We've seen as high as 50% failure rates in full time off grid use as backup. Charging batteries for hours is a very hard load and does not compare to biweekly exercise mode. The failures have been fairly catastrophic, resulting in blown motors. <o:p></o:p></p><p>The other issue with these types of pad mounted generators, as Allan just mentioned, is that they need to be pulled and taken into the shop for major repairs. This can quickly add another $500 to $1000 to the cost, to have a tech with a crane pull it, truck it in, and then reinstall it later. I'm actually just recommending a good quality portable generator for this reason in many cases. At least the customer can take it in themselves if there's a problem.<o:p></o:p></p><p>The alternative is to get into the bigger (>20 kW) units with water cooled motors and 1800 RPM operation. I was surprised when I compared fuel consumption, the big units can actually use less fuel than an Ecogen when charging with dual inverters. The wildcat is interesting, but I'm not ready to recommend a manufacturer I've not heard of before.<o:p></o:p></p><p>Another option I have not tried in cold weather, is diesels. I have clients in warmer places with Kubotas that have offered excellent service. I have clients in Alaska that love their diesels, but I'm not sure what they've done to cold proof them.<o:p></o:p></p><p>Ray Walters<o:p></o:p></p><p>Remote Solar<o:p></o:p></p><div><p class=MsoNormal>On 10/19/2021 1:13 PM, Sindelar Solar wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal style='margin-bottom:12.0pt'>Gary,<br>Interesting that you bring up Generac in response to my request. The customer for whom I made this request for recommendations has a dead Generac EcoGen 15kW at her property now. I don't know what's wrong with it; it had failed before she bought the property. But she had it checked out and was turned down for a service call at her home, told instead that it would have to come into the shop and that basically the cost of repairs was more than replacement cost. So another EcoGen isn't likely at this point. <br><br>Even on Generac's website, there are a surprising number of 'one-star' reviews for the EcoGen 15 (the EcoGen 6 is discontinued). The one at my own home, an early EcoGen 6 that Generac gave me around 2010 in return for evaluation and review, had a throttle solenoid fail with relatively few hours on it.
