The version i tested with the broken parallel feature was the 12/12/2022 release. I keep going back to 8/3/2022 version.
Awesome, thank you for the update and new files! Looks like that version doesn't have the AC coupling yet. I haven't had success with the AC coupling version yet. Seems to shut down my grid tie inverter and not bring it back. But it could be some compatibility issue, who knows. I'm sure I'll get to troubleshooting that at some point.There is a new firmware released for the EG4 8k inverter, the firmware will be released on the EG4 website soon for download but I have linked it below as well as the updated manual. The ZIP file contains the new firmware, software, and a change log. If you have any questions or concerns please email support@eg4electronics.com and we will be more than happy to assist you.
Thread 'EG4 8k firmware update 09.19.23'

Why does it matter what type/brand micro inverters are used with AC coupling ?I have a ac couple firmware that works but what are you using for micro inverters?
Is there a difference betweenBecause some micro inverters you have to select a grid type. There are cheat grid types to get them to ac couple
Yes. Enphase also has a Tesla profile and a Sma profileIs there a difference between
Enphase M series (grid profile IEEE 1547 default 2015)
or
Enphase IQ series (grid profile CA Rule21 201902 VV VW FW)
?
Can you select a grid profile with the Tesla or change your voltage span to be bigger as well as you frequency?It's actually a Tesla 7.6KW inverter. Odd choice but it happened to be what I had available that didn't require optimizers. This is the firmware I've got loaded right now for ac coupling: View attachment 168448
So when using Enphase micro inverters with the 8K AC coupled, set grid profile to TESLA and all is good ?Yes. Enphase also has a Tesla profile and a Sma profile
Help: If I don't want it to ever charge the batteries from the grid, what should I put in a 48V megarevo?thanks for the feedback.
No I haven't. I have net metering and I want it to feed back to the grid once my batteries are fully charged.
So I never played with those settings. But @cmack had the same issue like you: not wanting it to feed back and it did it anyway.
I have read more people with these issue's.
I really love my MR (I have 2) but the intermittent communication with MR support and no progress for a while now really disapoints me.
Since you have an EG4 branded MR, you should try leaning on EG more and try and get more/better support.
Afaik what you want: self supply mode without back feeding to the grid is *impossible* at the moment.
Mine is in self supply mode and batteries are only charged by PV.Help: If I don't want it to ever charge the batteries from the grid, what should I put in a 48V megarevo? ( set up)
I tried to find the Amensolar manual, even using archive.org but was unable to find copy.has “ToU Enable" menu (Time Of Use) with 6 Time Slots very similar to the Amensolar N3H-X8.0-US 8kw which has a very good "Advanced Settings Menu" section in their manual with good explanations. (Latest Eg4 8k v1.4.0-1 manual is similar now. Except below)
Sorry for the delay.... Covid has me laid up again. I will have to see if I kept a downloaded copy somewhere (not on my phone)I tried to find the Amensolar manual, even using archive.org but was unable to find copy.
Are you able to share a copy with me ?
I am currently utterly frustrated to get my unit to work with ToU, see my attempt starting here:
EG4 8k firmware update 09.19.23
