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.
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
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.
