Fronius Solar.web Guide 2026: Login, App, Premium and Codes

Fronius Solar.web is the free monitoring portal and phone app for Fronius inverters. You log in at solarweb.com (or with the Solar.web app on the Apple App Store and Google Play), and your installer normally adds your system with the separate Solar.start commissioning app. As at November 2026, a paid Premium upgrade adds extras such as forecasts and reports.

This is independent desk research from Fronius’s own pages and manuals; Solar Cobber did not test the portal on a live system, has no relationship with Fronius and was not paid for this guide.

Key facts

• Fronius Solar.web is reached at www.solarweb.com, and Fronius’s Solar.web page says the Solar.web app is free in its Basic version on the Google Play Store and Apple App Store (checked November 2026).
• Fronius’s Solar.web FAQ says one Fronius user account works across all Fronius platforms, so no separate Solar.web account is needed (checked November 2026).
• Fronius says Solar.web Premium is tied to your user account rather than to a product, is sold in terms of three months, one year or three years, and can only be bought directly in Solar.web, not through an installer.
• Fronius states that a Fronius Smart Meter is needed to show consumption data in Solar.web, such as the daily production and consumption charts.
• Fronius’s Australian warranty page says inverters commissioned on or after 1 June 2026 must be registered on Solar.web to qualify for the free 10-year Fronius Warranty Plus, and registration must happen within 30 months of delivery.
• Fronius’s GEN24 state code page lists code 1030 as “WSD (Wired Shut Down) triggered”, and says to update to the latest firmware before troubleshooting any code.

What is Fronius Solar.web, and what are the app names?

Solar.web is the cloud service that receives data from Fronius inverters, batteries, the Fronius Smart Meter and Wattpilot EV chargers. The same data appears in the Solar.web website, the Solar.web phone app and the commissioning app, but they are not identical products.

Table: Fronius app and portal names, from the Fronius Solar.web FAQ, checked November 2026.

Fronius says the Solar.web app and Solar.web desktop are separate systems that are only partly compatible, and that Premium features in the app are limited. Its FAQ recommends the mobile view in a web browser when you want the full Premium set.

How to log in and set up Fronius Solar.web

To use Solar.web you register at solarweb.com, confirm your email, then add your system or accept access to one your installer created. Fronius’s support page says you must complete registration before you receive system rights.

The steps, from Fronius’s support pages:

1. Open solarweb.com, choose Login, then Register Now, and confirm the email Fronius sends you.
2. Finish your user details at first login.
3. Add the system with the Solar.start app, or select “Add your PV system” on the Solar.web main screen.

Most Australian homes are commissioned by the installer. Fronius’s Australian commissioning tutorial for SnapINverter models (Primo and Symo) was published on its YouTube channel and shows adding the system to Solar.web over Wi-Fi. For hardware background, read our Fronius GEN24 Plus review and Fronius Primo review.

What are the owner, supervisor and guest roles?

Fronius defines three roles. Owners have full access, supervisors can edit most settings, and guests can only view. Owners can change ownership and assign roles under Settings, while supervisors can only grant guest rights. Fronius notes that a guest may not see the inverters at all.

How do I reset my Solar.web password?

Use “Forgot your password?” under the login field first. Fronius says that if this fails you contact customer service with the email on your account, and if you can no longer reach that email you must send a scan of a valid ID. A changed email also needs an ID scan, because it grants full access to the system.

If your installer has closed, you can still own the account yourself; see our tracker of Australian solar company failures for what a closure means for warranty, and find a local installer who services Fronius.

Free and Premium: what does Fronius Solar.web Premium add?

Solar.web Basic is free and covers monitoring, automatic reports and notifications and remote inverter updates. Premium adds on-demand reports, profitability and cost views, a two day production forecast, a weather display, presentation mode and support for flexible tariffs.

Table: Solar.web Basic and Premium, from Fronius’s Solar.web product page, checked November 2026. Premium is available in selected countries.

We could not find an Australian dollar price for Premium. Fronius says prices show next to each term when you choose it in Solar.web, and that you are told a month before a term ends. A free test membership also exists for a limited time and ends automatically. Fronius’s support page and product page differ on whether the direct consumption view needs Premium, so check your own account before assuming.

Fronius’s FAQ says deleting your account permanently removes your generation and consumption data. Fronius’s pages do not say where data is stored or for how long, so ask Fronius if retention matters to you.

Does the Fronius warranty extension go through Solar.web?

Yes. Fronius’s Australian warranty page says Warranty Plus is free for 10 years when the inverter is registered on Solar.web within 30 months of delivery, and covers materials, servicing and transport. A paid extension to 15 years is available within six months of the warranty start. The certificate appears under Product registration in Solar.web.

The video above is a Fronius Solar & Energy how-to showing product registration and the free warranty extension in Solar.web.

How to read the Fronius Solar.web dashboard

The dashboard shows what your panels make, what your home uses, what you send to the grid and, with a battery, its charge. Consumption and self-consumption figures only appear if a Smart Meter sits at your feed-in point.

Table: terms on the Solar.web dashboard. Fronius’s support page says that if the Smart Meter is hidden or has failed, only production is visible. Our guide to smart meters and solar explains the meter and why your retailer’s meter is a different device.

Common problems and fixes

Most Solar.web problems are connection problems: the inverter keeps generating, but data stops reaching the cloud. Fronius’s support page says a system shows “offline” when the inverter’s internet connection is faulty or interrupted.

