Sol-Ark TX/RX Transmitter TX-12K-A | Rapid Shutdown

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.
