Also, very significantly, the SMA Sunny Boy / Sunny Island combos will
taper charge when set up correctly. <br><br>

<font size="2"> Have used both SMA and OutBack inverters
for this application. One challenge with the smaller generators is
getting a true 60 hertz, they fluctuate. The Sunny Boy can be programmed
to operate at a lower hertz range if SMA will share the "secret code
". Recently did a Outback system and the customer had a Propane
fired Briggs and Stratton gen set, two wire start, works great. I
understand why you want to use the matching SMA's.<br>

</span></dd><dd><span class="">Hi Wrenches, especially those of you who work on off-grid
projects,<br><br>
</span></dd><dd> <br><br>
</dd><dd>We have an upcoming off-grid project where we will be powering a
storage container with electronics in it. The loads are mostly 120 volt
but there is a 240 volt heat pump that might occasionally run. We’re AC
coupling the Sunny Island with a Sunny Boy PV inverter. So, we’ll be
installing a Outback PSX-240 autoformer to bump the Sunny Island’s
output from 120 to 240 volt. <br><div><div class="h5"><br>
</div></div></dd><dd> <br><br>
</dd><dd>We need to select a generator for backup. We need a two-wire electric
start (in order to be controlled by the Sunny Island) and preferably a
generator that is okay just running 120 volt loads since the Sunny
Islands input is only 120 volt. Something in the 3 kVA -7 kVA range
should be fine. <br><br>
</dd><dd> <br><br>
</dd><dd>Does anyone have experience or ideas about what kind of two-wire
start generator we might select?<br><br>
