If you are a tinkerer and know/want to learn NodeRed then it's a good project, but except for this forum you are mostly on your own.

The Addon is tailored for Home Assistant. It's easier to use, quicker to setup and has additional functionality (filters, write UI elements in HA, full discovery/removal of entities). There have been some excellent contributions to the docs & code (like writable sensors).

Today you cannot update the time, but the System Mode is probably the main use case for adding the capability to write.

Hi @kellerza, I've installed the add ons whats the difference between standard and dev? I've decided to use a USR-W630 because my inverter is too far from the pi. Does anyone know what the configuration should look like for the Sunsynk add-on and the W630 interface?

@pedro54 The dev version has got all the latest features & it's been stable for a while

DEVICE: "select anything as port will take preference"
PORT: tcp://ipaddr_for_w630:502
DRIVER: umodbus
READ_SENSORS_BATCH_SIZE: 8

@kellerzaThanks do I need to set anything on W630? I'm getting errors when I start. I've wired up as per diagram

Hi all,

It's been almost a year since I started using these NR flows, and had no issues to date. However, this week I had my installer update my Sunsynk firmware, and now the flows are no longer working. 

These are the errors I am getting. Any idea where to start troubleshooting, or what might have changed in the more recent inverter firmware?:

Awesome, that did it. Thank you.

For future posterity, it is the "Modbus SN" setting in the advanced menu. Will require a restart of the inverter to take effect,

Hello all.

How to convert the registers (103-106) "Fault information word 1, 2, 3, 4" to "Fxx" error? In the protocol document is only "See the fault information coding table", but I can't find this.

Thank you

Hi all,

Does anyone perhaps have the Modbus address and description list for the Sunsynk 12kW, 3-phase inverter? The addresses are definitely different to those in the @Bloubul7 "sunsynk_modbus" Word document. It seems like they might tie up with the registers for the Deye SUN-10K inverter.

Thanks!

While it's not part of the addon at the moment, there are some users deciphering the 12kW inverter - Compatibility with Sunsynk 12kw 3-phase inverter? · Issue #63 · kellerza/sunsynk (github.com)

This is the latest version of the Modbus Doc, V118 

It talks about the 3 phase inverters in the doc has values for A,B & C Grid voltages so am assuming it has the updates data for the 3 phase inverters.

Thanks very much for the link. I managed to get comms to my 12 kW 3-phase inverter working. I had to use the "Meter-485" RJ45 port. There is another RJ45 that is labelled "ModeBUS", but according to the latest Sunsynk manual its use is reserved. 

The register addresses are definitely different to the inverters that you guys have done most of the development work on (except for the first few, so it is possible to get the serial number for example using the same registers). 

I did eventually stumble on the attached document on another forum that does seem to describe the 12 kW 3-phase inverter's Modbus register locations. I am still working through it to confirm everything. (I think this is the same document a poster mentioned on your github forum, but I'm attaching it here for anyone looking for it in the future.)

Thanks very much, but these Modbus addresses don't seem to tie up with the Sunsynk 12 kW 3-phase inverter as per the document in my previous post.

@pedro54 - did you figure this out in the end? I think I have a similar issue to you, although with a different setup.

So @AFTP,  maybe an idea to query the unlisted addresses on the 12kw 3-phase and see what it values it comes back with, there are not a too many unlisted addresses to try and I wouldn't think that they would use ones that are already allocated on the 5/8kw inverters.

Hi, no in the end I moved the pi next to the inverter and wired in directly to USB.

Thanks. I figured my issue out as well. It turns out the cable length was causing too much resistance, so the voltage would drop from 4.5v to around 4v. I used 2 wires for B and 2 wires for the A connection and that seems to have solved the problem.

Hey guys,

new to sunsynk (8kw inverter). Bought a RS485 to USB to setup the communication between inverter and my Pi powered Home Assistant. But I am struggeling to set up the MQTT plus the Sunsynk app doesn't start on it's own. Needless to say that in that way I couldn't figure out if the  (expensive) RS485 cable works. Anyone got experiences with this unit to share?

Thanks in advance

Hi there everybody,
I'm running a Deye sun 5kW hybrid inverter for a month. No batteries yet, but some loads are conected to the Load Output (essential loads).

I'm trying to figure out where the sensors are located over the hardware because some measures obtained via modbus are confusing to me.

I have drawn the following block diagram including the sensors where I think they should be placed. However, measures tell me I must be wrong  (e.g., Inverter output total power and Load side total power always match, even when part of the pv power is been sent to the grid and the rest to the essential loads output).

Furthermore, all power measurements drop to 0W when no PV power is available. The inverter goes OFF (running status goes "stand-by"), I supose this may be because I have no batteries installed yet. Loads remain grid connected, but no power measurements are obtained. The only measures available are Grid voltage and current, so I can compute the grid apparent power but not active (or real) power.

Hope you will help me some how.

Two questions: are you 100% sure exporting to the grid is what you want to do (if not don't worry apparently you havnt done so yet), and is your CT coil correctly installed on the main incomer?

Hi Scubadude,

No batteries yet, so the system is running as on-grid inverter exporting power excedents to the grid (I do, not a problem at the moment). CT coil is not connected, I could install-it but think my problem is to figur out why the internal measurements (Grid and Load power measurements) are lost when PV Power goes 0W. It is normal because the inverter switches to OFF or could it be related to a config problem? and, are the sensors located as I think?

Thanks a lot for your reply.

Hola sorts! I missed the Valencia bit earlier - of course export is much more feasible in Europe than it is in SA. The inverter cannot see your non-essential loads. So a CT coil is required to measure grid power consumption and selling to grid. Your inverter is not faulty - if it has nothing to do it records zero values.

Hola Scubadude,

Think you are right, I have installed CT coil and the inverter has measured the External Grid Total Power (172) until the sunset. At the time PV power has droped to 0, the inverter goes to stand-by mode, "nothing to do". It no longer carries out math computations like powers. I have an Eastron metter at the grid input side but I expected the inverter continue measuring grid and load powers at night.
Thanks a lot for your comments.

had a firmware update today and I was no longer getting the data into HA, found this and made the change and now getting data again, yay...
strange that the setting was the same on the previous firmware version so I guess they've update the firmware to actually check that now...

Just for info, when I changed that Modbus SN setting to be "01" and pressed the OK button my inverter went into fault mode and it disconnected the power to the essential load and I had to do a complete power off and reset on to get it functioning again, but at least I'm getting the data again...
