CTECHI ESS50KW/112KWh Split-Type Commercial & Industrial BESS Solar Battery Energy Storage System

Product Introduction

The CTECHI ESS50KW/112KWh split-type energy storage system delivers an ideal balance of capacity and power for mid-tier commercial and industrial applications. Engineered around the 314Ah LFP cell platform with 7 packs in a 16S series configuration, the system achieves a nominal voltage of 358.4V and a total energy capacity of 112kWh — offering approximately 72% more storage than the entry-level 65kWh model while maintaining the same split-cabinet deployment advantages. The 50kW hybrid inverter bridges medium-power loads with high efficiency, making it suitable for facilities with 50–150 kVA transformer capacity. Air-cooled thermal management, IP54 ingress protection, and dual RS485/CAN communication channels ensure reliable operation across diverse environmental conditions. Whether deployed for demand charge management, solar self-consumption maximization, or critical load backup, the ESS50KW/112KWh provides a scalable, cost-effective path to energy resilience.

Optimized Split-Cabinet Configuration

Building on a modular split-type architecture, the ESS50KW/112KWh physically separates the battery cabinet, which houses seven 16S1P packs, from the 50kW hybrid inverter. This flexible design allows the cabinets to be positioned up to 5 meters apart, making it an ideal choice for retrofitting commercial buildings with irregular floor plans or structural constraints like columns. Furthermore, the battery cabinet features a front-access maintenance design that eliminates the need for rear clearance, providing a significant spatial advantage for wall-adjacent or tight-space installations.

Scalable 358.4V High-Voltage DC Platform

Operating at a nominal 358.4V, the system strikes an optimized balance between high conversion efficiency and operational safety. By utilizing a higher voltage platform, it effectively reduces conduction losses on DC cabling compared to lower-voltage alternatives, while remaining comfortably within Low Voltage Directive (LVD) thresholds for simplified regulatory compliance. This 7-pack series configuration supports a wide voltage range of 302.4V to 408.8V, delivering a nominal capacity of 112.5kWh with 101.3kWh of usable energy at 90% DoD, capable of sustaining a maximum continuous power output of 50kW.

Advanced Thermal Management for High-Duty Cycles

To ensure reliable performance during high-duty cycles, the system employs an intelligent air-cooling system equipped with variable-speed fans and N+1 redundancy. This thermal strategy is driven by a network of 42 specialized sensors monitoring temperatures at the cell, pack, and cabinet levels to maintain a cell temperature deviation of less than 5°C. The system also includes ambient temperature compensation for smart current derating, anti-condensation heaters for reliable cold-starts below 0°C, and IP5X-rated dust filtration to ensure long-term stability in diverse environmental conditions.

Target Application Profiles

The 50kW/112kWh configuration is specifically optimized for medium-sized commercial environments, ranging from retail and office buildings up to 5,000 m² to energy-intensive facilities like cold storage and refrigerated warehouses. It serves as an excellent solution for agricultural climate control, small manufacturing lines with 30-50kW average loads, and multi-tenant commercial parks seeking shared storage for demand charge reduction. Additionally, it is a powerful tool for diesel generator hybridization, capable of reducing generator runtime and fuel consumption by 60% to 80%.
