What does Dark start mean?

A term used in battery applications; it affects how stored energy is charged, discharged, backed up, or valued.

What should installers verify about Dark start in a solar-plus-storage design?

In solar-plus-storage systems, the term usually affects how PV production, battery charging, backup operation, utility rates, and load behavior interact. Good system design keeps energy flow, power limits, safety equipment, and user priorities aligned.

Practical design considerations

Separate energy capacity, power output, backup duration, and load priority; they are related but not interchangeable.

Why this matters for Tigo systems

This term relates to GO Battery (EU), GO Battery (US) only when current product documentation supports the application.
