I haven't seen anything from them that looks like what we're after
We'd be looking for 10kW to 15 kW water cooled 1800 rpm. Propane
fired.<br>
Everyone makes models in the 30kW + range that fit the bill, but
most off grid systems don't need anything that big.<br>
Do you have a model that I should be looking at?<br>
<br>
Thanks,<br>

FYI, generally we haven't had cold start issues with propane
units, as long as the pipe is sized properly ( as mentioned in
another recent post) and the starter battery is kept fully
charged.<br>
This is based on about 20 years experience in the Rockies with
temps below 0, but not 40 below. We don't use block heaters, carb
heaters, etc.<br>
We currently have been using Generac Ecogen, but not that happy
with them. Cheap air cooled motor, way too many computer gizmos,
no on board charging (must have AC power or PV to charge the
starting battery) We even had to call customer service to get an
authorization code to set up remote start. This is off grid with
no internet or cell service; ridiculous. I hope Generac reps are
lurking here, because these are really not much better than the
crop of stand by generators.<br>
IMO no off grid generator should have a phantom load, or require
cell service to commission. What happened to the old water cooled
Kohlers?<br>

<div dir="ltr">I did some searches on the list for what
folks are doing for off-grid propane generators these
days, but all the threads I found were from 5-6 yrs ago,
so I was hoping to get some more current info.
<div><br>
</div>
<div>We're looking for about a 10kw+ propane unit (big
derate at altitude), and we run into 2 main problem
areas:</div>
<div><br>
</div>
<div>First is the warranty - either there are no units
warranteed for off-grid use, or there are only a couple
of models and the warranty is short (1 year).</div>
<div><br>
</div>
<div>Second, and perhaps larger, is all the loads that now
come with the "off-grid" units. The computer takes
some, but mostly the "cold weather kit" aka carb heater
must be installed in our climate (to actually start, but
also for warrantee), and it's set up to be on a
thermostat (read: "on all the time from Nov-April" here
in the mountains). According to the Kohler tech support
it takes a steady 50W. We have set up older units to do
battery charge only during the day, and have the carb
heater on a manual switch, but it sounds like we can't
really get at these circuits anymore since they're all
pre-configured and pre-wired in the guts of the genset
computer.</div>
<div><br>
</div>
<div>The Kohler and Onan support folks said both these
issues are due to EPA considering off-grid use as prime
power as opposed to standby, so they are held to tougher
emissions standards.</div>
<div><br>
</div>
<div>Whatever the reasons, we're wondering what people are
actually doing these days - still the standby units they
kind-of warrantee for off-grid? 12RES from Kohler and
the 13kw unit from Onan? Generac? Have folks been
going back to the smaller gas units from Honda and
running them more? And how are cold climate folks
dealing with the heating issue?</div>
<div><br>
</div>
<div>Any suggestions appreciated!</div>
