I was reading another thread possibly in a different forum where the person had an Outback and had flickering as well. I truly hope this does not affect you. I scoured all articles relating to this so I can't remember the exact forum.
no no, may your lights be bright and flicker free!Hey don't go jinxing me ok?
That waveform looks great. But if there is no load, then we can't tell if it would be a problem with loads or not.
So that is with PV only out to the lighting circuit. DC and AC have been completely removed. The wave is much improved over all other testing scenarios but the lights still flicker in correspondence to the abnormalities. The constant on LED's did flicker less, enough where I would just ignore it. The dimmable ones.. still terrible. On mains the low threshold was a steady 10v out to the lights, on inverter it was an oscillating 5.6-12.8v hence the flickering. The dimmers just can't chop the trailing end of the wave properly with the inconsistencies.
Please elaborate! You had flickering issues as well? I am relieved to hear this is not just me! Seemed like I was the only one on earth to have an issue with these units. Funny you said that about the fans. The left most fan cooling the mppt sounds like the bearings are gone and I was just going to replace it if I was stuck with it. The full list of things wrong are: left most fan bad bearing, PV2 input was intermittently not working and lighting flicker along with the unstable sine wave. I removed the cover and found a bad crimp at the MC4 and then traced it back and also found the ring terminal screw loose. Tightened and it's been OK since.
All the LEDs are high end dimmer bulbs and the dimmers are for LED's. They are flicker free on grid, generator, ecoflow delta pro and ego nexus inverters. This is the only time we ever had flickering issues in the house. The house was built in 2006 so the electrical is in good shape.
Yes, similar to what I understand with your situation, I had constant LED lamp flickering, but only when the inverter was active (not in line mode or bypass mode). It was constant, rapid flickering, and awful. I ended up buying a variety of bulbs and noticed that the Philips Hue bulbs are immune.
This is also true. Only the cheap LED bulbs with small form factors flickered for me. The Philips Hue (smart/bluetooth) lamp is also immune, probably because it has its own voltage-smoothing built in?
I think because the cheap ones use tiny capacitors. The drivers in some of the expensive bulbs I have cost twice as much as entire cheap bulbs.
Well in my case I have flickering in $280 Philip architectural fixtures and hue bulbs. The architectural fixtures have multiple caps on the drivers, If I remember right 8. They should 100% not flicker lol
100% agree. They should be isolated. All motors can induce noise, every engineer should account for this.
Speaking of noise and accounting for it, the power supply for the LEDs on the front panel make an audible noise. When I turned off the front panel LEDs the audible noise went away. Both of these issues make me question the quality of the engineering in this unit.
