New project proposal: Integrating inverters and various energy meters into IAMMETER

We are committed to advancing the 'Integrate the data of the Solar inverter to IAMMETER cloud' project.

If you currently utilize a solar inverter and are considering transitioning its monitoring system from the official portal to IAMMETER. We kindly request the following information:

  1. The brand and specific model of your solar inverter.

  2. The local protocol it operates on (Modbus/RTU or Modbus/TCP) or the availability of a local API for the device.

  3. The API interface details of the official portal (if they provide it)

    Your cooperation in providing the above information will greatly assist us in implementing the most suitable integration method for your solar inverter's transition to IAMMETER


    There are three potential approaches we can undertake:

  1. Extracting data from the official portal's API (if provided) and establishing a bridge to transmit this data to IAMMETER.

  2. Utilizing open-source hardware, such as ESP32, to locally retrieve data (if the inverter supports a local protocol like Modbus/RTU or Modbus/TCP) and subsequently uploading this data to IAMMETER. This approach will be developed in an open-source capacity.

  3. Utilize either Home Assistant (HA) or Node-RED as an intermediary to facilitate integration. Create an integration within Home Assistant(or a corresponding node in Node-RED). This setup will allow us to access and extract data from the inverter, supported by either Home Assistant or Node-RED, and subsequently upload this data to IAMMETER-cloud.

    Please let me know your preferred mode among the three options.

    It's crucial to highlight that while the initial focus is on the inverter, we aim to encompass all devices related to energy measurement, including energy meters from different brands.We aim to develop a method that enables all energy measurement devices to seamlessly upload their data to IAMMETER-cloud. Your valuable insights and suggestions regarding this expanded scope are highly anticipated and deeply valued.

Estou bastante interessad nessa possibilidade, uma vez que atualmente tenho que consultar 3 portais diferentes para ver o balanço de energia do meu site.

Tenho o IAMMETER, o Solarman para o inversor SUN2000G3 e em modo local inversor MPI3000WPLUS via Esp32.

Lembro que sou um engenheiro eletronico aposentado e no caso do inversor MPI3000WPLUS,  que tem protocolo fechado, desenvolvi meu proprio drive de comunicação serial usando um Esp32.

Estou fortemente inclinado para o protocolo Modbus/RTU ou Modbus/TCP.

Deixe-me saber, se precisar de mais informações.

1. Goodwe SDT G2 15kw Ongrid (3 phase) and Deye 8kw Low voltage hybrid (single phase).

2. Will confirm and get back.

3. Both have their own portals which are very basic, Ive never heard of them providing their portals api. I logon using "Sems Portal" app for Goodwe and "SolarMan Smart" for deye. Both do have web logins as well.

I know Rasberri Pi can be used with Deye to grab realtime data, not sure about goodwe.

Hi, I am using the Growatt 5000 TL3-S inverter. It uses a wifi dongle to upload data directly to their cloud (https://server.growatt.com/)
I found a link to their API integration but I am not sure how up to date that is. https://growatt.pl/wp-content/uploads/2020/01/Growatt-Server-API-Guide.pdf

So the preferred option would be to extract the data directly from their database through their API.

How would you store the data and how do you plan to display and integrate the data from the inverter on your platform? I am actually already tracking the PV production with a three phase meter from you. So would it not be duplicated data? Or is the idea, that once you can import the data from the inverter, I wouldn't need the three phase meter anymore to read the same data? And the energy data from the inverter itself is probably also a but mofe accurate?

Please let me know how you plan to implement that feature exactly.

Thank you and kind regards,

Martin


I also think that cloud-to-cloud communication would be the most user-friendly solution as many people do not want to run and administer a raspberry pi. Cycle-times could be lower locally though. I for example like how clever-pv does it. Everything is via cloud, also the triggering of a Shelly relay.

For me personally, I do have a raspberry pi, running my own excess energy task. I use Modbus TCP to access all data from the Huawei PV, also including battery charging/discharging power and smart meter import/export. I also do calculations based on the readings of the Huawei and IAMMETER smart meters.

Hi Martin:

"How would you store the data and how do you plan to display and integrate the data from the inverter on your platform? I am actually already tracking the PV production with a three phase meter from you."

If you have already installed two energy meters, one on the grid and one on the inverter side, you may not need to consider this option. However, this idea is specifically aimed at customers who have only purchased and installed a single energy meter on the grid side. These customers wish to monitor both the grid and solar aspects through IAMMETER, while also utilizing an existing official solar monitoring service.

In scenarios where purchasing an additional energy meter for the inverter side might seem redundant due to the existing official solar monitoring system, we propose a solution. Our plan involves enabling customers to directly retrieve data from their official solar monitoring system and transmit it to IAMMETER-cloud. This feature eliminates the need to buy another energy meter, offering a more cost-effective solution. Instead, customers would only need to subscribe to this feature, ensuring a more efficient and economical approach.

Hi Daniel:

Thanks for sharing! Cloud sounds great to us too—it's so user-friendly. We're thinking of backing both cloud and HA bridge modes at the same time.

I'll dive into checking out 'clever-pv,' the thing you mentioned. And about triggering a Shelly relay through the cloud, that's interesting! I'll definitely take a look into that.

Any other cool gadgets like the Shelly relay that you think we should explore for IAMMETER? We're open to gathering ideas for our actuator proposal!
