SSEG & paperwork

What is inverter remote shutdown / NRS 097 signal support for SA home solar?

Some metro and NRS 097 contexts expect inverters to support controlled disconnect or export limitation so the network can manage SSEG — homeowners should confirm the quoted inverter’s compliance documents match the metro’s SSEG pack.

Updated 27 October 2026 · Illustrative ranges — not a formal quote, credit decision or legal advice.

Answer first: Ask for the inverter’s NRS 097 / grid-code compliance letter and the metro checkbox list. Export limitation and any remote/control features must match what was approved — export limit · SSEG · inspection · zero-export / export modes.

Remote shutdown and NRS097 expectations

Municipal embedded-generation rules increasingly expect a way to disconnect or limit export when the network asks. That may be a soft export limit via CT, a contactor, or OEM remote-control features — confirm what your metro’s SSEG pack actually requires. Smart meter will handle it is not a design. Document the shutdown path on the as-built for inspectors.

Ask for the NRS097 dual-supply labelling pack with the quote.
Test the export-limit setpoint with a temporary load method the OEM documents.
Firmware updates can reset limits — re-verify after every update — NRS 097 · export limit · labels.

Quick questions

Is remote shutdown always required?

Depends on metro and size — read the live SSEG PDF.

Is export limit the same thing?

Related but not identical — export limit caps kW; shutdown is a disconnect/control path.

Who configures it?

The registered installer against the approved settings.

Can I disable it?

No — that breaks approval and safety assumptions.
