MDLS Is the Answer.

TSS is an R&D organization, and manufacturer.

TSS created a proprietary MDLS

Module Level Shutdown is a safety feature designed to provide rapid shutdown in case of an emergency.

TSS is a proprietary MDLS designed specifically for preventing and containing solar fires.

Solar power systems are normally high-voltage AC. These systems are made up of delicate cells that carry electrons (electricity) through the bus. The bus is a conductive strip that connects the solar cells, and it provides an electrical path for the current generated by the solar panels.

Inverters convert DC power into AC. They continuously pump electrons through the system, so you have a mass. This often causes little shorts in the panels.

The Thermal Shield System offers a combination of a fireproof shield between the inverters and the roof, along with a mixture of module-level power electronics (MLPE) that detects unusual heat activity that can cause a fire, and it shuts down the system.

It disconnects the inverter from the solar panel system to contain the risk.

This safety feature is now an essential requirement according to the National Electrical Code (NEC) in the United States.

Recent advancements in technology have prompted the development of module-level rapid shutdown (MLRS) devices, which are designed to disconnect the inverter and provide rapid shutdown in case of an emergency. Module-level rapid shutdown devices have become increasingly popular among off-grid solar owners in recent years, according to a post on Reddit. The article highlights the lobbying efforts of Enphase/SolarEdge, who are pushing for the adoption of MLRS devices. However, for in-depth information, it is recommended to verify these statements with appropriate sources.
