WeCo 5K3-XP 5.3 KWh 51.2V Lithium Battery | Dual Voltage Design

The WeCo 5K3-XP 5.3 kWh 51.2V Lithium Battery is a dual-voltage (low and high voltage) lithium iron phosphate (LiFePO4, LFP) battery module designed for residential, commercial, and industrial energy storage applications. Key Features of the WeCo 5K3-XP 5.3 kWh 51.2V Lithium BatteryBattery Chemistry and Safety:Lithium Iron Phosphate (LFP): Cobalt-free, offering high safety, thermal stability, and a long lifespan with minimal risk of thermal runaway. Cycle Life: Rated for over 7,800 cycles at 100% depth of discharge (DOD), or over 10,000 cycles at 80% DOD, ensuring long-term reliability. Certifications: Meets safety standards including IEC62619, CE, CEC, and UN38.3, suitable for various markets. Capacity and Scalability:Usable Energy: 5.3 kWh per module (5.37 kWh nominal, 100 Ah), with 100% DOD for maximum usable capacity. Scalable Design: Low Voltage (LV): Up to 15 modules in parallel without a hub (79.5 kWh), or up to 100 modules with a WeCo LV Expansion Hub (530 kWh). High Voltage (HV): Up to 16 modules in series per HV cluster (85.92 kWh), or up to 144 modules with multiple clusters (768 kWh) using a WeCo HV Box. Modular System: Expandable by adding modules, with compatibility for previous WeCo 5K3 models for seamless upgrades. Electrical Specifications:Nominal Voltage: 51.2V, compatible with 48V systems like the Victron Quattro. Operating Voltage Range: 46.5–58.4V (LV) or 80/200–750V (HV with BMU). Charge/Discharge Current: Continuous: 100A (1C, ~5,500W), allowing full charge in ~1 hour. Peak: 200A (2C, ~10,000W) for 30 seconds, ideal for high inrush loads. Efficiency: High charge/discharge efficiency due to active cell balancing. Dual Voltage Capability:Unique Dual BMS: Patented dual Battery Management System (BMS) supports both low-voltage (48V) and high-voltage (80–750V) configurations with dual connection ports (CAN A for LV, CAN B for HV). Requires a WeCo BMU for HV operation. Applications: Suitable for low-voltage residential systems (e.g., with Victron inverters) or high-voltage commercial/industrial setups. Battery Management System (BMS):Advanced BMS: Features real-time monitoring of cell parameters (voltage, temperature, state of charge) with active and passive equalization for optimal performance. Active Equalizer: Transfers energy between cells (up to 10A current compensation), ensuring constant balancing, higher efficiency, and extended battery life compared to passive systems. Communication Ports: Supports CAN, RS232, RS485, WiFi, and Bluetooth for integration with inverters and monitoring systems. Mobile App: WeCo Batteries app (iOS/Android) enables remote monitoring, protocol changes, firmware updates, and diagnostics via WiFi (5G-compatible) or Bluetooth. Physical Specifications:Dimensions: 492mm (L) x 580mm (W) x 170mm (H) or 463mm (D) x 580mm (W) x 155mm (H), depending on source. Weight: 54–57.3 kg per module. Mounting Options: Wall-mounted (single module), stackable (2+ modules), or rack-mounted in standard 19" cabinets, with brackets and LV cables included. No external cabinet required. Protection Rating: IP20, suitable for indoor use. Compatibility:Universal Compatibility: Works with leading inverters including Victron, Goodwe, Voltronic Axpert, Studer, SMA, Solis, Deye, Schneider, Sofar Solar, Growatt, and others via CAN/RS485 communication. Can also operate without communication by programming manufacturer-recommended charge values. Integration with Victron Quattro 48/10000: Communicates via CAN (500 kbit/s) through a GX device (e.g., Cerbo GX, firmware v2.52+), supporting charge/discharge limits and error reporting. Performance and Environmental Resilience:Extreme Temperature Operation: Discharge: -20°C to +65°C. Charge: -7°C to +55°C (some sources cite -10°C to +55°C). Certified for desert environments by telecom operators. High Energy Density: Compact design with robust storage capacity. Applications: Ideal for on-grid, off-grid, and hybrid systems, including solar self-consumption, emergency backup, and industrial storage. Installation and Maintenance:Plug-and-Play: Includes mounting brackets, LV cables, and parallel communication cables for easy setup. Accessories: First-time LV setups require a WeCo power cable kit and communication cable. HV setups require a WeCo BMU. Expansion for LV systems needs parallel terminals; HV systems may need a BMU and hub. Maintenance: BMS diagnostics and modular design simplify troubleshooting and upgrades. Warranty:Standard Warranty: 10 years, covering performance and defects, subject to manufacturer terms.
