What is the BYD collection?

The BYD collection groups Battery-Box Premium storage systems based on lithium iron phosphate (LFP) and its control ecosystem (BMU/BCU/PDU). It includes low voltage lines (48 V: LVS and LVL) and high voltage lines (HVS and HVM), all modular and expandable to suit homes, businesses, and light industry.

Advantages and limitations

• Safety and lifespan: LFP chemistry without cobalt, high thermal stability, and long durability.
• True scalability: stackable modules (LVS 4 kWh; HVS 2.56 kWh; HVM 2.76 kWh; LVL 15.4 kWh per unit).
• Integration: CAN/RS485 communications and compatibility with leading hybrid inverters.
• Protection and installation: IP55 rating and official electronics (BMU/BCU/PDU) for management and safety.
• Limitations: correctly choose LV vs HV according to the inverter; respect minimum/maximum module configurations per tower.

Applications

• Residential: self-consumption with 48 V (LVS/LVL) or HV (HVS/HVM) depending on the inverter.
• Light commercial: HV banks with higher efficiency and backup power.
• Systems with backup (EPS/Backup) and peak-shaving in time-of-use tariffs.

How to choose

• Voltage: 48 V (LVS/LVL) for broad compatibility and retrofit; HV (HVS/HVM) for three-phase and higher performance.
• Capacity: size based on useful daily consumption and required EPS power; expand by modules.
• Electronics: BMU/BCU/PDU required to start towers and manage communications.
• Environment: check IP rating and ventilated location; respect clearances and grounding.

Best practices

• Check inverter and voltage compatibility (48 V vs HV) before choosing the series.
• Size by usable energy (DoD) and peak power of critical loads.
• Use appropriate DC wiring and protections (fuses, disconnectors, SPD) and ensure proper ventilation.
• Plan for future expansions by leaving capacity and physical space margin.

Comparisons and selection within the catalog

• LVS / LVL (48 V): maximum compatibility and flexibility in residential.
• HVS / HVM (HV): higher efficiency and power with three-phase inverters.
• Accessories: BMU, BCU, PDU, and specific wiring to start or expand towers.

Related accessories

• System management: BMU/BCU and PDU distribution.
• Official structure and wiring for stacking and safe connection.
• DC/AC protections in DC Electrical Protections and AC Electrical Protections.

With its LFP technology and modular architecture, BYD enables the creation of safe, efficient, and scalable battery banks, ready to integrate with hybrid inverters and maximize solar self-consumption.
