Please see the new version of this video at kzbin.info/www/bejne/e3-YeJ17l7JnnNE It includes a better explanation of the onboarding process and a new RS485 board which is much better.

[@kevinrtres]

As a newbie- just want to say a great thank you to you and all the other guys on the power-forum for the hard work you've put into this - sorting out all the glitches. Now I can just copy and use without having to re-invent the wheel. *Thanks a LOT!*

[@SolarIntegrations]

Thanks @kevinrtres I am glad you found it useful. There are a lot of smart guys on the Power Forum that did all the heavy lifting, working stuff out when there was no one else doing these things. Is definitely an organic process and everybody in the community contributes to moving it along so the way I see it the more people doing the automations and working things out the better.

[@vaughanza]

Looking forward to the dashboards , excellent thanks

[@SolarIntegrations]

Coming soon!

[@capetownkelp]

I would just like to point out that the ESP32 is a 3.3V device that is *not* 5V tolerant. Interfacing it to the 5V MAX485 chip on the recommended Microrobotics RS485 board is therefore not a "safe" option, and is likely to damage the IO buffers on the ESP32. To use these boards together, I suggest the following: Remove R1, R2, R3, and R4 (pullups to 5V). Add a series 330 ohm 0603 resistor, and mod a 680 ohm 0603 between the RO trace and GND on the back of the board (scratch off solder mask to create "pads" for this) to form a voltage divider. This could well be why so many people are having issues getting this working. I really think you need to highlight this to your audience.

[@SolarIntegrations]

Thanks @cliffordvandyk3728 , wondering if a better option might be to look for a 3.3v ESP32, not sure if there is even such a thing

[@capetownkelp]

@@SolarIntegrations the ESP32 is 3.3V, the MAX485 level translator is 5V. The solution is to implement a "level translator" between the two devices. By removing the 10k pull-up resistors on the RS485 module, you prevent the output pins of the ESP32 from being pulled up to 5V before they are configured to actively drive the MAX485, that could otherwise damage the ESP32. The MAX485 inputs can happily tolerate the 3.3V outputs of the ESP32. In the reverse direction, the RO output of the RS485 drives the ESP32 at 5V, so a simple 1:2 ratio resistor divider does the level translation. The other option is to replace the MAX485 with a 3.3V equivalent device that is footprint compatible.

[@SolarIntegrations]

Thanks for the info @cliffordvandyk3728 , I am going to have to have a look around for a 3.3V RS485 board and see if one is available. I have however been using a MAX485 with my ESP32 for the last 18months without issue so not sure that it is a problem that has to be solved.

[@capetownkelp]

@@SolarIntegrations I think it might be luck of the draw, along with subtleties of implementation, as to whether there is damage or not. I design high reliability electronics for a living. I have modified the PC board to fix the issue, rather than risk damage to the ESP32 or (very much less likely) the inverter. The fix is straightforward if you are familiar with soldering surface mount devices. Happy to send you a pic if I can figure out how!

[@SolarIntegrations]

Thanks @@capetownkelp that would be great, I think 1st prize would be to find a 3.3V RS485 board that we can use but being able to modify a MAX485 so it would cause no issues would be a close 2nd :-)

[@AA-vn2ip]

I hope this helps someone. Sunsynk like to play musical ports it seems. on the newer inverters (the 8kw one in my case), you cant use the RS485 port. you have to use the CMS port to the right. It is two ports in one. You can buy a splitter so you can plug your batteries in also. Note if using the orange & orange/white cable make sure the brown cables don't go to the batteries.

[@jacoannandale3307]

Which splitter are you using? can you give more info please?

[@AA-vn2ip]

@@jacoannandale3307 I bought a splitter but it didn’t work for some reason so I spliced together my own cable (made my own splitter) and it worked great.

[@FransStofberg]

As part of the fault finding tips... I can add that last resort remove R7 resistor. I was getting erratic data until I removed it.

[@SolarIntegrations]

Hi @FransStofberg, that does seem to be what most people are experiencing. I think that the inverters usually have a terminating resistor built in. I have removed the resistor on all of my installs.

