Tigo 11.4 kW EI Hybrid Inverter 601-2111K4-0003

The Tigo EI 11.4kW Hybrid Solar Inverter 601-2111K4-0003 is a high-performance, single-phase hybrid inverter designed for residential photovoltaic energy generation, battery storage integration, and backup power applications. As a central component of the Tigo Energy Intelligence (EI) Solution, this inverter coordinates solar energy production and consumption when integrated with compatible Tigo battery equipment.

Featuring 11.4kW rated AC output at 240V, up to 98.5% maximum efficiency, four independent MPPT trackers, eight photovoltaic string inputs, and up to 200% DC oversizing capability, the Tigo EI Inverter provides flexible solar array design and efficient power conversion for larger residential photovoltaic systems.

The 601-2111K4-0003 ordering configuration includes built-in Wi-Fi connectivity and compatibility with a 200A Automatic Transfer Switch (ATS). When paired with compatible Tigo EI or GO Battery equipment and the required transfer switch, the inverter supports battery storage and backup power applications.

Designed for integration with the Tigo Energy Intelligence platform, the inverter supports module-level monitoring, optimization, and rapid shutdown through compatible Tigo TS4 module-level power electronics. Its NEMA 4X/IP65 enclosure, natural convection cooling, integrated AFCI protection, and comprehensive electrical monitoring features make it suitable for appropriately engineered indoor and outdoor solar installations.
