Device description

Microinverter

Compact grid-connected inverter installed at one or several PV modules and converting DC energy to AC locally.

A microinverter is installed directly at a PV module or small module group and performs local DC/AC conversion and MPPT.

Important parameters include number of PV inputs, input and MPPT voltage ranges, AC output power, AC branch current, and the permitted number of microinverters on one branch circuit.

The system may use dedicated AC trunk cables, pass-through connectors, and daisy-chained branch architecture. Monitoring and commissioning may require a separate communication gateway.

Selection considers PV-module compatibility, AC branch architecture, power, communication requirements, rapid shutdown, and environmental conditions.
