Overview
The Growatt MIN 11400TL‑XH‑US is an 11.4kW grid‑tie inverter designed for high‑efficiency residential solar systems. With 98.5% peak efficiency, four independent MPP trackers, and support for up to 22.8kW of PV input, it handles complex roof layouts, partial shading, and high‑power module configurations. Its battery‑ready architecture supports future expansion with compatible Growatt and LG energy storage systems.
Details
This inverter delivers 11,400W of continuous AC output and supports dual‑string inputs per MPP tracker for flexible array design. It is compatible with Growatt APX, ARO, and LG battery systems for DC‑coupled or AC‑coupled configurations, including automatic backup switching.
The NEMA4X (IP65) enclosure supports operation from –13°F to +140°F, suitable for harsh environments including desert, coastal, and mountain regions. Integrated safety features include AFCI arc‑fault protection, rapid shutdown compliance, ground‑fault monitoring, anti‑islanding protection, and residual‑current detection.
Built‑in WiFi and 4G connectivity provide real‑time monitoring through Growatt’s mobile and desktop platforms.
