daily-sungrow

This script lets you download your past daily reports from iSolarCloud (a product of Sungrow). It saves the daily data as CSV files, analogous to the manual download from iSolarCloud. We have added some extra columns.

For this to achieve the script uses GoSungrow to retrieve the data from iSolarCloud.

Install Node.js

The script of this project requires Node.js to run. (The script is written for Node version 22).

Prepare the GoSungrow executable

There is a Gist with instructions for building GoSungrow and further information: https://gist.github.com/Paraphraser/cad3b0aa6428c58ee87bc835ac12ed37

Build the GoSungrow executable

In summary, install Go and then run:

mkdir -p go-projects/MickMake

cd go-projects
git clone https://github.com/MickMake/GoUnify.git

cd MickMake
git clone https://github.com/MickMake/GoSungrow.git

cd GoSungrow

git remote add -t encryption triamazikamno https://github.com/triamazikamno/GoSungrow.git
git pull triamazikamno encryption
git switch encryption

go mod tidy
go build

You then find the executable here: go-projects/MickMake/GoSungrow/GoSungrow. Copy it into this project.

Connect to iSolarCloud

You need to configure your credentials:

./GoSungrow config write --user="..." --password="..." --host="..." --appkey="..."

The user name and password are those for the iSolarCloud. You find information about possible hosts and app keys in the (mentioned) Gist under Configuration.

Login via:

./GoSungrow api login

Configuration of daily-sungrow

Create the configuration files and make your personal adjustments:

• Copy config/config.sample.json to config/config.json. To find out your IDs/keys run ./GoSungrow show ps list.
• Copy config/nextdate.sample.txt to config/nextdate.txt. Set a recent date, for example today's date minus seven days.

Run the script

You should be able to run this script:

node index.mjs
