[RE-wrenches] Radian Buzzing

[drake.chamberlin at redwoodalliance.org]

Hello Wrenches,

What does it mean when a Radian spontaneously emits a fairly loud buzz 
for the better part of a minute and then stops? The loads were small, 
just a few amps.

This is an off grid system with no AC input. The generator is not 
connected. There are microinverters, AC coupled to the system, but the 
light level was very low at the time.

Outback has not responded to this question after several days and 
several messages, including the submission of their online form to start 
a case.

Thank you,

Drake
