Meet safety requirements. Improve project ROI. Get multi-vendor flexibility from the leader in rapid shutdown technology.
The Tigo TS4 Flex MLPE (Module Level Power Electronics) platform enables rapid shutdown at the module-level to meet safety code requirements and for use in solar maintenance situations. By shutting down electricity flow at the module level, installers, firefighters and maintenance techs have confidence that voltage has been reduced to safe levels on the roof. With multiple patents issued and tens of thousands of sites deployed around the world, Tigo is the global leader in rapid shutdown technology.

Rapid shutdown requirements have been enacted for the safety of firefighters and other first responders that access the roof where live solar modules may be operating. The code is specific about reducing the voltage of the array in order to minimize risk for these groups in the event of grid power loss or manual rapid shutdown so the roof can be accessed safely.
1. Rapid Shutdown Device (RSD)
Stops the voltage at the module level. May communicate over PLC (Powerline Communication) or wirelessly with initiator.
2. Rapid Shutdown Initiator
Initiates the rapid shutdown process when the keep-alive signal it transmits is no longer detected by the RSD
3. Certified Inverter
Inverter must be certified with the Rapid Shutdown Device and Initiator. The Initiator is often located inside the inverter wirebox.
Upon grid power loss or rapid shutdown initiation, the following requirements must be met within 30 seconds:
In addition, the code requires rapid shutdown equipment (PVRSE) and systems (PVRSS) be UL Listed by a Nationally Recognized Testing Laboratory for rapid shutdown.
The Rapid shutdown requirements enacted by the US National Fire Protection Agency as part of the National Electrical Code are being replicated and enacted in countries throughout the world including Canada, Mexico, Philippines, Thailand, Poland, and more.

Tigo TS4 units are connected to each module. Customers can selectively deploy any combination of the TS4-A-O, or S products to maximize returns for their particular site.
Tigo's Cloud Connect Advanced (CCA) is the data hub for TS4s and other devices(inverter, battery, etc.). It connects with an RS485 cable to the TAP which wirelessly communicates with TS4s.
All of the module-level data, and any third party data connected to Tigo's CCA can be viewed in Tigo’s Energy Intelligence monitoring system.
Tigo's Fire Safety line of TS4 are completely dedicated to the rapid shutdown function and communication via PLC with the RSS Transmitter.
The Tigo Rapid Shutdown System (RSS)Transmitter enables UL PVRSS certified rapid shutdown with TS4-A-F and 2Funits to meet required safety codes.
Tigo's TS4-A-F and -2F are dedicated rapid shutdown devices. Inverter monitoring may provide DC data at the string, MPPT or array level.
