I just checked, and that is what is installed.

Hi Drake,
Do you have the AC coupling firmware in the Radian? It should be at least Required Firmware 001.006.070
This is a good place to start:
We do take it off line when the pulsing is bad.

If the AC was high and loads low, it was fine.
If the ac low and loads high no issue

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.

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.
In another location, with a Sunny Boy AC coupled with a pair of stacked
VFX3524 inverters, there is some pulsing in low light conditions.

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
Hello Wrenches,
An AC coupled arrangement, with an 8 kW Radian and 8 Enphase
microinverters, pulses lighting at low levels of array illumination.
This is generally not too much of a problem.
Under certain levels of solar isolation, the pulsing becomes extreme and
causes the motors in the
