What does Equipment Tax mean?

Equipment Tax is Tigo's educational framing for added hardware complexity in some solar-plus-storage architectures.

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

This term is a shorthand for added hardware complexity in some system architectures. In engineering terms, more conversion devices, roof-mounted electronics, gateways, meters, breakers, or wiring paths can affect design time, installation labor, service access, and long-term maintenance.

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.
