EG4 6000XP lights flickering

On the inverter with the issue, triple check that you have L1 matching with L1 on the others and L2 matching L2. Also make sure the neutral wire coming from the upper section of the inverter is connected and tight on the N bar.
I will double check it, like I said though I had no issues for the first ~2 months, this issue just started but I will check to be sure all the connections are good.
 
That was 2 months ago. It could have worked loose. Or maybe wasn't actually tightened down (I found out our toilet was finger tight, somehow hadn't leaked yet but had shifted since the previous guy installed it 5 years ago).
 
Okay been playing around, it is flickering when on battery, was not when grid was kicked in. I was pretty sure it would do it all the time previously, maybe I was mistaken, I will have to do more tests to find out for sure.
 
I went through all my panels and sub panels on the property and found 5 circuits that had the ground on the neutral bar (was in a sub panel in the house), so I moved them to the ground bar, not sure if that would cause these issues or not (it did not up until this point if it could cause issues). I have not noticed any flickering today but I have not been in areas of the house or pole barn that have a lot of led lighting or lighting in general that have been where the issue was most obvious.

I had a similar issue after running on the generator for a few hours; weird flicker from several of the LED lights.

Restarted the two 6000XPs but same flicker.
Checked all AC feed wires but could find nothing loose.

Spent 10 minutes checking all the settings... found output voltage had strangely been reset to 100v. WTF!!!

Changed the setting back to120v .. and inverters restarted on saving setting. Presto .. no more flickering lights.

Worth checking anyway.

Just checked, they are all set to 120/240v, thanks for the suggestion though.
 
You must have an appliance with a very low power factor.
Example, an inverter air conditioner or refrigerator. When either one operates at max, you will not see any flickering because the motor is operating at high power factor nearing 1. However the moment the motor slows down, the power factor drops to below 0.6 or 0.5, that when all the LED starts to flicker.
 
Okay so it is definitely happening when on battery, not when the inverter switches to grid power.
 
Speaking of power factor, my HVAC blower motor (in heat mode aka lower speed) had a terrible power factor. Ended up changing the run capacitor with one that's rated correctly and that fixed the low PF
 
nope :) Still no flickering yet since turning off the one inverter, will monitor throughout the night etc.
How's everything going? any flickering again? Maybe it was just that one unit acting up. If you've got the fluke 375 FC meter you can log the voltage data and save it so you can know what the voltage was doing during the flicker... pretty expensive though. I'm really tempted to get one.
 
Just had my first grid power failure with my new solar backup system. 6000xp and 2 eg4 lls 48v 100 amp hour batteries. Purchased signature solar and installed in December 2024. Everything seemed to work ok except all led's on dimmers flickered like a strobe light, flashing 2 or 3 times per second. Back feeding main panel through circuit breaker interlock. Bonded neutral in main panel, no bonded neutral on 6000xp setting. Bulbs flicker slightly on grid power but adjusting the dimmer seems to solve. Adjusting the dimmer while getting power through the 6000xp does nothing. I will be contacting signature solar to see if there is anything that can be done.

If they are doing this on grid then you are absolutely going to have problems when powering from the inverter. Sorry not what you want to hear but this will absolutely be the case.

It seems to be when on battery power it flickers and not when the grid has kicked in. All 3 inverters are back on and so far only seems to be happening when on battery.

It sounds like the parallel setup isn't set up properly. Did you set the switches and CAN cables and settings according to the manual?
 
I recently had this happen to my two 6000 xp's in parallel... But only when I restarted them. They burned up a bunch of stuff in my house. ryobe battery charger. bunch of LED lights, the transformer in my furnace and my furnace control board. Have you noticed any LED lights or other equipment going bad? I'd consider switching back to grid to troubleshoot. I posted on this already.
I called Signature solar....The tech said he usually sees light dimming when you have issues with the Ground neutral bond(No GN bond, Multiple bonds, etc). I'm still troubleshooting my GN bonding in my house... but I think it could have also been caused by the inverters not working properly in parallel mode.
Check if the neutral goes through a relay in the inverter. If the L1, L2, an N relay are signaled to switch at the same time, you can get unbalanced voltages if the neutral relay is the slowest to switch. The fix is to run a neutral jumper wire from the grid port to the load port. Why would they put a relay on the neutral? I don't know.
 
They are dimmers on three way switches. There is a neutral in the circuit returning power after led's.
But the dimmers themselves don’t have a connection to neutral? They need a power supply to run their circuitry, and while they can play games with ground or the load wires, those don’t always work well, especially non-linear loads like LED bulbs. One thing you might try is to temporarily put an incandescent bulb or two in the circuit to change the load.

Not all LED bulbs are dimmable, and not all dimmers can handle LED bulbs, and not all dimmers that (say they) can handle LEDs are compatible with LED bulbs that (say they) are dimmable, especially when the dimmers don’t have a neutral connection.

Interestingly enough, my Leviton dimmers I just installed in our kitchen for our new fixtures (which all use dimmable LED bulbs) don't have neutral (I thought that odd) but they work great, except for for one that is slightly odd perhaps as all 3 bulbs on that dimmer occasionally do a very quick blink. Of course, it could be an oddity with those particular bulbs. I have Ecosmarts in that string of pendants over the kitchen island, Sylvanias in the string of can lights, and Philips in the last fixture over the table. Seeing that all Ecosmarts blink at exactly the same time I suspect more from the source (dimmer) than a bulb issue specifically.
 
Every dimmer I ever wired had 4 connections and i've wire hundreds:
2 travellers
1 connection for either power or neutral depending on the location of the switch in the circuit.
1 ground
no dedicated neutral

The 6000xp has a software setting to bond the neutral to ground. I left it unbonded as you would a generator used for home backup. Don't want to have 2 paths to ground. Maybe that's my problem.

Only one or two lights flicker on grid which I can attribute to bad bulbs or dimmers or bulb/dimmer combinations. On the 6000xp all my led bulbs on dimmers flicker like a disco bar and i never enjoyed that. Ok I can remember a couple of nights in the 70's that I enjoyed it!:)
