5-30KWH Stacked Lithium Batteries
Capacity & Power Output: With a nominal voltage of 48V (typically 51.2V for LiFePO4 chemistry) and a 15kWh capacity (equivalent to ~312.5Ah at 48V), this battery provides ample energy to power:
A small home's essential appliances (fridge, lights, TV) for 1–2 days
A 5kW solar system's surplus energy storage
Commercial equipment (security systems, small machinery) during grid outages.
It supports continuous discharge currents of up to 100A (4.8kW) and peak surges of 200A (9.6kW), making it compatible with 48V inverters, charge controllers, and grid-tie systems.
Stacked Modular Design: Unlike single-unit batteries, it features a stacked configuration-multiple 2–5kWh lithium modules (typically LiFePO4) connected in series/parallel to reach 15kWh. This design offers:
Scalability: Users can start with a smaller capacity (e.g., 5kWh) and add modules later to reach 15kWh, adapting to growing energy needs.
Easy Maintenance: Individual modules can be replaced if faulty, reducing repair costs compared to replacing an entire monolithic battery.
Space Efficiency: Stacked vertically or horizontally, it fits in compact spaces (e.g., utility rooms, basements) with a footprint of ~0.5–1㎡ (depending on module count).
Advanced BMS Integration: The built-in 48V Battery Management System (BMS) is a critical feature, providing:
Cell Balancing: Ensures uniform charging/discharging across all modules, preventing overvoltage or undervoltage in individual cells.
Comprehensive Protection: Guards against overcharging, over-discharging, short circuits, overcurrent, and thermal runaway (with temperature sensors and cooling fans).
Data Monitoring: Tracks state of charge (SoC), cycle count, voltage, and temperature via a digital display or app, enabling proactive maintenance.
Grid/Inverter Compatibility: Communicates with 48V inverters to optimize charging (e.g., prioritizing solar input) and prevent grid overload.
