Designed for residential solar applications, this Fronius inverter offers flexible power ratings ranging from 3.8 kW to 15.0 kW in a modern single-phase format. Its transformer-free architecture, combined with the user-friendly SnapINverter mounting system, allows for quick, secure, and straightforward installation. Two independent MPPT trackers, support for higher system voltages, and a wide DC operating range help extract maximum energy from the solar array. Built-in Wi-Fi and Modbus connectivity enable convenient monitoring and control. The inverter also accommodates an efficient rapid shutdown option to meet safety and compliance requirements. Active cooling, anti-islanding protection, and an adjustable-speed fan promote reliable and efficient performance. Compact dimensions and lightweight construction further simplify installation and ongoing maintenance.