[@capetownkelp]

You might want to remove R1-R4 too, and replace with a voltage divider to reduce the 5V output on RO to 3V3. ESP32's are 3.3V devices that can't tolerate 5V on their I/Os.

[@kevinrtres]

Just a heads-up - robotics says the Dev board has been superseded by the one with a USB-C port - ESP32-DEV-CH340-C. However I see on their website there's also a ESP32-DEV-CP2102-C which is somewhat confusing since you mention one should look for the CP2102 interface when installing it. Not sure what the CH340 is for.

[@SolarIntegrations]

Hi @kevinrtres , Thanks for pointing that out, I don't think that it makes much difference though as the only time you will use that interface is when you are onboarding the ESP32 into ESPhome. Basically you just look for the inteface that appears when you plug it in.

[@jolambinon9775]

Rgere are a number of ways you can see a full list of the entities being brought in by any Integration, have a look in the settings/integrations/ menu and then click on the relevant integration, it will list the names of all the entities it is responsible for with their name. You can also check the states/values of those entities by going to the Developers Tools menu option and then clicking on States and then filter the entities with the name of the entity you are looking for, it will show you the current value of that entity. I hope that answers your question. You can also rename entities if you want in the settings/integrations and then click entities at the top of the page, you can drill down and change names etc there.

[@SolarIntegrations]

Hi @schwarzimker5257, I assume you have three inverters you want to connect? To be totally honest, I am not 100% sure but I think that you might be able to just daisy chain the RS485 connection to each of the inverters, query each inverter individually based on their addresses on the RS485 bus and avoid having to buy 3 x RS485 board. I would strongly recommend using the ESP32 Shield as they have a LOT less problems with installation. Is featured in my video, "a better way to connection Home Assistant". Maybe have a chat to the guys on the Powerforum as there are a load of people there with more experience than me in RS485 connections.

[@BradsJardine]

Bought my electronics today but I think I’m am missing a step. At what stage do you unplug from the computer and into the inverter and does it need power once plugged into the inverter?

[@SolarIntegrations]

Hi @BradsJardine , the ESP32 does need it's own power supply. I tried to house my ESP32 inside of my inverter but that did not work well and I think I picked up too much interference from the inverter. Better to have along cable from the RS485 board to the inverter. Once you have the ESP32 onboarded to ESPhome and it is connecting to your wifi network it does not need to be connected to the computer any longer and you can send updates to it over the air via wifi network. Give us a shout on the power forum if you get stuck at all.

Hi all, what is the prefered and neatest way to power the esp32, specifically for the use with a 5kw sunsynk inverter?

[@SolarIntegrations]

Hi @XianZA, the new ones are powered by a USB Type C, I have my one inside the inverter but had all sorts of issues with signal interference, best to have a longer cable to the RS485 board and just keep it closer to the power supply I think.

[@XianZA]

Ok but are you getting power from somewhere in the inverter or from a plug socket. Reason I ask is that all my outlets are far from my inverter.

[@SolarIntegrations]

@@XianZA I get mine from a plug socket, you can make the RS485 cable quite long without an issue, up to 50mtr depending on the cable quality etc.. Would start with a short one, get everything working and then see if you can make it long enough to get to a plug, just remember it need to be a twisted pair to work.

I feel sorry for someone new to this trying to figure out why things are not working.

[@SolarIntegrations]

Hi @MS-dx1zl, I wish it was that easy :-) . The Yaml files are all based on the Modbus register which we managed to get from Sunsynk, it details which modbus address is for which value. Queries are sent to the inverter asking it for the value for a specific address, 186 for example is the address for PV1 power. Most of the Sunsynk inverters seem to use the same register and people have written the various integrations mostly built around this register. The register contains values for the single phase and 3-phase inverters and these are mostly what has been used for creating the yaml files that you have spoken about. I haven't seen a 10kw 3-p as yet but don't see any reason why they would change the register for it as it seems to be stable. My suggestion is to get onto the powerforum website at powerforum.co.za/topic/17970-home-assistant-sunsynk-power-flow-card-and-dashboard/ and have a look through the thread, if you can't find any solution, post a detailed log from the ESP32. the more information you are able to provide the more likely it is that someone will be able to assist you there. Good luck and see you on the site
