The C-Series prioritizes safety by including an advanced liquid-cooled system complemented by gas-venting valves and LFP 314 Ah cells. It also includes detectors for heat, smoke, and flammable gases and is equipped with fire aerosol protection capabilities.
The PCS is central to the unit, paired seamlessly with five battery packs, ensuring an efficient and compact configuration. This integration is vital for sites where space is limited.
Advanced Control and Compatibility
The design offloads routine control functions to the cabinet level, allowing the central EMS
An integrated unit controller enhances device-level coordination, which facilitates easier site planning, streamlined maintenance, and efficient operation.
The design offloads routine control functions to the cabinet level, allowing the central energy management system (EMS) to prioritize strategic decision-making and AI-driven optimizations.
Moreover, the system supports various application modes and is compatible with third-party EMS platforms, ensuring versatile operation.
Compliance and Long-Term Durability
Constructed with high-performance LFP 314 Ah cells, the C-Series is engineered as a long-term asset. It boasts a long cycle life and high energy density, while complying with the UL 9540A testing method, meeting stringent fire safety and building standards for battery energy storage systems.
The equipment's transportability and straightforward installation, combined with its advanced cooling and comprehensive fire protection systems, ensure top-notch performance, safety, and longevity.
Delta, a pioneer 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 labor costs.
Delta C-Series ESS’s peak shaving
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."
He adds, "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 labor 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.
Strategic decision-making and AI-driven optimization
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.
