O-Wise ones;
I have a Radian 8KW off-grid system. I am getting intermittent (one day it is there & then the next it is not) very high pitched & faint but continually rising pitch whistling & white noise on the stereo, the boom box, basically anything with a speaker. First suspect was: Pentair variable freq. & variable voltage 3P wild AC well pump & controller, but the sound happens when the pump is off or on. The controller is always on/awake. 2nd suspect: 1 HP septic lift pump, again sound happens weather on or off. Which gets me back to the inverter. I have not contacted Outback Eng. As most of the techs are younger than the Radian inverter series... Anyone else encountered this? Suggestions on getting rid of this? The House has metal roof & walls for wildfire protection & systems are extremely shielded & grounded. It is not audible while music playing at normal volumes & only heard while in between selections or extremely quiet passages. As always; Thanks for the suggestions in advance. ---------------------------------------------------------------------------- Dana Orzel NABCEP # 051112-136 Cell - 208.721.7003 Email - <mailto:d...@solarwork.com> d...@solarwork.com Great Solar Works, Idaho Inc <http://www.solarwork.biz> www.solarwork.biz ID PV Contractor - # 028765 - ID PV Electrician # 028374 "Responsible Technologies for Responsible People since 1988" Please consider the environment before printing this email.
