[RE-wrenches] Pulsing with AC coupling

[drake.chamberlin at redwoodalliance.org]

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 refrigerator and air-conditioner to pulse, 
sometimes causing very audible vibrations.

Will this harm the appliances? Is there anything that can be done to 
moderate or stop the pulsing?

Thank you,

Drake
