<div dir="ltr"><div>I've noticed this is worse with multiple bulbs in one fixture, and it is even slightly noticeable on grid power, but worse on inverter power. I first saw this with CFL's also, but not as bad as with the LED's. And this is without any motor loads going. It's not consistent either, sometimes it does it and sometimes not. Fortunately, when it's annoying we have the option of going onto grid power. If we were on inverter power all the time I'd be looking for some way to fix it also. It does not seem to matter what inverter it is either, I've tried four different brands and they all seem about the same.</div><div><br></div><div>Brad<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Sep 21, 2019 at 1:06 PM Ray <<a href="mailto:ray@solarray.com">ray@solarray.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p>No error codes, just light flickering with the washing action.
Its a Magnum MS 4448 PAE, 48 v 845 AH of HUP batteries, 2/0
cables. Happens day or night. Also the lights are not on a
dimmer, just a regular switch. It happens to the LEDs all over
the house. They are the Econolight brand from Home Depot. Feit
brand have less flicker, but are still not acceptable.</p>
<p>We're thinking the distortion of the waveform by the washer is
creating harmonic distortion that the LEDs are responding to.
Still hoping filtering or different bulbs will fix the issue. <br>

Esteemed Wrenches;<br>
<br>
We have a customer with a new high efficiency washer running
on a Magnum <br>
inverter. When it is in wash cycle, the LED lights flicker
rhythmically <br>
with its operation. We can see a corresponding distortion of
the wave <br>
form on an oscilloscope, but RMS voltage is steady at 117
vac. It does <br>
not cause trouble with incandescent lighting, and the washer
works fine.<br>
<br>
My questions:<br>
<br>
1) Has anyone else seen washing machines causing trouble with
lighting <br>
or other loads?<br>
<br>
2) Is there any line filtering available that might cure this?<br>
<br>
3) Are some LED lights more prone to issues? We are
considering <br>
having the customer switch from the Home Depot cheapo LEDs to
Phillips <br>
or other higher end bulbs.<br>
<br>
4) Could it be related to the bulbs being dimmable? Should we
be using <br>
non-dimmable bulbs?<br>
<br>
As always thanks in advance for your invaluable input and
comments.<br>
