They certainly have had their hiccups, and there is a fair amount of complexity to the programming depending on what you are trying to do, but they are solid both electrically and programmatically from my experience. I also have so far enjoyed using Sol-Ark from my limited experience, although I have yet to use it in an off-grid environment.</div><div class="gmail_default" style="font-family:verdana,sans-serif">Howie<br clear="all"></div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><span><span><font color="#888888"><span style="color:rgb(120,63,4)"><b>Howie Michaelson<br></b></span><span style="color:rgb(0,0,255)"></span></font></span></span><span><span><span><span><font color="#888888"><span style="color:rgb(106,168,79)"><b>Sun Catcher</b></span><br><span style="color:rgb(68,68,68)"><span style="background-color:rgb(255,255,255)"><font size="2">

<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>
