What should installers verify about Keep-alive signal in a rapid shutdown design?
Rapid shutdown design is about reducing voltage in defined parts of a PV system after shutdown is initiated. The exact requirements depend on code edition, jurisdiction, equipment listing, system architecture, and manufacturer instructions, so published material should avoid treating one code phrase as universal.
Practical design considerations
- Use the term consistently across product pages, technical documents, and support content.
Why this matters for Tigo systems
for Tigo systems, this term is often connected to RSS Transmitter and compatible TS4 rapid shutdown devices. Use documented wording for code, certification, and compatibility statements.
