[RE-wrenches] Light Flicker Off grid

[Dave Angelini Offgrid Solar]

I have seen this with the dimmer below 50% with well/transfer pumps. I
only use the costco FEIT bulbs/CREE and no issues on XW and CSW. Avoid
dimmers or use less than 30% of dimming. I don't think the bulb being
dimmable is the issue either. It is more apparent at night when you dim an
LED. Tell them not to do laundry at night  Good Luck

 We have a
customer with a new high efficiency washer running on a Magnum 
 inverter.
When it is in wash cycle, the LED lights flicker rhythmically 
 with its
operation. We can see a corresponding distortion of the wave 
 form on an
oscilloscope, but RMS voltage is steady at 117 vac. It does 
 not cause
trouble with incandescent lighting, and the washer works fine.

 My
questions:

 1) Has anyone else seen washing machines causing trouble with
lighting 
 or other loads?

 2) Is there any line filtering available that
might cure this?

 3) Are some LED lights more prone to issues? We are
considering 
 having the customer switch from the Home Depot cheapo LEDs to
Phillips 
 or other higher end bulbs.

 4) Could it be related to the bulbs
being dimmable? Should we be using 
 non-dimmable bulbs?

 As always thanks
in advance for your invaluable input and comments.
