The version i tested with the broken parallel feature was the 12/12/2022 release. I keep going back to 8/3/2022 version.

For anyone that wants to try it out, this is the ac coupling firmware. I haven't gotten it to work yet, no voltage on the Generator terminals when I have that setup as the ac coupling input. Unfortunately there is nothing documented for ac coupling on the load1 output, I know the sol ark can do this it's just recommended to use the generator input so the inverter can track how much is being brought in via ac coupling another inverter.

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.

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.

I have a ac couple firmware that works but what are you using for micro inverters?

Why does it matter what type/brand micro inverters are used with AC coupling ?
Just curious...

Because some micro inverters you have to select a grid type. There are cheat grid types to get them to ac couple

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:

Is 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)
?

Yes. Enphase also has a Tesla profile and a Sma profile

Can you select a grid profile with the Tesla or change your voltage span to be bigger as well as you frequency?

So when using Enphase micro inverters with the 8K AC coupled, set grid profile to TESLA and all is good ?

Sma is the best one to use so far
Help: If I don't want it to ever charge the batteries from the grid, what should I put in a 48V megarevo?

Mine is in self supply mode and batteries are only charged by PV.

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:

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.

Here's the link to the Amensolar N3H-X8.0-US

Same for the user manual
*WEIRD*
I just used a command line program to fetch it:

IPV4 (which links uses) works fine.
Sorry to have bothered you but I have it now!
