<p>The Generac EcoGen is dual-fuel capable (NG or LP), comes in 6kW
and 15kW versions, is 2-wire start, can be field-configured for
either 120V or 240V. It's not "portable" as it does not have
wheels. It's transportable though based on its footprint and
weight. Also, it was specifically designed and warranteed for
off-grid applications.</p>

the whole 120V sunny island setup is a disaster. Why not
install a DC coupled 8KW Outback Radian and solve all your
problems. USe any 240V generator, although finding a 2

all mounted on the container. I would never design
anything to use gasoline, it's too dangerous.<o:p></o:p></span></p>

lang="EN-US">Greetings August,<br>
<br>
Great thoughts and comments from Brian! I would also
suggest speaking<br>
with the generator manufacturers' tech/engineering
folks regarding the<br>
120VAC configuration and to confirm 2-wire start set
up once you have<br>
a brand and model or two in mind. Generator parts and
service<br>
availability in the region of the project may also
drive brand<br>
selection. If you need to maximize the inverter's
battery charging<br>
capabilities (depending on battery system charging
requirements) you<br>
may end up needing to look at generators in the 7.5 kW
to 8.0 kW<br>
capacity range to allow for headroom in generator
output loading.<br>
<br>
Also; I am curious how you arrived at an AC coupled
design for this<br>
project. I do not know any of the details or specific
projects goals<br>
you are working with, but I would potentially consider
a DC coupled<br>
system design... DC/DC charge controller(s) would
keep the battery<br>
system charged (and any DC loads operable) even if the
Sunny Island<br>
and/or Sunny Boy(s) have a failure or is taken
offline. If most of<br>
the AC loads are 120VAC I would consider keeping the
inverter AC<br>
output circuit 120VAC and install a dedicated
transformer solely for<br>
the 240VAC load.... Or perhaps consider a 120/240VAC
inverter model.<br>
Depending on the overall situation a DC coupled system
could be more<br>
resilient. The dedicated transformer for the 240VAC
load could also<br>
potentially help make the system more robust. Also; I
have spoken<br>
with a number of folks who have told me they wish the
Sunny Island had<br>
more/better features for generator integration. I'd
like to hear more<br>
from those who have plenty of experience designing and
installing<br>
systems with Sunny Islands and generators to learn
what the current<br>
thoughts and issues are.<br>
<br>
I hope some of these thoughts may be helpful.<br>
<br>
Best regards,<br>
<br>

[RE-wrenches] Generator choice for Sunny Island<br>

Hi Wrenches, especially those of you who work on
off-grid projects,<br>
<br>
We have an upcoming off-grid project where we will be
powering a storage<br>
container with electronics in it. The loads are mostly
120 volt but there<br>
is a 240 volt heat pump that might occasionally run.
We’re AC coupling the<br>
Sunny Island with a Sunny Boy PV inverter. So, we’ll
be installing a<br>
Outback PSX-240 autoformer to bump the Sunny Island’s
output from 120 to<br>
240 volt.<br>
<br>
We need to select a generator for backup. We need a
two-wire electric start<br>
(in order to be controlled by the Sunny Island) and
preferably a generator<br>
that is okay just running 120 volt loads since the
Sunny Islands input is<br>
only 120 volt. Something in the 3 kVA -7 kVA range
should be fine.<br>
<br>
Does anyone have experience or ideas about what kind
of two-wire start<br>
generator we might select?<br>
<br>
Thanks,<br>
<br>
August<br>
<br>
