What does Microinverter Tax mean?

Microinverter Tax is Tigo's educational framing for architectural tradeoffs that can appear in AC-coupled microinverter-plus-battery systems.

When does Microinverter Tax matter for TS4 module-level optimization and monitoring?

This term is a shorthand for comparing architecture-level tradeoffs, not a literal utility fee. In engineering terms, the comparison usually looks at where conversion occurs, how many conversion stages are required, whether excess PV energy can charge a DC-coupled battery, where serviceable electronics are located, and how equipment count affects system design.

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 TS4-A-O, TS4-X-O, GO Battery (US), GO Battery (EU), EI Inverter (US), EI Inverter (EU) only when current product documentation supports the application.
