Tigo Energy 7.6 kW 50A ATS-Compatible String Inverter TSI-7.6K-US

The Tigo Energy EI Inverter 7.6 kW (Compatible with 50A ATS) is a hybrid, grid-tied inverter with battery support that orchestrates solar production, self-consumption, and backup power. With up to 200% DC oversizing, three MPPTs, and a rugged NEMA 4X/IP65 enclosure, it’s engineered for high yield and reliable operation—whether you’re building a new PV storage system or upgrading an existing array with Tigo TS4 MLPE and EI/GO batteries.

• 7.6 kW nominal AC power (240 V) with 32 A max AC output current (grid-tied)
• Backup-ready: up to 50 A max backup output current with GO Battery (300 ms duration); 38 A with EI Battery
• Up to 15.2 kW recommended PV input (STC) with 3 MPPTs; 2 strings per MPPT
• 600 V max DC voltage with wide 80–550 V MPPT range for flexible stringing
• Powered by the Tigo Energy Intelligence platform for module-level monitoring, optimization, and rapid shutdown (NEC 690.12)
• Built-in Wi-Fi (optional 4G) and quick app-based commissioning
• Listed to UL 1741 / IEEE 1547 and other key grid standards; revenue-grade metering (ANSI C12.20)

Hybrid control for solar storage

Pair with Tigo EI or GO batteries to store surplus PV and power critical loads during outages. The inverter manages production and consumption automatically, prioritizing self-use while maintaining grid compliance.

Flexible DC design, higher yield

Three independent MPPTs, generous string current limits, and up to 2:1 DC/AC ratio let you mix roof facets, long strings, or future module additions—without sacrificing performance.

Outdoor-tough and installer-friendly

The NEMA 4X/IP65 enclosure shrugs off weather for side-yard or garage installs. Thoughtful wiring space, quick-start commissioning, and integrated rapid shutdown streamline labor.

Works with 50A ATS

This 7.6 kW variant is compatible with 50 A automatic transfer switches for clean, code-compliant backup integrations and seamless source switching.
