[APP][Pro] SolarEdge + Growatt TCP modbus

Edwin_Biemond · September 25, 2022, 9:49pm

homey puts controls 1st , then sensors. also like to see this the other way around

Tobias_Antonsson · September 30, 2022, 3:57pm

What is the polling time set to? Can I change it?

Edwin_Biemond · September 30, 2022, 7:09pm

cannot change it now , lets see if I can change, provide that

biemond/solaredge.modbus/blob/main/drivers/invertor/device.ts#L6


      
          import * as Modbus from 'jsmodbus';
          import net from 'net';
          import {Solaredge}     from '../solaredge';
          import {checkRegister} from '../response';
          
          
const RETRY_INTERVAL = 28 * 1000; 
          
          
class MySolaredgeDevice extends Solaredge {
            timer!: NodeJS.Timer;  
            /**
             * onInit is called when the device is initialized.
             */
            async onInit() {
              this.log('MySolaredgeDevice has been initialized');
          
          
    let name = this.getData().id;

github.com

biemond/solaredge.modbus/blob/main/drivers/invertorwithbatt/device.ts#L8


      
          import * as Modbus from 'jsmodbus';
          import net from 'net';
          import { Solaredge } from '../solaredge';
          import { checkRegister } from '../response';
          import { checkMeter } from '../response';
          import { checkBattery } from '../response';
          
          
const RETRY_INTERVAL = 45 * 1000;
          
          
class MySolaredgeBatteryDevice extends Solaredge {
          
          
  /**
             * onInit is called when the device is initialized.
             */
            timer!: NodeJS.Timer;    
          
          
  async onInit() {
              this.log('MySolaredgeBatteryDevice has been initialized');

but becomes slower and then the time it takes goes over 45 seconds and the next run kicks in,

Hi,

I published a new version with a performance boost by not reading not used registers, meters(2,3) and battery(2).

now I can read it all in 5 seconds and can bring back polling to every 30 seconds for meters and battery.

Also it has now import limit control so you can make sure the battery is not supplying all the energy to your installation , always import when needed a certain amount from the grid and save some battery power for your peaks.

please try this.

thanks Edwin

I’ve added my SolarEdge but I don’t get any data… I’ve checked the IP, port and ID.
I’ve waited about an hour and I’ve check the SolarEdge app (for iOS) and it gives me data.

Edwin_Biemond · October 28, 2022, 9:14am

sorry for that , probably there is some explanation.

did you enable modbus like on the 1st post of this forum. Are you using a lan cable ? I guess that is the main part ( I guess you don’t have some kind of firewall )

plus know your ip and modbus port? maybe also check modbus id

after that you can send me diagnostic report so I can the communication.

Also there can be only 1 device at the time using modbus, 1 can block other devices who like to read this data.

I did this:

Go to the menu by the following steps:

Switch of the DC power

Long press the ‘OK’ button for a few seconds

Release the ‘OK’ button

The screen will ask a password, this is ‘12312312’ (the 2nd button from the left is ‘1’, the 3rd button is ‘2’, etc…)

Go to Communication → LAN Conf → Modbus TCP (the default port is 502).

To modify the TCP port, select Modbus TCP → TCP Port, set the port number and long-press Enter

I am using wifi. I do know my IP and port (502). I guess the ID is the site_id/installation_ide as shown in the web portal of SolarEdge?

I have no idea of Modbus devices.

Edwin_Biemond · October 28, 2022, 12:35pm

got it , you are lucky wifi works for you , I will make it more clearer it is the modbus id , mostly 1 and max 15 I think.

Erwin_DeB · November 17, 2022, 6:38am

I was a very happy user, but now it seems the fun is over. Went through all the settings in app and on the invertor. Searching online for all that I could find. That brought me to an update the SolarEdge invertor recieved late august/early september…

TCP Modbus connection is no longer available via WiFi. Can someone confirm this, before I start drilling holes in my walls to get an ethernet cable to my invertor

Glenn_Seegers · November 18, 2022, 10:02pm

From the solar edge firmware file from September:

Modbus TCP over secured Wi-Fi is now officially supported for residential inverters
- Modbus TCP over unsecured Wi-Fi is blocked
- Modbus TCP over Wi-Fi for commercial inverters is blocked
- Note: Modbus TCP over Ethernet and Modbus TCP over RS485 for all inverters are supported

Edwin_Biemond · November 19, 2022, 2:13pm

nice

Robin_van_Kekem · November 20, 2022, 8:29pm

Anyone tried it yet?

Glenn_Seegers · November 22, 2022, 8:16pm

Tried what?

Robin_van_Kekem · November 23, 2022, 11:57am

This

Glenn_Seegers · November 23, 2022, 12:46pm

i have everything cabled so no sorry.

Robin_van_Kekem · November 26, 2022, 7:47am

Looks like it, great!

Edwin_Biemond · January 8, 2023, 9:39am

Integrated with SMPL, very easy. I will publish a new version so all fields can be used on this display.

Edwin_Biemond · January 19, 2023, 2:55pm

if you want a display around 40 euros , check this [Homeyduino] E-paper for Homey

little bit more work, but a fun project and it is has usb-c connection no need for a battery . Also you can print your case

Koaz74 · January 19, 2023, 3:57pm

I am very satisfied

Koaz74 · January 21, 2023, 11:50am

I am not able to select the “power grid import” when I set the display layout to smpl
