Sol-Ark TX/RX Transmitter for 8K-2P and 12K-2P

Sol-Ark TX/RX Transmitter (TX-12K-A) for 8K-2P and 12K-2P

This is the part that makes a Sol-Ark 8K-2P or 12K-2P compliant with NEC 690.12 rapid shutdown. It generates the permission-to-operate powerline communication signal that tells SunSpec-certified module-level electronics on your roof to stay energised — and, critically, to shut down when the signal stops.

It works with Sol-Ark's O900-80V optimisers or any other SunSpec RSD certified module-level power electronics, and it can be retrofitted to a Sol-Ark 12K that was commissioned without one. Because the transmitter is built into the 12K's MPPT board, there are no separate PLC cores to install.

  • NEC 690.12 Compliance: Provides the rapid shutdown permission-to-operate signal required by the 2017 and 2020 National Electrical Code.
  • SunSpec Certified Compatibility: Works with the Sol-Ark O900-80V and any other SunSpec RSD certified module-level device.
  • No PLC Cores Needed: The transmitter is built into the Sol-Ark 12K's MPPT board, so there is nothing extra to install in the string path.
  • Retrofittable: Can be added to a Sol-Ark 12K that was already commissioned without one.
  • On-Board Powered: Runs from the inverter's 48VDC supply, with the power cable included.

Rapid shutdown requirements are set by your local code and enforced by your inspector, and they differ between jurisdictions and code cycles. This transmitter is specific to the 8K-2P and 12K-2P — other Sol-Ark models handle rapid shutdown differently. Call us at (303) 876-7654 with your inverter model and we'll confirm what your installation needs.