Table: common Solar.web problems, from Fronius’s Solar.web support pages, checked November 2026. Power cycling a battery system involves isolating equipment in a set order, so leave that to your installer unless Fronius’s instructions for your model say otherwise. Lost history cannot be recovered after an update.

Fronius state codes: what do they mean?

A Fronius state code is a number the inverter shows on its display and sends to Solar.web, and many are routine. Fronius says to install the latest firmware before troubleshooting any code, and to check Solar.web for other messages at the same time.

GEN24 and GEN24 Plus. Fronius’s Australian state code page for the Primo GEN24 and Symo GEN24 lists these:

Table: GEN24 state codes from the Fronius Australia support page, checked November 2026. The page carries no date for the codes. Battery state codes (65000 series) and Solar.web codes 994, 995, 996, 997 and 999 are on separate Fronius pages.

Primo and Symo (SnapINverter). Fronius’s Australian page for Symo, Symo Hybrid, Primo and Eco lists these:

Table: Primo and Symo state codes from the Fronius Australia SnapINverter support page, checked November 2026. Fronius gives no document date. Fronius’s operating instructions for the Primo GEN24 7.7 to 10.0 kW (2026 copyright) have a “Status codes and remedy” chapter with the full list for that model; check the manual for your exact inverter.

What the numbers should look like

A Fronius system in Sydney should average around 3.9 kWh for every kilowatt of panels each day, while Hobart is nearer 3.5 and Alice Springs 5.0. These Clean Energy Council guide figures let you compare your Solar.web daily yield with an expected value.

Darwin	4.4 kWh
Perth	4.4 kWh
Canberra	4.3 kWh
Brisbane	4.2 kWh
Adelaide	4.2 kWh
Sydney	3.9 kWh
Melbourne	3.6 kWh
Hobart	3.5 kWh

Alice Springs gives the most output per kW of panels and Hobart the least, about 30% lower.

Solar Cobber calculation: multiply the figure by your system size. A 6.6 kW system uses 6.6 times the per kW figure, and the Clean Energy Regulator’s deemed rating (zone rating times system size, divided by 365) gives a more conservative floor.

Sydney	25.7 kWh	25.0 kWh
Melbourne	23.8 kWh	21.4 kWh
Hobart	23.1 kWh	21.4 kWh

On a clear day a healthy 6.6 kW system in Perth should land near 29 kWh, and a Melbourne system near 24 kWh. Our what size solar system guide has the sizing workings. The energy.gov.au figure for Sydney is 4.0 kWh per kW, slightly above the CEC figure used here.

Read the daily yield carefully. These are annual averages: summer days beat the average and winter days fall well below it. We did not source monthly figures for this guide, so judge against a rolling month, not one cloudy day. Persistent output well under the CER deemed figure, with clear skies and clean panels, is a reason to ask your installer to check shading, string faults or a failed tracker.

Third party monitoring and integrations

Fronius’s Solar.web FAQ describes Wattpilot charger data appearing in Solar.web when paired with an inverter in the same system. We did not check Fronius’s documentation for third party platforms such as Home Assistant or retailer and VPP control, so confirm compatibility with Fronius or your retailer first. Our guide to what a VPP is covers retailer control of batteries.

When to call your installer

Call your installer when a code repeats after a firmware update, when arc or insulation codes (240 to 243, 475, 502) appear, when output stays well below the expected figure, or when the system will not reconnect after a router change. Do not open the inverter, switchboard or battery yourself. If you need one, browse installers in our directory and see our guide to inverter repair and replacement cost. For the brand overview, see Fronius in Australia.

FAQ

How do I log in to Fronius Solar.web?

Go to solarweb.com, choose Login and enter the email and password of your Fronius user account. If you have none, choose Register Now and confirm your email. The same Fronius account works across Fronius platforms.

What is Fronius Solar.web Premium and is it worth it?

Premium is Fronius’s paid upgrade that adds on-demand reports, profitability and cost views, a two day production forecast, weather display and flexible tariff support. It is tied to your user account and sold in three month, one year or three year terms. Whether it is worth it depends on whether you use those extras, since basic monitoring is free.

Do I need a Smart Meter for Solar.web?

You need a Fronius Smart Meter at the feed-in point to see consumption data, according to Fronius. Without it Solar.web shows production only. Ask your installer whether one was fitted.

Why is my Fronius Solar.web offline?

Fronius says a system shows offline when the inverter’s internet connection is faulty or interrupted, for example after a router or Wi-Fi password change. The inverter should see at least 2 of 4 Wi-Fi bars. If a restart of the router does not help, ask your installer to reconnect the inverter.

What is the Fronius Solar.start app?

Solar.start is a Fronius app that guides you step by step through adding a PV system. You can alternatively select “Add your PV system” on the Solar.web main screen. Installers normally do this at commissioning.

What does Fronius state code 1030 mean?

State code 1030 means the Wired Shut Down (WSD) was triggered. Fronius says to check Solar.web for other messages at the same time, check whether an emergency stop switch was actuated, and otherwise contact your installer.

What does Fronius state code 509 mean?

State code 509 on a Primo or Symo means no energy was fed in for 24 hours, usually because of too little PV power. Fronius lists snow, dirt, leaves or night as causes and says to check the modules and DC switch. Call your installer if it keeps happening in good weather.

Does registering on Solar.web extend my Fronius warranty?

Yes, for the free Fronius Warranty Plus. Fronius says to register within 30 months of delivery, and inverters commissioned from 1 June 2026 must be registered to qualify. A paid extension to 15 years is also offered.
