<p class="MsoNormal">Hey Glenn,</p>
<p class="MsoNormal">I just started running a LIFEPO4 battery with a Sunny Island, no closed loop communication but with settings pretty much what Fortress</p>
<p class="MsoNormal">has on their Sunny Island sheet. Settings are lower than what some LIFE’s specify, to avoid a voltage jump / high voltage error at the end of the charge cycle from what I’ve seen.</p>

<p class="MsoNormal">Hello all – best wishes for the new year.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a client with an aging (dead) AGM (16x Concorde PVX-3050T) battery bank with two Sunny Island 5048 inverters (and a few SB in the mix too) in a GTWB configuration.<o:p></o:p></p>
<p class="MsoNormal">Has anyone successfully replaced an AGM battery bank with a LiFe ESS solution with closed loop comms and Sunny Islands?<o:p></o:p></p>
<p class="MsoNormal">Something like a Fortress eVault max?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Or should I simply replace the existing AGM’s with the same model batteries and let it go another 10 years?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks for the feedback!<o:p></o:p></p>
