Tigo and SMA partner to bring a rapid shutdown solution to US market

US smart module technology provider Tigo Energy, Inc. and inverter manufacturer SMA have joined forces to deliver total compliance with the newly released SunSpec Alliance specifications regarding rapid shutdown adoption for PV plants in the USA. SunSpec Alliance, certifier of PV components and communication standards, has defined the specifications of the powerline-based PV transmitter signal covering varying installation types and regions.
According to the companies, »Tigo and SMA’s partnership brings the first transmitter and receiver offering representing interoperability« between the inverter and the PV module-level power electronics (MLPE). SMA‘s full line of US string inverters will be supporting the new SunSpec standard to fulfill the tightened module-level requirements in National Electric Code (NEC) 2017, becoming mandatory in January 2019.
Tigo will expand its current offering to include a SunSpec Rapid Shutdown and add this capability to its TS4 Flex MLPE product line, says the company. The new addition is compatible and certified by about 40 PV module suppliers currently using the TS4 platform – including Trina Solar, Itek, and Sunpreme. The new offering is also available for add-on or retrofit applications. The SunSpec specifications were developed by a workgroup of more than 75 solar professionals.
