<p>P.S. The Radian is set to phase shift, and it reliably shuts off micro inverters at set point voltages. The issues occur at lower battery voltage, below the set points for the phase shift. </p>

<p>The inverter is set to ON not to SEARCH. If the Enphase circuit is switched off, the pulsing stops immediately. This system has both AC and DC coupling.</p>
<p>In another location, with a Sunny Boy AC coupled with a pair of stacked VFX3524 inverters, there is some pulsing in low light conditions. The Radian and Enphase combo is much more noticeable.</p>

<div dir="auto">I would think that in time there might be damage. Check to make sure the inverter is not on search but I stead "ON", next if you turn off the enphase the the outback perform normally. Check the inverter frequency to see your frequency is shifting have one that has both AC & DC Coupling and no issues.</div>
