With some external controls maybe I can actually get my inverter to operate the way it should have out of the box ;).

Ok I'm a bit stupid. But I did find it. I started watching a video on how discovery worked and it's from the sender (Solar assistant) end. Went back to those settings and I had discovery turned off. Lol I'm sure I'll be back for other questions. With any luck I'll answer them myself!

Trying to get data into Home assistant from Solar Assistant so I can do some automation. However I am just adventurous enough to get stuck. I've spent the day reading and poking and now hoping someone can point me in the right direction! I have MQTT setup and data is flowing into home...

Nope, never did find the right connector.

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:

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...

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...

My first guess would be those two data points were gathered at slightly different times on a partly cloudy day. Do you find its consistently inconsistent?

Yep that’s exactly how I had it setup. I would zero out my meter 5am to 8pm during high cost rates.

I talked to them about this. When I originally installed a single inverter I installed my CT’s before the main panel to offset up to 8kw of the whole house. Worked as expected. Of course the CT’s are 90a so undersized for the effort. They said one could put them like this for a dual inverter...

Yes indeed, I am technical but getting into modbus isn't something i've ever done so I'm thankful for people like you that are sharing knowledge! I was told I'd have to either buy 100 units or pay $1400 to get Solarman access where I could change settings to the inverters remotely. I don't know...

Yeah that doesn’t look good. What if you add load output and soc to that graph? The solarman data has been very reliable for me even if it is clunky.

Are All the panels south facing? You should be getting more than 50% output. My south facing arrays in triple digit heat will still do 75%.

Awesome. Maybe you can get at least one mode working and then play with it from there. I know many people will likely want to just set the inverters to self consumption and let them run the battery down to dead overnight as needed. I ran my pair of inverters like that for about a week and it...

Yeah and it's different with every firmware revision it seems. So with what like 8 versions fromport has documented we probably have 8 different versions of the users manual and no real experience behind any of it! I'm hopeful the version I'm on is going to work OK and I can create some...

Here's what my graph looks like from today. Didn't get the settings right until mid morning. You can see where it went from pulling from the grid in orange to flat lining. Then as soon as the battery was at 100% it started feeing to the grid (orange going above the line). The only thing wrong is...

Yep sounds like the same scenario. They are tweaking my settings now, he said they are talking to R&D so I think something in my run today didn't match with what he thought the inverter would do. If I don't give an update by tomorrow feel free to ping me. I can take a video of all the settings...

What scenario exactly are you looking to achieve? For me I have free nights so I'm charging nice and slow 8pm to 5am then running self consumption 5am to 8pm or until the battery is dead.

Pleaded to MR last night and they tried to update my inverters. I was told before hand but neither of us considered that the inverters were powering the modem. Anyway after I took my laptop in and upgraded them both we got TOU settings put in. Sure does add a lot more flexibility. I can now set...

Well then. Looks like I'm behind a bit on firmware. I don't want to update it tonight since I won't be here tomorrow but I'll likely try the newest on Thursday morning to see how it operates.

Where are you seeing those advanced settings? I feel like I might be missing that menu. Or I'm just dumb and don't see it :).

I'm trying to get Megarevo to address this. However I haven't been able to test it as I don't have enough solar right now to get my battery full during the day! I presume you are running in self consumption mode? Do you have one inverter or multiple?

Yep I had a sales person start telling me about how they were coming out with an updated model with a color screen. I couldn't care less! Just need it to operate as designed. Ha ha. Trying to convince them I can help them debug it and make it a great product. I'm hopeful as there was mention of...

I did manage to bug the MR folks enough they adjusted my voltages (One inverter was also about 2v higher than the other, just another level of ugh). But haven't gone back to closed loop to see how well it works. I'm suspicious if it will actually work as intended. And getting info out of MR is...

fromport, I need to circle back around to messing with my Seplos BMS comms to my Megarevo. Last I played with it it seemed like the Seplos would advertise the "max voltage" to the inverter. This is the same voltage that the BMS would go into protect mode at. Inverter would interpret this as hey...

When talking with Megarevo over Whatsapp they have access to many more settings over the wifi stick than I have access to. I've asked for the configuration access and get crickets. I suspect EG4 has this access as well. But so far I don't understand why the consumer or at the very least an...

I hate to be that guy, but I’m looking for an rs485 proxy and can’t find it. I’d be willing to spend a few bucks and see if it works. Even if solar assistant wasn’t able to modify, just read. Does someone have a link to one they think might work? A switch to go between the two if of course an...

That's a bummer but I suspected something like that would be the case. I appreciate your offer, I'm not ambitious enough to make it work at this point though with the proxy I think.

I like solar-assistant for my pair of Megarevo inverters, however I keep having to change back to the original monitoring sticks for Megarevo to login and mess with stuff. Is it possible to run a splitter and have both running at the same time? Would it be as simple as just connecting all the...

I've been back and forth with the folks at Megarevo trying to get my system dialed in. This evening they "calibrated" the battery voltage reading between my two inverters. One was reading about a volt below the bms and one was reading over a volt high. Then I was getting yelled at because I had...

Very interesting, thank you for trying that. Here's what I saw today MPPT1 on each inverter is a 7 panel string of 395w panels facing the same direction: MPPT4 on the first inverter is the third string of 7 panels on that same roof plane: Earlier in the day we had some full sun and all three...

Looks like the low input on overcast conditions is back unfortunately. For inputs 3 and 4.

I've been searching through Digikey and other places and can't seem to find something I could use for running a solar-assistant box into this inverter. This one looks really close but the measurements aren't quite right...

Calibrating battery voltage. I have two r8klna's and one shows 2v higher for battery voltage than the other. Verified with a multimeter. Both inverters are wrong. Seems to be playing havoc with closed loop battery communication since the bms hits high voltage cell protect before the inverter...

I overlooked a setting in the paralleling menu of the master inverter. You can set the overall max charge and discharge rates. I suspect this will solve my current issue. Thanks to the Megarevo folk for pointing it out.
