Delta, a global leader in power management and smart green solutions, has launched its C-Series All-In-One Energy Storage Solution for commercial and industrial (C&I) applications. This innovative solution integrates LFP battery packs, a Power Conditioning System (PCS), a liquid cooling system, and a unit controller, offering a single-cabinet capacity of 125 kW / 261 kWh with a compact footprint of less than 1.5 square meters. It can integrate up to ten cabinets in on-grid operation for MW-scale energy storage. Its forklift-ready skid design eliminates the need for complex hoisting and underground trenching for cabling, significantly reducing on-site construction time and labour costs.

Harrison Yuan, Delta’s Head of Smarter Energy Solutions for Europe, Middle East & Africa (EMEA) region, said: “Branded as “Built to Simplify”, our Delta C-Series ESS’ peak shaving, load and energy shifting as well as power backup capabilities help to address rising energy costs, energy security concerns, and grid instability while delivering energy flexibility and the potential for additional revenue to users. With its safety-optimized, space-saving design and intelligent features, the system ensures reliable operation, easy integration, and efficient deployment.”
The C-Series ESS is designed to deliver:
Quick and easy installation: With its forklift-ready and skid design, the system avoids complex hoisting and underground trenching, streamlining installation while cutting on-site construction time and labour costs.
Advanced fire safety protection: With safety a key priority, the C-Series is equipped with a full liquid-cooled system, and benefits from gas-venting valves (inlet and outlet), the use of LFP 314 Ah cells, built-in heat, smoke, and flammable gas detectors, and fire aerosol protection.
Flexible configuration with a minimum footprint: At the core of the C-Series ESS is the PCS, seamlessly integrated alongside five battery packs, a liquid cooling system, and a control unit—all within a compact footprint of less than 1.5 m². This space-efficient design significantly reduces installation area requirements, making it ideal for sites where space is at a premium.
The C-Series is equipped with an integrated unit controller that streamlines device-level coordination - enabling flexible site planning, simplified maintenance, and efficient operation. By managing routine control functions at the cabinet level, it frees up the central energy management system (EMS) to focus on strategic decision-making and AI-driven optimization. The system also supports multiple application modes and allows for seamless integration with third-party EMS platforms. Built with high-performance LFP 314 Ah cells, the C Series is designed as a long-term investment. It combines a long cycle life with high energy density and complies with the UL 9540A testing method, ensuring it meets rigorous fire safety and building code standards for battery energy storage systems.
The C-Series is designed for easy installation and transport. Equipped with 314 Ah LFP cells, an advanced liquid-cooling system for both PCS and battery packs, and multi-level fire protection, the system ensures superior performance, safety, and long-term reliability.
