Hand Engineering</a> still makes the device that will keep the SW
memory alive. Batteries need to be changed every few years.<br>

is a follow up on the question I asked about anyone having
actual experience integrating Simpliphi batteries with a
Trace SW inverter system. </span></p>

<p class="MsoNormal"><span
style="font-size:12.0pt;font-family:"Verdana","sans-serif"">I
read the battery and integration manuals carefully and spoke
with Simpliphi tech support. The systems are absolutely
compatible but only if the inverter and charge controllers
are programmed correctly. </span></p>
<p class="MsoNormal"><span
style="font-size:12.0pt;font-family:"Verdana","sans-serif""> </span></p>
<p class="MsoNormal"><span
style="font-size:12.0pt;font-family:"Verdana","sans-serif"">Therein
is the problem: If the SW inverters lose DC power, the
programming is erased and the inverters reset to factory
defaults. These default settings are not acceptable for
safe operation of the Simpliphi batteries.</span></p>
<p class="MsoNormal"><span
style="font-size:12.0pt;font-family:"Verdana","sans-serif""> </span></p>
<p class="MsoNormal"><span
style="font-size:12.0pt;font-family:"Verdana","sans-serif"">If
the client is capable of determining when the settings have
been reset and can reprogram the inverters when needed, then
maybe the design is acceptable. In the case I am working
on, the client does not have these capabilities. It was
decided to replace the dead batteries with the same AGM
style batteries currently in use, not the Simpliphi.</span></p>
