Yea I know about the humming but it gets real loud randomly sounds like it's rattling every few seconds. Something like a high power bass in a sound system the rattles the vehicle and this was with very little to no load just idling. Fans were doing there normal idol sound.I have the 6500s, but to my knowledge the 6000s are Low Frequency inverters, so you're probably hearing the transformers.
Sorry, pics added to the post.SAD ?
Oops! We ran into some problems.
The requested conversation could not be found.
Did you ever resolve this?These inverters have a loud humming vibration type sound trying to attach file but it says type of file not allowed, what kind of file extension does it have to be?
Good luck! Keep us apprised of the outcome!Hey JC how are doing. Working on getting it solved with SS.
Negative, everything had been the same had not done any changes. Friday was very sunny and it didn't charge by the time I got home its was dark so couldn't check it, yesterday it was showing about 340 volts, but like I said it was cloudy day the highest I seen yesterday was 2.4k from solar, I know Friday the highest peak I seen on solar assistant was about 9.5k but it wasn't charging on one of my inverters I could see the voltage on the display but no watts. So I reset everything then it started charging. I have been working with SS on this and they're replacing these units. I had to pay for 2 units because I am off grid and need power, then I will return for a refund. Hopefully the replacement won't have these issues that im having.Hmm.. had you changed any settings without rebooting them prior?
I am having similar problems. Did you USE for user defined on setting 5? I tried the settings you have on the chart but settings 27 and 29 don't work when USE is selected in setting 5. Can you check your settings and let me know.I have 2 EG4 6500's running in split phase and 2 EG4 lifpower4 48volt 100ah batteries. I recently hooked up 6 540watt Znshine bi-facial solar panels, 3 in series to 2P1 PV1 and 3 in series to 2P2 PV1. I had the batteries hooked up to 2P1 via the included cables and 2P1 set to EG4 and 2P2 set to User. I didn't have error 61 issues however the inverters randomly drop power for 3 - 4 seconds then comes back on. I have noticed the alarm light will flash on the inverter for a second then turn off without any indication of a fault code. I updated the firmware to the EG4 6500's last night but 2P2 dropped power 2 times after the update. I am able to see the drops using solar assistant raspberry pi under the graphs for output voltage. I was hoping it was firmware issue and it still might be... I have not updated the firmware in the battery's. Power dropping seems to happen when the battery's are fully charged in Utility mode. Based on some other threads I have read, I set both my inverters to User mode, unplugged the communication between the inverter and battery's, set bulk charge to 57V and float to 56.5V. I suspect there might be an issue with the EG4 battery setting causing some kind of hiccup. Just a wild guess at the moment. Ignore the large dips in the second screen shot, I was hooking up different loads to the inverters and had things turned off. I'm wondering if anyone has experienced similar issues and what steps they have done to remedy it. I've also made a setting cheat sheet to make checking the settings a little easier and thought I would post a picture. I have it in excel and am happy to share with anyone or take tips on anything I should change.

I had a similar issue, my inverters were replaced and the new unit did the same thing just not as often. SS had me change my settings and quit using EG4 in setting 5. It been about a month and things seem much better. The following is the settings I was asked to use,I am having similar problems. Did you USE for user defined on setting 5?

Thank you! I really appreciate it!I had a similar issue, my inverters were replaced and the new unit did the same thing just not as often. SS had me change my settings and quit using EG4 in setting 5. It been about a month and things seem much better. The following is the settings I was asked to use,
User Settings: Change setting 5 first, if settings are still in percentage mode turn off inverter and then back on.
Setting 1 SBU
Setting 2 80a
Setting 5 to USE
Setting 12 to 48V
Setting 13 to 57V
Setting 26 to 57V
Setting 27 to 56V
Setting 29 to 46V
Thank you!
Just to make sure that the firmware update uploaded the 2nd CPU display screen it should read 61.06
Note, I use solar assistant for controlling my battery charge, the settings from SS seem to discharge to low
