Growatt ATS 11400T-US 50A Automatic Transfer Switch with Auto-Transformer for V2 Inverters

The Growatt ATS 11400T-US 50A Automatic Transfer Switch is an essential backup power management solution and autotransformer designed for Growatt home energy storage systems. Built specifically to pair with Growatt V2 series inverters (MIN 3000–11400TL-XH-US V2), this unit orchestrates automatic transition between grid power and battery backup during utility power failures, ensuring uninterrupted electricity to critical partial-home loads.

Key Features & Benefits

• V2 Inverter System Integration: Purpose-built to connect directly with Growatt MIN TL-XH-US V2 inverters for optimized system communication and instant outage response.
• Built-In Split-Phase Transformer: Features an integrated autotransformer that safely converts single-phase 240V power to 120V/240V split-phase AC power with up to 3,000W unbalanced load capability.
• Seamless Emergency Transfer: Automatically senses utility power loss and redirects stored solar/battery energy to key emergency circuits at up to 48A / 11.4kVA power output.
• All-Weather Wall-Mount Design: Housed in a compact, naturally cooled NEMA 4X (IP65) protective casing engineered for indoor or outdoor wall mounting.
