Project Overview

The client required a high-capacity battery system capable of supporting long-duration power outages and reducing dependence on the grid. After evaluating multiple options, they selected our RND-H60 cabinet energy storage system due to its robust performance, modular design, and long cycle life.

This solution is designed for residential and small commercial applications where stable energy supply and high safety standards are critical.

System Configuration

The installed system features a lithium iron phosphate (LFP) battery pack with a 128S1P configuration, delivering high energy density and long service life. The cabinet integrates battery modules, BMS, and communication interfaces into a single compact unit, simplifying installation and maintenance.

Key technical specifications:

  • Battery Type: Lithium Iron Phosphate (LFP)
  • Nominal Capacity: 150Ah
  • Nominal Voltage: 409.6V
  • Total Energy: 61.44kWh
  • Rated Output Power: 30kW / 33kVA
  • Cycle Life: ≥ 6500 cycles
  • Communication: LAN / CAN / RS485
  • Protection Level: IP54 (cabinet), IP66 (battery modules)

Reliable Performance in Harsh Environments

The system is engineered to operate in demanding conditions, ensuring stable performance across a wide temperature range:

  • Charging temperature: 0°C to 55°C
  • Discharging temperature: -20°C to 55°C
  • Storage temperature: -20°C to 45°C

This makes the product suitable for diverse climates, including regions with extreme seasonal temperature changes.

Safety and Structural Design

Safety is one of the core priorities in the design of this energy storage cabinet. The system uses high-stability LFP cells, which offer better thermal stability and lower risk of thermal runaway compared to other lithium battery chemistries.

The cabinet adopts a sealed and dust-resistant structure with high protection ratings, ensuring reliable operation in both indoor and semi-outdoor installations. The modular structure also allows easier transportation, installation, and future capacity upgrades.

Installation and Deployment

The system was delivered as a fully assembled cabinet with dimensions of 1020 × 730 × 2000 mm, allowing for quick on-site installation. With integrated communication ports and a pre-configured battery management system, the product was successfully commissioned in a short timeframe, minimizing disruption to the household’s daily electricity usage.

Customer Benefits

After installation, the household gained several key advantages:

  • Continuous power supply during grid outages
  • Reduced electricity costs through energy storage and peak shaving
  • Improved energy independence and stability
  • Long lifecycle with minimal maintenance requirements

The client reported stable performance and smooth integration with their existing power system.

Conclusion

This project demonstrates how large-capacity residential energy storage systems are becoming an essential component of modern homes. With high safety standards, long service life, and strong environmental adaptability, the RND-H60 household energy storage system provides a dependable and future-ready solution for residential backup and energy management.

As demand for clean and reliable energy continues to grow, we remain committed to delivering advanced, high-performance storage solutions tailored to global residential and commercial markets.
