BYD Battery-Box Premium LVS 8.0 (48V Low Voltage System)
Couldn't load pickup availability
The BYD Battery-Box Premium LVS 8.0 delivers 8 kWh of usable storage capacity right out of the box via two stacked LFP battery modules at 51.2 V nominal. The system includes a PDU (Power Distribution Unit), the Base and the integrated BMU (Battery Management Unit). Thanks to the patented internal plug system, both modules are stacked without additional wiring — further expandable to 24 kWh per tower or up to 256 kWh in parallel configuration. The high continuous discharge current of 130 A makes this system ideal for emergency backup and off-grid applications. Compatible with leading single-phase and three-phase inverters from GoodWe, Solis, Victron Energy and SMA.
- Capacity: 8.0 kWh usable (2 modules), expandable to 256 kWh (64 modules in parallel).
- Low Voltage 48V: Nominal voltage 51.2 V — maximum safety and wide inverter compatibility.
- Cobalt-free LFP technology: Maximum safety, long service life and high thermal stability.
- High discharge current: 130 A continuous / 180 A peak (5 s) — suitable for emergency power and off-grid use.
- IP55 and 10-year warranty: Reliable in demanding environments; round-trip efficiency ≥ 95%.
Scalable from 8 kWh to 256 kWh
The LVS series is designed for maximum flexibility. The LVS 8.0 starts with 2 modules and can easily be expanded — up to 6 modules (24 kWh) per tower, with multiple towers in parallel for larger installations up to 256 kWh. The system supports on-grid self-consumption optimisation, on-grid with backup function, and full off-grid operation. Communication is via CAN or RS485. Operating temperature: −10 °C to +50 °C (charge derating applies between −10 °C and +5 °C).
Not included: The BYD DC connection set for the LVS PDU (35–50 mm² connector set) — consisting of DC connectors, metal terminals, rubber cores, O-rings, claws and caps — and the battery cables to the inverter (2 × 35/50 mm² with M8 cable lugs, approx. 2 m) must be ordered separately.

Which inverters are compatible with the LVS 8.0?
The BYD Battery-Box Premium LVS 8.0 is a 48V Low-Voltage battery system communicating via CAN or RS485, compatible with leading single-phase and three-phase inverters, including:
- GoodWe (ES/EM/SBP series)
- Solis (RHI/S6 series)
- Victron Energy (MultiPlus / Quattro)
- SMA (Sunny Boy Storage / Tripower)
- Fronius, Studer and other certified brands
Always consult the current BYD compatibility list at bydbatterybox.com.
How far can I expand this system?
The LVS series is highly scalable. Starting from the LVS 8.0 (2 modules):
- Up to 6 modules (24 kWh) per tower — simply add modules without extra wiring.
- Up to 64 modules (256 kWh) by connecting multiple towers in parallel.
Each additional module increases both capacity and maximum discharge current, allowing the system to grow with your energy needs.
Does this battery help avoid feed-in costs?
Yes. By storing surplus solar energy in the LVS 8.0 and consuming it yourself later, you significantly increase your self-consumption rate, reducing feed-in to the grid and associated costs. Combined with a compatible inverter, the system also supports time-of-use (TOU) scheduling for maximum savings on your energy bill.
