Thanks Dustin for keeping
us up to date on Sol-Arks feature progress.<br>
<br>
While you are upgrading your firmware: :)<br>
<br>
So an essential feature for off-grid with a generator is to be able to
program various SOC levels for generator start AND shuf-off after
charge. 90% is way too high for many sunny climes and other
configurations. Often batteries need a boost in the wee morning hours -
when they drop below the preferred recharge point but that's only
perhaps a few hours before the sun comes up - So say you want to start a
gen to charge a Lead-acid battery at 50% or an LFP batter at 20% SOC
but you only want to bring it through to the next often or possibly
sunny morning. So you set it to run from 50% to 65% (or from 20%-40%
for LFP) - knowing that the morning sun will take it the rest of the
way. 90% would waste a ton of fuel in this scenario not too mention
unwanted noise and wear and tear on the genny. Depending on the clients
use profile, the climate, and relative size of the array and battery
and gen, these figures could vary anywhere from 20% to 100%. So it's
essential us off-grid installers have that flexibility.<br>
<br>
Also I know that your TOU settings might cover this (though not in all
modes I believe) but another nice feature is to have 2 or 3 time periods
with different start and stop settings (Sunny Island does this
nicely). So if the minimum SOC is reached in the evening you might as
well bring it up to a higher SOC for gen shut down as it needs to get
through the entire night whereas if that minimum SOC start trigger is
met after 3 AM it needs to only bring it to a lower SOC as described
above.<br>
<br>
<span></span>I'm loving the Sol-Ark product so far but it is obvious the
software is a work in progress - the architecture and thought behind it
is an excellent foundation - thanks for your work and openness for
input to make it even better.<br>
<br>
Best,<br>

thank you for sharing your experiences the the Sol-Ark system. We try
very hard to have different capabilities and add new features that make
it flexible for the customer. The two-wire start is a feature however
that we want to be seamless. In the instance where the customer is
seeing the system shutdown once the generator shuts off has been
addressed and fixed with a software update. With this update we are able
to handle larger generators that tend to drift from 60hz. Please give
our support team a call so that we can update the customer accordingly.
We are also looking at adding more features including the ability
exercise the generator in the near feature.<span class="font" style="font-family:Calibri, Verdana, Arial, sans-serif, sans-serif"><span class="size" style="font-size:16px"> <br></span></span></div><br><div data-zbluepencil-ignore="true" id="Zm-_Id_-Sgn"><p style="margin: 0px" class=""><span class="font" style="font-family:Calibri, Verdana, Arial,

the Sol-Ark has a very basic and limited AGS for 2 wire compatible gen
sets. Gen start can be programmed with voltage or SOC, however gen stop
is not a function that can not be readily programmed. Instead, the
Sol-Ark is programmed to charge the battery bank to 90% of the rated Ah
capacity of the battery bank before turning off the generator. You can
ultimately adjust this gen stop parameter to be based on a specific SOC
or voltage, but I believe that doing so requires a call into tech
support. The tech I spoke with updated a setting (having to do with
a TOU parameter I believe) that was not accessible via the system
interface. AGS from Schnieder, Outback and even Magnum are less clunky,
but I am hoping that Sol-Ark will eventually come out with new
programming to remediate these minor but nevertheless, important issues</div></div><div><br clear="none"></div><div>-Chris</div></div><br clear="none"><div class="ydp84fbc9deyiv4104453845gmail_quote"><div class="ydp84fbc9deyiv4104453845yqt6477094269" id="ydp84fbc9deyiv4104453845yqt88243"><div class="ydp84fbc9deyiv4104453845gmail_attr" dir="ltr">On Wed, Nov 11,
