Tigo 3.8 kW EI Hybrid Inverter 601-2103K8-0002

The Tigo EI 3.8kW Hybrid Solar Inverter | 601-2103K8-0002 is a single-phase hybrid inverter designed for residential solar power generation, compatible battery storage integration, and backup power applications. As a central component of the Tigo Energy Intelligence (EI) Solution, the inverter helps coordinate photovoltaic energy production and consumption when paired with compatible Tigo battery equipment.

Featuring 3.8kW rated AC output at 240V, 98.0% maximum efficiency, two independent MPPT trackers, and up to 200% DC oversizing capability, the Tigo EI Inverter offers efficient power conversion and flexible solar array configuration.

The 601-2103K8-0002 ordering configuration includes built-in Wi-Fi connectivity and compatibility with a 50A Automatic Transfer Switch (ATS). When integrated with compatible Tigo EI or GO Battery equipment and the required transfer switch, the inverter can support residential backup power applications.

The inverter also supports module-level monitoring, optimization, and rapid shutdown through compatible Tigo TS4 module-level power electronics. Its NEMA 4X/IP65 enclosure, natural convection cooling, and integrated electrical protection features provide a dependable foundation for modern residential solar and energy storage systems.
