⚡ Function in the Electrical System

ON-GRID / Grid-Tie photovoltaic system, single-phase 230 V. The MICRO is installed directly near the photovoltaic module and converts the panel's low-voltage DC into 230 V AC synchronized with the electrical grid. The MPPT control optimizes the operating point of the individual module; the microinverter architecture also limits the impact of possible faults at individual module/inverter level. Power-One documentation provides for connecting the MICRO units through an AC-TRUNK-BUS system and using a CDD concentrator for monitoring.

🏭 Construction and Installation

Compact construction in a metal housing for outdoor installation, with mounting bracket, DC-side connectors and dedicated AC connection. Cooling is natural and the IP65 rating allows outdoor use according to the installation conditions specified by the manufacturer.

🔎 Visible Markings and Identification
