Sol-Ark TX 15K-A TX/RX Transmitter for Limitless-15k

Sol-Ark TX 15K-A Rapid Shutdown Transmitter (TX 15K-A)

The Sol-Ark TX 15K-A is an internal powerline communication (PLC) Rapid Shutdown (RSD) transmitter designed specifically for installation within Sol-Ark Limitless 15K (15K-2P-N) hybrid solar inverters. Operating as the transmitter core of a SunSpec-compliant Rapid Shutdown System, the TX 15K-A broadcasts the required "permission-to-operate" signal over PV DC lines to satisfy NEC 2017 and NEC 2020 690.12 array de-energization requirements.

Integrated directly into the MPPT board structure of the Sol-Ark 15K, the TX 15K-A eliminates the need to install external PLC ferrite cores or external signal couplers. Compatible with Sol-Ark O900-80V receivers and all third-party SunSpec RSD Certified module-level power electronics (MLPE), it accommodates up to 6 PV string inputs and supports up to 30 RSD receiver devices per string channel.
