<p>It seems that battery based inverters are not nearly as reliable as they once were. I understand that the Samlex inverters are pretty bulletproof. They are coming out with a 120/240V split phase to work with a 48V battery bank. I don't know that these are grid interactive, or if they can be stacked.</p>
<p>We need a manufacturer to produce something equivalent to the FX series inverters, or the earlier Radians. </p>
<p>What is the best choice for a grid interactive, battery based inverter? I tend to lean toward Schneider.</p>

<div>We too have been plagued by this issue, that has been extremely frustrating for us and our clients. </div>
<div> </div>
<div>The newest 1.4.6 firmware is supposed to fix this issue. We have updated our systems with this and so far so good. However because of the sometimes long delays between the faults we can't be certain. </div>
<div> </div>
<div>Prior to this most common fix was replacing the mate. </div>
<div> </div>
<div>Also on FP2 we had a couple factory units have the hub jumpers set for the wrong stacking. I believe they were set for parallel operations versus series. Strange it would work fine with the jumpers either way for a long time. But it's worth a check. </div>

<div style="font-family: Calibri,Helvetica,sans-serif; font-size: 12pt; color: #000000;">We have had chronic inverter firmware mismatch issues with FLEXpower TWO FXR series on many systems.</div>
<div style="font-family: Calibri,Helvetica,sans-serif; font-size: 12pt; color: #000000;">We've updated the firmware and replaced mates, yet the system failures continue.</div>
<div style="font-family: Calibri,Helvetica,sans-serif; font-size: 12pt; color: #000000;"> </div>
<div style="font-family: Calibri,Helvetica,sans-serif; font-size: 12pt; color: #000000;">The systems will work flawlessly for months and then randomly show error and the firmware mismatch. Occasionally the system will discover (on its own) that the firmware is the same and turn back on. But usually, the "solution" is to unplug the mate and plug it back in and like magic...everything works again anywhere from 3 months to a year.</div>
<div style="font-family: Calibri,Helvetica,sans-serif; font-size: 12pt; color: #000000;"> </div>
<div style="font-family: Calibri,Helvetica,sans-serif; font-size: 12pt; color: #000000;">This is disappointing and frustrating to the system owners as well as costly and time consuming for us.</div>

<div style="font-family: Calibri,Helvetica,sans-serif; font-size: 12pt; color: #000000;"><strong>Any guidance in resolving this issue would be greatly appreciated.</strong><strong><br /></strong></div>
