Add output to PVOutput with Powershell

In this article, we will see how to setup your PVOutput account in order to add output to PVOutput with Powershell.

I found a ton of info on how to add Ouput to PVOutput with curl, but nearly nothing (as I needed it) for Powershell. No wonder why I received a couple of questions on this.

If you’re the owner of a GoodWe inverter, take a look at Get GoodWe data with Powershell.

I don’t want to go too deep, so in this article I will just explain how to send data to your own system on PVOutput and how to set up the account to be able to do so.

Set your PVOutput account

In order to make API calls to PVOutput, against your system, you’ll need to enable API Access and generate a new API Key. You will also need the System Id you want to manage.

This is super easy as it’s all located in the same area of the account settings.

  • Login to PVOutput
  • Click Settings
  • Scroll at the bottom and:
    • Enable API Access
    • Click New Key to generate a new Key
    • Write down your system ID
    • Save

That’s it! We’re ready to send data to our system.

Note: Before proceeding, make sure your system is correctly set up. You need to ensure you’ve added the right amount of solar panels as well as the correct Watt hour or else you may end up receiving errors.

A very simple script

So, this script is very simple and will just show you how to send your system’s outputs to PVOutput. I strongly recommend adding a Try/Catch to make sure you Catch any error (so that you can also set up an alert, perhaps with Telegram: Automating Telegram Messages with Powershell) and, most importantly, you want to automatically get the date, time etc automatically (look at Get GoodWe data with Powershell to see how I grabbed these info from my inverter).

Super easy! You can add more functionalities, like I said above. One of them could also be checking for the Content (or Status/Description) that will be held in $PVOutputInvokeResult:

Have fun 🙂

Get GoodWe data with Powershell

I recently had a few solar panels installed over the roof of my house and right after that I thought, how can I get GoodWe data with Powershell?

GoodWe is the brand of the inverter installed, which connects to my home wifi and sends data automatically to the GoodWe Portal. The model I have is the GW4200D-NS.

I have to say that I wasn’t happy with the app I was provided with, neither was I happy with the portal, which refreshes the Real Time Data every 15 minutes! What kind of real time is that? However, to be fairly honest, why would you want to see actual Read Time readings? Well, because I want to. 🙂

Before looking for a solution on my own, I always search online, I don’t want to re-invent the wheel, so I found a post where I got the main idea: . This post describes a way of grabbing the data from a non-Windows environment.

Important: I am not (nor is the post above) grabbing the data directly from the inverter, but I am leveraging the GoodWe portal information. An idea I have is to sniff the traffic the inverter sends to goodwe, capture it and re-utilise it, however I’m not too interested in that yet as the solution I have works fine. (more…)
