[RE-wrenches] Light Flicker Off grid

[Ray]

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.

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.
