Microinverter Tax
The Microinverter Tax is Tigo’s name for the combined performance and equipment penalties that can occur when high-wattage modules and batteries are paired with AC architecture.
What does Microinverter Tax mean?
The Microinverter Tax is Tigo’s name for the combined performance and equipment penalties that can occur when high-wattage modules and batteries are paired with AC architecture.
Why does the Microinverter Tax matter for solar-plus-storage projects?
The idea groups three losses installers and system owners often ask about: clipping from module-level inverter limits, conversion losses from extra AC-to-DC-to-AC steps, and additional hardware required to make solar and storage work together. It is not a literal tax from a utility or government; it is a useful shorthand for energy and equipment value that can quietly slip out the back door while nobody is looking.
How it relates to Tigo
Tigo uses the concept to explain why DC optimizers, hybrid inverters, and DC-coupled batteries can help residential systems capture more watt-hours with fewer unnecessary conversion steps.
