What does Energy Conversion mean?

Energy conversion is the process of changing electricity from DC to AC or from AC to DC so it can be used, stored, or exported.

What should installers verify about Energy Conversion in a solar-plus-storage design?

Every power conversion stage has losses. In solar-plus-storage design, the number of DC-to-AC and AC-to-DC conversions matters because energy may move from PV to battery, from battery to loads, and sometimes back through grid-interactive equipment.

Practical design considerations

Check the term against the current datasheet and installation manual, not only a product overview.
Consider temperature, irradiance, string length, and equipment input limits before applying the value.
Use the same units and test conditions when comparing products or calculations.

Why this matters for Tigo systems

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