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.

A few questions, do you see a code, what size is the inverter,
batteries, cables, day or night operation.

Greetings Esteemed Wrenches;
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.
