The STATE 1030 is a status code that means wired shutdown (wsd) open. For full troubleshooting steps, click here .

What is a STATE code on a Fronius inverter?

A STATE code is an internal diagnostic status displayed on Fronius inverters when a fault or condition is detected. Each code corresponds to a specific behavior or issue, and is used to aid in troubleshooting and maintenance.

Can I reset a Fronius STATE error code myself?

Some STATE codes clear automatically when the issue is resolved, such as after a grid fluctuation. Others may require a manual restart or service intervention. Always review the recommended solutions before attempting a reset.

Do I need to call an installer or technician for STATE code errors?

It depends on the error. Some STATE codes relate to grid voltage fluctuations or minor issues, while others may indicate wiring faults, insulation problems, or internal hardware failures. If you're unsure, or the error persists, contact your installer or a qualified service provider.

STATE 1030

Wired Shutdown (WSD) open

A device that is connected in the WSD chain has interrupted the signal line (e.g., surge protection device) or the bypass installed ex works as standard has been removed and no trigger device has been installed.

Expected Behaviors

The inverter is displaying a STATE 1030 message with a red or amber LED and is not currently operating. Due to the nature of the error and potential safety concerns, the inverter enters standby mode and requires user intervention before it can restart.

State Class

A state class is a generalized description of errors, catagorized by the number the STATE code starts with.

Class 1 Status: Grid Monitoring & Compliance
These errors are primarily related to grid parameters and external environmental conditions. The inverter's typical response is to stop generating power to comply with grid regulations, continuously monitor the grid, and automatically restart once conditions return to normal. No internal fault is usually indicated, it's more about protection and regulatory compliance. Persistent issues may require having a professional inspect the site wiring or grid quality. In a normally operating inverter, these errors typically refer to an issue the system detected externally, but in some cases may have been caused by an internal component failure.

If a external control is used, such as a remote shutoff switch, or surge protection device, ensure it is in the correct postion and check for any error states.

Tips for Qualified Persons

⚠️ Qualified Personnel Only

The following procedures involve safety risks and potential for equipment damage. They are intended only for qualified personnel trained to identify and avoid the hazards that exist, and possess the appropriate PPE. These are general tips to aid professionals in troubleshooting, not instructions or directives to perform them.
We assume no liability for injury or damage resulting from their use.

Inspect the WSD (Wired shutdown) inputs on the pilot card. Turn the switch to position 1 (WSD master). ensure in the user interface that the WSD switch is properly set to normally open or normally close operation. Inspect the trigger device to ensure it is properly opening or closing the WSD circuit. If the WSD is operated by a protective device such as a SPD, inspect the cause of the trigger event.

Fronius inverters in the U.S. typically come with a standard 10-year warranty. Starting in 2024, registering the inverter on the Fronius Solar.web website (the Fronius solar monitoring platform), extended the warranty by an additional 2 years, totaling 12 years of coverage, and updates the warranty start date to the actual installation date. Fronius has also offered warranty extensions of up to 20 years.

The inverter label, typically located on the bottom of the unit, lists the device serial number. To check if your inverter is still covered, call Fronius Technical Support at 1-877-Fro-nius (1-877-376-6487)

Founded in 1945 by Günter Fronius in Pettenbach, Austria, Fronius began as a repair shop for radios and electrical equipment. Recognizing the need for efficient battery charging, Günter developed a device to recharge car batteries, marking the company's first foray into energy solutions. Read More

In the 1950s, Fronius expanded into welding technology, introducing the first welding transformer with magnet-yoke control in 1950. This innovation allowed for continuous adjustment of welding current, setting the stage for future advancements in welding systems.

The company's commitment to innovation led to the development of the Transarc 500 in 1981, the world's first primary transistor-based inverter welding system, which significantly reduced power consumption. Fronius has since expanded into advanced welding automation recognized among key players in the industry, alongside firms like ABB, and Yaskawa Electric Corporation. Their current offerings include robotic welding systems, collaborative robots (cobots), and intelligent software solutions like Fronius Pathfinder, which provides functions for creating and simulating welding sequences.

In 1992, Fronius ventured into photovoltaics, releasing its first photovoltaic inverter, the Fronius Sunrise, in 1995. This move marked the beginning of Fronius's Solar Energy division, which has since become a cornerstone of the company.

Subsequent innovations include the IG inverter series in 2001, the SnapINverter technology in 2014, and the GEN24 Plus hybrid inverter in 2020, reflecting Fronius's ongoing commitment to advancing solar technology.

Today, Fronius stands as one of the top-tier inverter manufacturers globally, often ranked alongside SMA (Germany), in terms of quality and market presence. While companies like Enphase dominate the U.S. microinverter space and SolarEdge leads in optimizer-based MLPE systems, Fronius remains a leading choice for high-efficiency string inverter systems, particularly in Europe, Australia, and commercial U.S. installations. Their inverters have robust build quality, excellent thermal performance (with active cooling), long warranties, and strong service support. With over 3.4 million inverters installed and more than 35 TWh of clean energy produced, Fronius competes head-to-head with larger players, maintaining a presence in premium residential and commercial markets globally.
