What happened
On 15 March 2024 a fire damaged a warehouse in Towaco, New Jersey that had a rooftop solar system, according to a subrogation complaint reported by Insurance Business. Advanced Solar Products had designed, procured and built the system in 2021 using TS4-A-2F rapid shutdown devices made by Tigo Energy. The insurer says it paid its insured, Corporate Mailings, more than 236,000 dollars and is seeking more than 241,000 dollars, including a 5,000 dollar deductible.
The complaint, which has not been tested in court, alleges that about seven rapid shutdown devices showed thermal damage within the first eight months and that a 2022 inspection did not raise possible signal interference between devices and inverters.
Contributing factors
The complaint alleges early improper string readings and thermal damage to rapid shutdown devices. It also alleges that a 2020 product manual did not warn about connector types to limit crosstalk, and that this was not raised at a November 2022 inspection. These points have not been tested in court.
Lessons learned
- Abnormal string readings should prompt an early check of rapid shutdown devices for thermal damage.
- Installation instructions should make clear any connector and string layout requirements intended to limit electromagnetic interference.
- After an early component fault, follow-up should record what was checked and what remains unresolved before the system stays in service.
