Once the upgrade is done I expect relatively little generator runtime. The customer would prefer LP fuel and 2-wire start (for remote control). Pretty much any well-regarded model in the 8-14 kW @240 VAC rating range could work. Thank you for your suggestions!
