I would be very interested to know with all this Overloaded/Stressed electric grids in Texas and elsewhere and push for more PEVs if any of these vendors /manufacturers, etc are putting any pressure on legislation, lobbying, etc to ease some of these over reaching power company...
Just wanted to grab a few posts (6-10) and work on doing a roll-up in one spot of what's gone into getting a working EG4 8Kw / MR R8KLNA inverter setup for my dad's house.
I will add that this has been a bit of a learning curve for us even though dad (John4178) has some residential...

I got pulled in after my 71 yr old dad tried to get the 1st unit up and running. He spent a good bit of their 401k on this trying to get some piece of mind against grid failures, etc. (Tried to get him to go with the SolArk 15k , but it was out of their budget... & wasn't...

Went back and checked dad's panel layout ... You called it... significant shading until about 1-2pm, & didn't realize panels/Rack was that far back in the property... Will have to figure something out,... Maybe see if neighbor...

Looks like you're on v23 (I just loaded v22 to get advanced menus working. (Supposedly there's an issue with Generator /AC Coupling feature on v22)
What were the issues you were having and what was supposed to be fixed with v23?
@fromport seems to be keeping track of them here.
Just popped in for a random check...
Running the eg4-8k at parents house... a year now and seem good to go... (Glad to see @fromport has his sorted out)

Me too. It would help us have some better understanding of the longevity/reliability of the unit if more people that are using it posted back as well.
I hope that EG4 /Signature Solar / MegaRevo are still working on FW improvements, etc... (v22 is working well for our usage scenario)

Previous screenshots were taken at same time in the app.
Doesn't match most of the time. I just assume the inverter is limiting the available PV input for some reason that I don't understand?
Here's it is again just now... Where's the other 500w of Pv going?
@Markus_SignatureSolar ... Do...

Planning to try this same fw out on dad's Eg4 8K setup, since we can't get the grid to charge the EG4 battery bank at night in Self Consume mode (Battery priority will do it but, we have/need Zero Export enabled).
Spoke with SigSolar Support (Brent & Markus) about some of our issues and found...
Updated bottom of previous post with links.
Basically what you're doing sounds like what we need to do. Just not sure how to set that up.
Currently run off solar during day in Self Consume (~20-24 Kwh pV generated per day, with ~33 Kwh usage, & 6x LifePower4 batteries) .... So battery ends up...
Similar....
EG4 8KLNA Inverter (fw v22) = id 1
EG4 LP4 batteries:
batt 1 = id 0 (connected to the inverter)
batt 2 = id 2
batt 3 = id 3
batt 4 = id 4
batt 5 = id 5
batt 6 = id 6
Not sure what version the batteries actually are ... or the current fw on them at the moment until I can get back...
That would be great to see your config setup written out or a video of your setup/configuration.
Came across one of your videos the other day... Just can't find a lot of actual grid tie setups/commission videos for this 8k or any layman's explanation of most of the settings, monitoring screen...
It's mainly the 2nd one (battery runs down to 20% SoC and barely charges if at all from Grid & Grid runs loads at night, but also power is cheaper here at night I believe. just found this...
