1. Product Overview

The GTM-10/20/25/30-Li Series 10–150kVA lithium-battery modular UPS is a next-generation uninterruptible power supply system developed by GOTTOGPOWER (ANHUI) CO., LTD, purpose-built for deployments demanding both the flexibility of a modular UPS and the superior performance of lithium battery UPS technology. This lithium modular UPS system delivers Online Double Conversion (3P/3P, 3P/1P, 1P/1P) power protection across a scalable range from 10kVA to 150kVA, making it an ideal rack-mount UPS or standalone online UPS for small-to-medium data centers, edge computing sites, and distributed enterprise power infrastructure.

As a dedicated lithium battery UPS, the GTM-Li Series supports supercharging for high-capacity lithium battery packs, enables battery connection without Neutral for simplified high-voltage DC wiring, and delivers extreme power density of 30kW in a compact 2U module — minimizing rack space consumption while maximizing UPS system availability. With an Ethernet port built into the standard configuration alongside the 7-inch IoT touch LCD, this modular UPS system is designed for seamless integration into modern DCIM and smart building management platforms.

2. Key Features

• Lithium Battery UPS Support with Supercharging: The GTM-Li Series modular UPS is engineered specifically for lithium battery UPS configurations, supporting high-rate supercharging to rapidly restore high-capacity lithium battery packs and minimize downtime risk after a discharge event. It is also compatible with sodium-ion batteries, providing flexible support for emerging battery technologies.
• Battery Connection Without Neutral — Simplified High-Voltage DC Wiring: Supports neutral-free battery wiring, enabling cleaner, lower-cost lithium battery UPS cabinet integration and compatibility with modern HVDC energy storage architectures.
• Extreme 30kW/2U Power Density Modular UPS: Delivers 30kW of UPS output power in a 2U rack module, achieving best-in-class power density for space-constrained rack-mount UPS applications and reducing total infrastructure footprint.
• Zero-Disassembly 19-Inch Rack-Mount UPS or Standalone: Installs directly into a standard 19-inch rack without disassembly, or deploys as a standalone floor UPS — no tools required, supporting flexible data center UPS and office UPS deployment scenarios.
• 7-Inch IoT Touch LCD with Ethernet Interface: Integrated 7-inch color touch LCD with IoT functions and a built-in Ethernet port enables real-time UPS monitoring, remote management, and DCIM/BMS integration for smart power infrastructure.
• High Reliability — Component-Level UPS Protection: Multilayer protection at system, board, and component levels with strong environmental adaptability ensures maximum lithium modular UPS reliability across wide temperature and humidity ranges.
• THDi < 2% Input Current Distortion: Ultra-low input current distortion (THDi < 2%) minimizes harmonic pollution on the supply network, making the GTM-Li Series modular UPS ideal for sensitive shared-power environments.
