<p>Simpliphi has been around since 2002, so they actually are older
than their 10 year old warranty. Most other companies can't make
that claim. As far as reliability, each 3.8 kWh is independent,
so you can just shut down a bad unit and send it in for repair.
I'm building systems with 4 to 6 units usually. <br>
</p>
<p> I too have long term questions, especially about corrosion in
marine environments, and long term issues with electronics such as
capacitors drying out. I think the BMS may go out befor the
projected 8000 cycles to 100% DOD. <br>
</p>
<p> I've been a part of the solar experiment since the 80s, and
we've come a very long ways, which is amazing. For all the
questions we have, lead acid is definitely going to be come
obsolete in our life times, so the sooner we all get savvy with
newer technologies the better. <br>

<div>Discover Battery has been around since just after WWII. I
think that since each Li battery is native to the system
voltage, the way to get some redundancy is to simply have more
than one battery, most systems will anyway. Then if one fails
you can use the other ones until the failed one is replaced or
fixed. A lead battery would be less prone to catastrophic
failure, alkaline batteries even more so if you can handle the
cost and other issues, so there is something to be said for
that. I have multiple inverters and battery banks and it has
come in handy when there are failures (inverters). <br>

I seem to continue to have my foot stuck in
the past <br>
regarding off-grid. Off -grid seems to have more of an
element of a <br>
need for reliability, redundancy, klugability. Believe me
L-ion <br>
batteries and especially the "total units" like the:<br>

moz-do-not-send="true">https://simpliphipower.com/product/access-sol-ark/</a><br>
<br>
are beautiful answers to "buy it connect up the cables and
forget it", <br>
no maintenance to boot. I want one. But Yikes, many of
these companies <br>
are new, which will survive well into their warranty
period? Its a <br>
double-edge sword....if we don't transition into the L-ion
world, how <br>
will they survive?<br>
<br>
Also, if the charge controller, battery cell
(in 2 volt <br>
cell battery pack), fan or inverter fails in a more
conventional system, <br>
there's probably a go-around spare whatever in stock (or
the failed 2 <br>
volt cell can be cabled around waiting for a new cell).
Maybe all I'm <br>
asking is how field serviceable is a failed L-ion battery
or its BMS? or <br>
the total units like above? Are there failures? maybe too
soon to know.<br>
<br>
Go ahead, beat me with a stick, maybe I'll
learn something.<br>
