Smoken Peace Pipe, makes one Strong and brave. I'll see you over the mountain I'll see you there. . .
Sid, how about the bluetooth,? can't sean activate those and use it to do the phase shift? I remeber you said it had it, if sean tie the two bluetooth together then when he ships them they are already paird up.

Like have them activated, then code it to auto connect to them but not broadcast open ID, only the dev mode would show it and once they auto pair up they can shar the data they need such as the phase timing and watss or what ever you want as well as it could be setup to let each one know if its a slave or master or slave 2 and so forth what ever. I think you can make bluetooth invisble, not sure. I know wifi you can, I figured bluetooth might work the same way.

Grr... <a contenteditable="false" data-ipshover="" data-ipshover-target="/profile/3-the-blind-wolf/?do=hovercard" data-mentionid="3" href="/profile/3-the-blind-wolf/" rel="">@The Blind Wolfthere's real work involved in the Genetry Solar project, I've designed it literally from the ground up. Maybe an occasional boost here and there with ideas--but nowhere in the real world does it work like "throw predesigned code into the box, shake it 5 times, and *poof* everything works perfectly."
I can spend all day--like today--just trying to get one little thing working. Currently trying to figure out why the frequency control registers are mysteriously reading 1/2 what they should (on the WiFi board) despite the inverter functioning fine, indicating a problem somewhere else...haven't found out where.
Yes, the ESP32 supports Bluetooth. But implementing the functionality of Bluetooth would require another month+ of programming to figure out, adding another ginormous stack hogging up memory/space in the WiFi board--and at the end of the day, the info still has to pass thru the WiFi board to the CPU--further adding delays due to data packet processing. It is completely impossible to sync the inverters by using Bluetooth, as the (constantly varying/changing) latency can easily exceed the AC cycle by several times.
The current sync code with a direct wired feedback connection has a resolution of approximately 0.000041667 seconds (that's 41.6 microseconds). From some quick checks online, I have found ESP32 Bluetooth latencies varying from the lowest of 0.03 seconds (30mS, almost 2 full ac waves) all the way past a full second. It is fundamentally impossible to use this for sync.
I am thinking that we would be a lot better off switching both of your inverters to 120v single-phase out, and run them in split-phase sync mode. You'll still have 120v generator start/charge ability, but you'd actually have your pups pretty soon. That capability already works, and will do much better with surge loads.
Only catch being that if you want to run them off 2 separate battery banks, you might want to balance loads just a bit differently, or the weaker battery bank is going to get a pretty good load.
Right now I cannot in good faith release inverters with the not-properly-functioning parallel functionality to someone like you who is planning to use it to power their house.

Well, I was just thinking, I'm not the expert 😛 you are. Make sense on the dlay timing though. Too bad, Sean can't just solder on some kind of thing on the gs board and have a rj45 connect hanging out on both and run a cable that way or hell use a old cox cable terminal 😛 You can drill one small hole and use a double sided male connector with a nut to attach to the case and just use a cox cable between the inverts, that would give you two connections. Oh well,. I guess I'll stop throwing things at the wall to see what sticks 😛

Well, I was going to run both on the same battery bank, so that way I have the amprage, was going to connect all them to one GS inverter, then jump from it to the other with a 03awg cable which would be over kill since its only going to be less then 6 inches apart if that.
Right now I got 5 battery banks, up and running, each can push 100a, I also have a small 70ah 24v battery I mad that maybe can push out 10a if its happy? not sure, its cells that have two 18650 with a built in bms they are put in 7s with 16p7s at 24v then I got those two 18650 114ah packs just sitting doing nothing cause I was waiting to put some balancers on those before useing them.
I figured 500a would probley be enough for 10kw, as most things only run for a few mins.
Won't know until I get the inverts, that why I was seeing if you was even balanceing them. Its up to you Sid, If you need more time that is fine, it gives me more time to get other things ready for it. But, yes I was planning on running full time on them. and having a issue while I'm asleep on a Cpap machin would not be fun.
Also, while I'm thinking about it, that would mean I have to redo my wireing in the breaker box if you switch to doing 120v on both. not sure if they even make a 50a single pole breaker for my box. . .
Hmmm. what if you have the slave inverter set with l2 going to l1 and l1 going to l2 from the breaker. wouldn't that make the slave see l2 while master is seeing l1? not sure if that is even possble.
If that was a idea that would work, sean would only have to change the slave input wire to reflect that since I got l1 black wire, l2 other color wire I think red or yellow, and white for N. .

So no, the suggestion is not switching from split-phase output to single-phase output of the collective system.
Instead of trying to parallel 2 inverters for split-phase output, we switch gears.
Two inverters both running single-phase output, but synced 180 degrees apart from each other. "Master" runs L1 - N on your panel (and has 120v generator input, genstart control, etc). The "slave" inverter runs L2 - N on your breaker panel. "Slave" inverter's AC input wire goes to the Master L1 output (for a sync signal), and the "slave" inverter is set to Split-Phase mode--it runs exactly 180 degrees out of phase from the Master inverter.
This gives you a full 240v split-phase output, 12kw total, with good surge capability.
You can use the same 50A dual-pole breaker that you currently would be using for the inverters. One inverter runs one pole, the other inverter runs the other pole. Synced 180 degrees apart for a perfect 240v split-phase output.

Problem is, none of that was designed into the control board...so there's no "some kind of thing on the gs board" to solder to anyhow...
Figured out the bug causing frequency readings to be about 1/2 what they were supposed to...variable declaration mismatch...
But I seem to be able to reproduce the "80Hz" bug...not very pleasant sounding to get there, but it has happened a 2nd time. Still need to figure that out.
First tests of "master freq droop" from total output...well...it doesn't seem to be working right 😉
That's how it goes.

Ah, same thing Vioctron does. I figured that was what it should have been, but you was doing a different setup. so boh gets wired the same way? output l1 l2 and N tro the panel? then a l2 wir on the input for sense wire and l1 and n for charging? So I could in theriy have two 120v charging inverters? cause I do got another gen, a bigger one that I could use if it allow to use a none true sign wave gen as the ac for the other inverter. . . Its a 8.5kw honda gen.
Was 45 degrees last night...says it's up to 67 right now...
🤣 We won't even get to your high for our low. Summer is already here minus the rain. 93° in the shed with it opened up today at 1500.
