6 FAQs about [Photovoltaic inverter reverse tracking]

What is a photovoltaic inverter & how does it work?

The core function of today’s photovoltaic (PV) inverter is to harvest direct current (DC) electric energy from a solar PV array, convert it to useful alternating current (AC), and inject the harvested solar electricity into an AC power grid.

How can a PV inverter achieve 100% harvest efficiency?

Achieving 100% harvest efficiency requires the PV inverter to continuously harvest energy from the PV cells at their Vmp. For a homogenously irradiated PV module or array of identical cells this requires the inverter to operate continuously at the PV voltage that produces the characteristic singular maximum the Vmp is moving. The only way it can
