Outdoor IP54 Commercial Energy Storage Cabinet – 50kW / 50kWh

The GCB-E50 is a fully integrated outdoor energy storage cabinet designed for commercial and light industrial applications requiring reliable performance in challenging environments. With 50kW rated power and 50kWh usable energy, this all-in-one system features IP54 ingress protection, ensuring safe operation in outdoor settings with protection against dust and water splashes. The operating temperature range of -20°C to 50°C and integrated air cooling (with refrigeration, ventilation, and heating) maintain stable performance across diverse climates.

Built with LFP (lithium iron phosphate) battery cells for enhanced safety and long cycle life, the cabinet incorporates an integrated fire protection system for added security. System efficiency reaches ≥90%, with RS485 and CAN communication interfaces enabling seamless integration with energy management systems and inverters. The compact footprint (780×640×2000 mm) and 625 kg weight make it suitable for space-constrained commercial sites.

Whether for peak shaving, backup power, or renewable energy self-consumption optimization, the GCB-E50 delivers a robust, weather-resistant, and ready-to-deploy commercial energy storage solution.

Product Features

01
Advanced Battery Cell Technology

Utilizing Grade A LFP100Ah lithium iron phosphate battery cells with a 10-module series configuration (10S1P), rated voltage 512V, and total energy of 50kWh. The cells undergo strict voltage sorting with a voltage difference of ≤5mV and high internal resistance consistency, achieving a cycle life of over 6,000 cycles, ideal for light commercial and industrial applications.
02
Highly Integrated All-in-One Design

The battery cluster, 50kW PCS, BMS, EMS, and power distribution units are highly integrated into a compact 780*640*2000mm cabinet. A single cabinet operates independently without the need for complex external systems, making it particularly suitable for space-constrained locations such as street shops and small farms.
03
Intelligent Air Cooling Thermal Management System

Equipped with an intelligent forced-air cooling system integrating cooling, ventilation, and heating functions. It precisely controls the battery cell operating temperature, ensuring stable operation in ambient temperatures ranging from -20°C to 50°C, effectively mitigating thermal runaway risks.

What commercial scenarios can a 50kWh capacity support? Is one cabinet sufficient for typical needs?

A 50kWh/50kW system is well-suited for: Peak shaving: Reducing demand charges for businesses with moderate peak loads (e.g., offices, retail stores, small factories). Backup power: Providing 1–2 hours of backup for critical loads (lighting, security, refrigeration) during outages. Solar self-consumption: Storing excess PV generation for a 50–100 kWp commercial solar system. For larger applications, multiple GCB-E50 cabinets can be paralleled to increase capacity and power. The modular design allows you to start with one cabinet and scale up as energy needs grow.
