certification

SunSpec certification shows that a device conforms to a SunSpec interoperability specification. The best-known example is rapid shutdown equipment that responds to the SunSpec shutdown signal. SunSpec interoperability specifications are normative documents, so a product has to conform to them to support interoperability. Each specification moves through draft, test, approved and superseded stages. SMA publishes a technical information document that lists which of its inverters are approved for use with SunSpec Certified rapid shutdown devices. Check it before pairing an inverter with shutdown hardware. SMA names the JMS-F devices and the Tigo TS4-R-F receiver line as SunSpec certified rapid shutdown equipment that works with its inverters. On SMA inverters, set the rapid shutdown mode to SunSpec Shutdown when you use a PV array disconnect switch under the SunSpec interoperability specification.

<!-- review notes

Claims

issued_by

c1 drafted · lead SunSpec Alliance

Devices are labelled SunSpec certified; the SunSpec Alliance publishes the normative interoperability specifications that conformance is checked against.

review note: support check: partial - u11 says SunSpec Alliance publishes normative interoperability specs, but nothing states that the Alliance issues the certification or that devices are labelled certified by it (only that products are 'SunSpec certified').

c2 verified · fact JMS-F rapid shutdown device proposed

SMA calls the JMS-F a SunSpec Certified Rapid Shutdown Device.

c3 drafted · lead Tigo TS4 platform proposed

The TS4-R-F line is an SMA-compatible rapid shutdown receiver that is SunSpec certified.

review note: review: partial - The passage says the TS4-R-F line is an SMA-compatible SunSpec certified rapid shutdown receiver, but it never names Tigo and does not extend certification to the whole TS4 platform, so the claim's scope is wider than its source.
