FAQ: Solar Power & Ostrom | Ostrom Help Center

📉 Why is my meter reading marked as invalid when I have a solar system?

If you installed your solar system after signing your contract, your new meter reading may be flagged as “implausible.”

This happens because your actual consumption is now significantly lower than the originally estimated usage due to your PV system.

👉 Solution:
Please contact us! We’ll check your meter reading and manually validate it for you:

Via chat
Or through the contact form

💡 Note for smart meters: If you have a smart meter, you don’t need to enter readings manually. They are sent to us automatically.

🔢 Can I view meter readings for both grid consumption and feed-in?

Yes. A smart meter is usually a bidirectional meter, measuring both your consumption and your solar feed-in.

Register 1.8.0: Power drawn from the grid
Register 2.8.0: Power fed into the grid

💡 Tip: On most digital meters, the display switches automatically.
Look for the counter number. Usually to the left or in one corner of the screen.

🔍 I see two readings, which one should I enter?

A smart meter measures both your consumption and your feed-in.

Register 1.8.0: Power drawn from the grid (consumption)
Register 2.8.0: Power fed into the grid (feed-in)

For Ostrom, only the grid consumption (Register 1.8.0) is relevant. That’s the value you should submit.

🔋 Does Ostrom offer a special tariff for solar systems?

Ostrom does not offer a specific feed-in tariff.

Your solar feed-in is not automatically offset against your electricity consumption.

However, our dynamic tariff “Simply Dynamic” is perfect for solar households:

Purchase power at hourly wholesale prices
Adjust your usage to sunny or low-price hours
Optimize self-consumption and save on costs

👉 Important: The feed-in payment is still handled by your grid operator, not by Ostrom.

➡️ Find more information about our tariffs on our website under Electricity Tariffs.

🧩 Which inverters and brands does Ostrom support?

You can find an up-to-date list of all supported brands and models here.

If your inverter isn’t listed, please send us the brand and model via our contact form or chat - we’ll forward the info to our product team.

☀️ Can I connect my solar system or battery storage to the Ostrom app?

Yes! You can connect your inverter directly in the Ostrom app. See below how it works.

🔗 How do I connect my inverter with Ostrom?

Here’s how it works:

Open the Ostrom app.
On the home screen, go to the “Solar Inverter” section.
Select “Connect inverter.”
Log in through our partner Enode in the new window.
Once you’re signed in, you’ll be redirected back to the Ostrom app.

A step-by-step guide is available [here].

📊 What information can I see in the app after connecting?

Once connected, you can view:

The current production rate of your solar system
The installation date
The total production since commissioning

You can filter your data by hour, day, or month. ☀️ 📆

The mobile Ostrom app interface displays real-time home energy flows from solar, grid, and battery alongside daily statistics showing solar production, consumption, and self-sufficiency.

🏡 Does Ostrom offer solar systems?

Yes – in the Ostrom Store you’ll find balcony power plants and solar kits for self-installation.

🧠 What is Enode?

Enode is our technology partner that enables the connection between your inverter and the Ostrom app.

It ensures secure data transfer and stable communication between both systems.
