SMA Sunny Portal guide: How to monitor your system

Which version of Sunny Portal are you on?

The first step in using SMA Sunny Portal effectively is figuring out which version of the platform you’re actually on. SMA is in the middle of a multi-year migration from the original Sunny Portal (also called Sunny Portal Classic) to a newer platform called Sunny Portal powered by ennexOS. Both platforms are live right now, and many homeowners have no idea which one they’re using.

If you log in at www.sunnyportal.com and see a clean, white interface with a left-hand navigation menu and a modern design, you’re on the new ennexOS platform. If the interface looks dated, with tabs across the top and a slightly clunky design, you’re still on Sunny Portal Classic. Most systems registered after 2023 are on ennexOS. Older systems — especially those using Webconnect inverters — are being migrated on a country-by-country basis.

The good news: your login credentials work on both platforms if your system has been migrated. The bad news: some features work differently, and the layout is not the same. If you’ve been using Classic and suddenly find yourself redirected to ennexOS, don’t panic. Your data, settings, and system name all carry over automatically.

How to log in to Sunny Portal

To access your system data, go to www.sunnyportal.com or ennexos.sunnyportal.com depending on which platform you’re on. Enter the email address you used during registration and your Sunny Portal password. If you check the “Remain logged in” box, the platform will keep you logged in until you manually log out — convenient, but not recommended if you’re using a shared or public computer.

If you’ve never logged in before and your installer set up the account, you’ll need to contact them for your credentials or use the password reset feature. SMA’s system sends a reset link to the email address on file. If that email is your installer’s address and not yours, you’ll need them to forward it or update the account email.

One quirk: unlike Enphase Enlighten or the Tesla app, Sunny Portal is web-based only. There is an SMA Energy App, but it’s limited in functionality and primarily designed for systems with a Sunny Home Manager. For most monitoring tasks, you’ll be using a web browser on your phone or computer.

Reading your yield report and energy data

Once you’re logged in, the main dashboard shows your system’s current status and recent performance. The most important number for most homeowners is yield — the total amount of electricity your panels have produced, measured in kilowatt-hours (kWh). Sunny Portal breaks this down by day, month, year, and lifetime totals.

In Sunny Portal Classic, navigate to your system name in the top menu, then select “Yield” or “Energy and Power.” In ennexOS, click “Monitoring” in the left menu, then “Energy & Power.” You’ll see a graph showing production over time. You can toggle between different views: daily production by hour, monthly totals, or yearly comparisons.

If your system includes an energy meter (common in systems with battery storage or consumption monitoring), you’ll also see self-consumption, grid feed-in, and grid import data. Self-consumption is how much of your solar production you used directly in your home. Feed-in is how much you exported to the grid. Grid import is how much utility power you pulled when your panels weren’t producing enough.

Keep in mind: Sunny Portal data updates with a delay, not in real time. You’re typically looking at data from 15 minutes to a few hours ago, depending on your system’s communication method.

Setting up email alerts for faults and performance issues

One of Sunny Portal’s most useful features — and one many homeowners never set up — is automatic email notifications when something goes wrong. By default, most systems do not send alerts. You have to configure them manually.

In Sunny Portal Classic: Go to Configuration > Reports and Notifications. You’ll see options for Info Reports (scheduled daily or monthly summaries of your system’s performance) and Event Reports (alerts triggered by specific problems like inverter faults or communication loss).

In Sunny Portal powered by ennexOS: Navigate to Configuration > Notifications in the left menu. You can set up alerts at the system level or across your entire portfolio if you manage multiple systems. Click “Add notification” and choose what type of event should trigger an email: communication issues, inverter comparison alerts (when one inverter underperforms compared to others), or inverter faults.

For each notification, you can choose the severity level (liberal, tolerant, or sharp) and set the recipient email addresses. If you want a monthly summary of your system’s production sent to your inbox, set up a monthly Info Report. If you want to know immediately when your inverter goes offline, configure an Event Report for communication monitoring.

Important: if SMA’s system repeatedly fails to deliver emails to your address (due to a full inbox or spam filter), your email will be blacklisted and notifications will stop. Check your spam folder and make sure emails from sunnyportal.com are allowed through.

When an event number appears, our SMA error code guide explains what it means and what to do.

Navigating device overview and system settings

To see detailed information about your inverter, energy meter, or battery (if you have one), go to the Device Overview section. In Classic, this is under Configuration > Device Overview. In ennexOS, it’s under Configuration > Device Management.

Here you’ll find each piece of hardware in your system: the inverter model, serial number, firmware version, and current status. You can click into individual devices to see parameters like DC input voltage, AC output power, and operating temperature. You can’t change most settings from the portal — those are locked at the inverter level and require either physical access or the Sunny Explorer software — but you can view them.

This section is also where you’ll see if a device has gone offline or is reporting a fault. If your installer registered the system correctly, each device should show a green status indicator when everything is working normally. A red or yellow indicator means there’s an issue worth investigating.

If you need help troubleshooting an error or your system isn’t performing as expected, find a local SMA-certified installer who can access your system remotely or schedule a site visit.

Common frustrations and how to work around them

Let’s be honest: Sunny Portal is not as intuitive as Enphase’s Enlighten app or SolarEdge’s monitoring platform. It was designed for commercial solar farms and professional installers, not residential homeowners checking their phone over morning coffee. Here are the most common pain points and what you can do about them.

No mobile app. Sunny Portal works in a mobile browser, but the interface is not optimized for small screens. Buttons are small, graphs are hard to read, and navigation takes more taps than it should. If you want a better mobile experience, try the SMA Energy App — but be aware it only works well if you have a Sunny Home Manager installed.

Data delay. Unlike some competitors, Sunny Portal does not show live data. Depending on your system’s communication setup (Webconnect, Speedwire, or Sunny Home Manager), you might see a 15-minute to one-hour delay. This is normal. If data hasn’t updated in over 24 hours, that’s a sign your inverter has lost its internet connection.

Confusing terminology. Terms like “specific yield,” “performance ratio,” and “communication profile” are standard in the solar industry but foreign to most homeowners. If you’re not sure what a number means, focus on the basics: total kWh produced (yield), current power output (watts), and system status (online or offline). That covers 90% of what you need to know day-to-day.

Migration confusion. If your system was recently migrated from Classic to ennexOS and you’re struggling to find a feature you used to rely on, check SMA’s official migration FAQ or contact your installer. Some features — like Tigo optimizer monitoring or public plant links — are not supported in the new platform.

What to do if you can’t access your account

If you never received login credentials from your installer, or you’ve forgotten your password and the email on file isn’t yours, you have a few options. First, try the password reset feature on the Sunny Portal login page. If the reset email goes to an address you don’t control, contact your installer and ask them to update the account email to yours or forward the reset link.

If your installer is no longer in business or unresponsive, you can contact SMA’s customer support directly. You’ll need proof that you own the system — typically your installation contract, inverter serial number, or utility interconnection documents. SMA can update the account email or create a new login tied to your ownership.

If you’re buying a home with an existing SMA system, ask the seller to transfer the Sunny Portal account to you before closing. The easiest way is for them to add you as a user with full admin rights, then remove themselves after the sale. If they didn’t do that, follow the same process: contact the installer or SMA support with your proof of ownership.
