Hello,
I recorded video showing the EG4 6500EX inverter causing INSANE amount of flickering lights to the refrigerator bulb & extension cord light indicator.
My brother in law has exact same setup as i do, but with EG4 3000w yellow smaller inverter version and does NOT have any issues with his inverter flickering.
I uploaded to YouTube
I had the eg4 6000ex and it did the same thing. Had the flickering and constant clicking on my computer UPS. The refrigerator’s main board was replaced 3 times during the time I used the inverter.
