Seem to recall something similar with early FX inverters.. Don\u2019t recall the particulars but it might have had something to do with loosing their mind before shutting down.. maybe a shorted output.<br>

<p class="MsoNormal">I have a client who has a couple of the Radian 8048's and has an error code of "AC Backfeed Error GS-1". Looking at the manual it states that "Usually indicates another AC power source (out of phase with the inverter) was connected to the
unit\u2019s AC output. Can also occur if an out-of-phase AC source is connected to the inverter\u2019s AC input."</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">However when this happened the generator wasn't running and it's an off grid system. Is there a way that the master is looking to the slave as another power source? The system had been running fine this week, auto running the generator
early morning and shutting down on its own. </p>

<p class="MsoNormal"> </p>

<p class="MsoNormal">Anyone seen something like this before? Thanks,</p>
