Couldn't load pickup availability
The BYD Battery-Box Premium LVS 4.0 sets the standard for safe and flexible 48V (Low Voltage) energy storage. This starter package consists of one powerful 4 kWh battery module and the essential control unit (PDU/Base). Thanks to the patented internal plug connection, you can easily stack modules without complex wiring. This system is the premier choice for both on-grid optimization and robust off-grid applications.
- Capacity: 4.0 kWh (Starting capacity), expandable up to 256 kWh.
- Low Voltage: 48V (51.2V Nominal) for maximum safety.
- Chemistry: Cobalt-free Lithium Iron Phosphate (LFP) technology.
- Robust: IP55 enclosure, suitable for demanding environments.
Maximum Flexibility & Off-Grid Power
The LVS series is renowned for its immense scalability. You start with this 4.0 kWh set and can easily add modules later (up to 24 kWh in one tower) or even connect towers in parallel for commercial capacities. The system supports high discharge currents (65A continuous per module), making it perfect for emergency power supplies and off-grid islanding in combination with brands like Victron Energy.
