I’ve got a nice solar panel setup on my roof, which uploads its data to the SolarEdge monitoring portal (this is the brand of inverter that I got). It appeared that this monitoring portal also has an API to automate getting the energy data. With me working in a company that works on energy savings, monitoring, consultancy etc, it’s a logical step for me to automate downloading the production of my panels, so my collueges at work can import this data in my energy monitoring portal at work and then they can do their magic calculations on them; which results in me getting nice graphs of my solar enrgy production.
The purpose of the tool:
I wrote this tool to be somewhat smart in what to download and what not. I only want to download the information if it’s up-to-date. Next to that, I’d want daily values, but also values with a 15 minute interval. In the end I’d want all the info to be exported to CSV files containing 1 month of data and/or 1 year of data. All files that have already been generated don’t need their data to be downloaded again and overwritten, thus it skips this data once it’s downloaded. In the end I can either mail these files or put them on a file share, so they can be imported by our energy monitoring system. This last step I’ve removed from the script that I share with you.
Several nice ‘techniques’ used in this script to get to the goal:
Since I’m talking with an API, the main important command is the Invoke-WebRequest with a pipe to ConvertFrom-Json
To get the last day of the month, the following line is used: $LastDayOfTheMonth = ((Get-Date -Date “01-$Month-$Year” -Hour 0 -Minute 0 -Second 0).AddMonths(1).AddSeconds(-1)).Day
(which will add a month to the date/time 01-<month>-<year> : 0:00 and then remove 1 second to get to the last second of the previous month, thus resulting in returning the last day of that month (<last day>-<month>-<year> 23:59:59))
In the end, the downloaded data is converted to CSV with this command: | ConvertTo-Csv -Delimiter “;” -NoTypeInformation (in Excel with localization the Netherlands, the semicolon is a better seperator than a comma, since Excel expects a semicolon. This saves me time on opening the csv files and converting the information to an excel readable file. Depending on your localization settings, you’d want to change this accordingly) I also add the switch -NoTypeInformation, since I’m not interested in getting information about the type of variable PS used, I only need the data.
Script parameters and bounds:
The script will check the solaredge portal for the date/time on which the installation received its latest data. If this date is not the same as today, something might be wrong. It’ll warn you about it, but will still download. If it’s out of date for more than 1 day, it’ll give an error about this, but the script will still continue. When no data has been downloaded, the tool will download all data (starting on the installation date of the inverter) per month and save these to csv files. It will also generate files with yearly data. The data that’s downloaded is from the previous month (unless this is a later date than the date the last data was received on the solaredge monitoring portal, then the last data date will be used). In case of the daily values (monthly and yearly csv’s), the tool will only store the value’s if they’re not $null (which is: no data received on portal or the solar panels with its optimizers as a whole aren’t yet initialized by the inverter). In case of the 15 minute interval values, all $null values will be replaced by 0,0 (in that case the inverter is turned off because of its night mode); thus giving a nice list of 96 readings each day, and resulting in about 2688 – 2976 values in each file, depending on the amount of days in the month (which can be checked for, if needed; in my case I don’t, since my work already has many comprehensive tools to check for gaps or strange behaviour in data).
The script can be found and downloaded here: DownloadEnergyData.ps1
Edit: I got myself an undocumented API call parameter from a SolarEdge developer, which gives me 15 minute values in WH 🙂 The script has been updated. (&TimeUnit=QUARTER_OF_AN_HOUR)

how can this tool be used?

You can download the file, then run it with powershell. If you want it to download automatically, then you can use the task scheduler to do so.

Hi, I’d really like to use this but it seems to throw up a series of errors when I try to run it – does the code still work?
LikeLike
Hi James,
yes, the code does still work.
Did you enter your SiteID and your APIKey?
If so, you probably use Powershell 2 or lower, but you need Powershell 3.0 or higher to be able to run this. To check which version you are using, you can check “$psversiontable” (without the quotes) when running powershell. This will tell you the current Powershell version (PSVersion)
You can find upgrades for your powershell here: https://docs.microsoft.com/en-us/powershell/scripting/install/installing-windows-powershell?view=powershell-6 (near the end of the page, there’s a table with different PS versions for each different supported OS)

Hi. looks like the energyDetails api can now give me Production, Consumption, SelfConsumption, Import and Export. Ive played around with the script but I cant not get it to convert to csv – I get error “Cannot bind to argument parameter ‘InputObject’
Im stuck on how I reference the energyDetails.meters.production.values
the JSON looks like this.
“energyDetails”: {
“timeUnit”: “WEEK”,
“unit”: “Wh”,
“meters”: [
{
“type”: “Production”,
“values”: [
{
“date”: “2015-10-19 00:00:00”
},
{
“date”: “2015-10-26 00:00:00”
Im at the very beginning of PowerShell learning curve so forgive my ignorance. As a side note what I am trying to do is create a total model of usage (PV, Tesla, heating etc) that I then integrate with time of use tariff data to calculate what my cost would be on each tariff.

Sorry for my late reply. I’m pretty busy at the moment as multiple areas in my life need(ed) my attention.
What you can do with the json return, is convert it, by putting ” | ConvertFrom-Json” at the end of the line, where you put the return in a variable.
Once you’ve done that, you can export the variable to csv, by using “$yourvariable | Export-Csv -path C:\yourpath\yourfilename.csv”
That way you should be able to make the information readable and exportable.

