High-Performance Energy Storage Solution
The CSSUN LPW48V200H-sc stands out in residential energy storage with its 51.2V 200Ah configuration, delivering 10.24kWh capacity through automotive-grade LiFePO4 cells. Unlike traditional lead-acid batteries that resemble gas-guzzling cars, this unit operates like a hybrid vehicle - efficient, durable, and low-maintenance.
Key Technical Specifications
- Nominal Voltage: 51.2V DC
- Energy Capacity: 10.24kWh
- Cycle Life: 6,000+ cycles at 80% DoD
- Operating Temperature: -20°C to 55°C
- Wall-mounted design: 750×550×250mm footprint
Smart Battery Management System (BMS)
Equipped with a 3-level protection BMS that monitors cell voltage like a nervous system tracking vital signs. The system prevents:
- Overcharge (＞58.4V cutoff)
- Deep discharge (＜40V protection)
- Thermal runaway (＞65°C shutdown)
Real-World Performance Data
In field tests across 20 Guangdong households, the battery maintained 94.7% round-trip efficiency after 1,500 cycles. Compare this to the industry average of 92% for similar LiFePO4 systems.
Solar Integration Capabilities
Designed for seamless integration with 2-5kW solar arrays. The modular design allows parallel connection of up to 16 units (163.84kWh total capacity). Compatible with major hybrid inverters including:
- Huawei SUN2000-5KTL-L1
- Growatt MIN 5000TL-X
- Deye SUN-5K-SG01LP1
Safety Certifications
Certified to UL1973, IEC62619, and UN38.3 standards - the "triple crown" of battery safety. The UL certification process alone involves 21 separate abuse tests including nail penetration and thermal shock evaluations.
Economic Analysis
At current pricing (CN¥4,345/unit for bulk orders), the levelized cost of storage (LCOS) calculates to:
- CN¥0.42/kWh over 10-year lifespan
- 56% lower than lead-acid alternatives
- 23% savings versus comparable LiFePO4 systems
The wall-mounted installation reduces floor space requirements by 40% compared to rack-mounted alternatives. Maintenance needs? About as frequent as watering a cactus - the self-balancing BMS requires only annual visual inspections.
Technical Support & Warranty
Backed by a 7-year performance guarantee covering:
- 80% capacity retention after 3,500 cycles
- Free replacement for BMS failures
- 48-hour emergency response service
Future-Proof Design Features
Incorporates RS485/CAN communication ports for smart grid integration. The battery's firmware supports OTA updates, allowing compatibility with emerging standards like IEEE 2030.5 for demand response programs.