Yes, this is only a comment. At the time of writing the script, the technician from SolarEdge told me that they were always 6 digits (maybe he was wrong, but since mine is 6 digits, I didn’t know better), so probably the 6 digit range wasn’t sufficient enough and they’ve expanded on that.

It sounds like at the side of SolarEdge they don’t allow the web request (api call). I do know that if you do too many requests, they will disable calls for your API key and SiteID for 24 hours.
But if it is the first time you do a call, you could try to open the URL in your browser manually. In that case, enter this URL (for example): https://monitoringapi.solaredge.com/site/$SiteID/details?api_key=$ApiKey (and replace “$SiteID” by your actual site id, also you need to replay “$ApiKey” by your actual api key. Check if this gives you a result in your browser, of if it gives you an error.

I am making some progress. The script now generates a csv file but seems to be acing inconsistently. My system was first operational on Oct 18. Only 1 report was run this morning (Nov.1) and only had data (all 0’s) from 10-1 00:00:00 to 10-9. 23:45:00. There appeared to be only 1 report. I am still trying to figure it out. The last time I ran it, I received this message ”

Hi, it looks like you right-click the tool and use the “run with powershell” option. This way the script runs in C:\Windows\system32, which is a protected folder, so you won’t be able to save the files.
You shoult probably open the tool in powershell, in the folder you’ve saved the tool in and then run it from powershell. Or you should create a CMD file where you run powershell with the script as start-up parameter, so it’ll run in the folder where the tool is saved, instead of the c:\widnows\system32 folder.
The first option is the easiest, so right-click the file and choose edit, then, when powershell opens, choose run. And it should save all files in the folder.

Thanks for creating and sharing this PowerShell script. It worked perfectly for me running Windows 7 with PowerShell version 5.1.

I am getting partial results. month 1 have 31 values, month 2 have values up until day 1, month 3 have values up until day 2. month 4 have values up until day 3. etc.
Is it a date format setting issue?
My computer is set to region Sweden and swedish format
Short date = YYYY-MM-DD
I have checked the API data manually using an url and that data is complete.
I have tried to run the script from powershell and by rigth clicking the file and select run with powershell but the result is the same.

The date logic on line 72 assumes the date is DD-MM-YYYY. My computer sees MM-DD-YYYY. So for July it computed January 7th, then went on to return 6 as the last day of the month. My solution was to change line 72 from “01-$Month-$Year” to “$Month-01-$Year”. I don’t know enough PowerShell scripting to do that in universal fashion, I’m sure there is a way. Other than that, my hats off to the original poster, this script is exactly what I needed.

Hey Guys, this is some really cool stuff. I was looking around for python libraries and found some but for now I just want to get *all*¨my data in detail to slice and dice. This already works great, but I only get a limited period in my csv’s e.g. first 10 days of the month. Any ideas ? Sorry, I just moved, don’t have so much time right now to figure it out and if somebody has already the answer … Thanks. Points to the maker!

Above is someone that had the same. Seems that if your localization settings are “month-day-year” instead of “day-month-year” the script only collects the first few days. They’ve given a solution for this as well.

Wow, swift reply. Yes, I saw the discussion about the dates but I assumed (wrongly) that my regional settings where set to dd/mm/yyyy since I live in Belgium. I checked and it is set to mm/dd/yyyy indeed. And now I remember I had to change it to make sql server import/export wizard to import some other stuff correctly. (related to a bug but well) Thanks man, this will be the solution I’ll check it out and post.

I think i found another way to change line 72 so it is independent of your local date format.
Original code: $LastDayOfTheMonth = ((Get-Date -Date “01-$Month-$Year” -Hour 0 -Minute 0 -Second 0).AddMonths(1).AddSeconds(-1)).Day
Change to: $LastDayOfTheMonth = ((Get-Date -Date “01-01-$Year” -Hour 0 -Minute 0 -Second 0).AddMonths($Month).AddSeconds(-1)).Day
01-01 will be seen as the first day of the year as January 01 or 01 January depending on where you are, so no logic error. AddMonths($Month) will get you the first of the next month.

I ran into Powershell’s default TLS 1 issue
“Invoke-WebRequest : The request was aborted: Could not create SSL/TLS secure channel.”
the solution is to add this to the script
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

Hi,
I have tried to change the script to collect the Power instead as I understand is on the AC side and Energy is och the DC side. But I don´t succeed and I have not many skills in programming.

I’m a total powershell novice. Downloaded this some time back. Kept getting errors. Today I tried changing the output directory and in short order I got over 2 years of data; annual data, monthly data, daily data and data per month at 15min intervals. I still have little idea what I’m doing but will modify the script to suit my needs.
Brilliant, thanks

Hello, I have troubles using this script
can connect fine to the solaredge api via excel’s power query but whenever I run this script nothing happens, policy is set to unrestricted and I’m running it outside any protected folder. All I can see is something flashing for a split second then back to the powershell prompt and of course no files have been downloaded

Try and run it within powershell ISE, it’ll probably show you what went wrong.
I assume you did enter your API key and Site ID in the script?
