- Sku: DYNEACC003
- Vendor: Dyness
Specifications
Product description
The Dyness 48V Lithium Battery Cable Kit brings together in a single package the power conductors, interconnection jumpers, and communication cable needed to link 51.2 V banks with compatible inverters. Specifically designed for LV (low voltage) systems, it simplifies assembly, reduces errors, and ensures BMS–inverter communication via CAN/RS485, guaranteeing safe and efficient charging and discharging.
Main features
- LV 48/51.2 V compatibility: suitable for Dyness low voltage modules (not HV).
- Complete set: DC cables (+/–), earth (PE), M8/M10 jumpers, and hardware.
- BMS communication: shielded RJ45 cable for CAN/RS485 with Dyness pinout.
- Indicative power cross-sections: 25/35/50 mm² depending on kW and distance.
- Typical admissible currents: ~120 A (25 mm²), ~150 A (35 mm²), ~180–200 A (50 mm²).
- Professional materials: tinned copper, PVC/XLPE insulation, and data shielding.
Advantages or benefits
- Faster installation: everything essential in one kit, fewer searches and errors.
- Electrical safety: appropriate cross-sections and correct terminals for Dyness terminals.
- Operational efficiency: proper BMS–inverter communication for optimal charge management.
- Long-term reliability: tinned conductors and professionally crimped connections.
- Fewer incidents: correct pinout and shielding to avoid noise on the CAN/RS485 bus.
Purpose or applications
Designed for residential and commercial solar systems at low voltage, where Dyness 48 V battery banks are integrated with hybrid inverters/chargers. Ideal for self-consumption with storage, backup, residential UPS, telecom, and small industrial applications that require native communication with the BMS.

Compatibilities
Compatible with Dyness LV 48 V/51.2 V banks and modules such as B4850, A48100/A48100-X, BX/BX5/BX51100, DL/DF 5.0, and PowerBox/PowerDepot systems in LV version. Not compatible with Dyness Tower (T7/T10/T14/T17/T21), PowerDepot H, or PowerCube HV.
BMS integration with inverters offering the Dyness 48 V profile via CAN/RS485 (e.g., Deye SUN LP1/LP3 LV, SolaX X1/X3 Hybrid LV, Solis RHI 48 V, Growatt SPH/SPA/SPF 48 V, GoodWe EM/ES 48 V, and Victron via GX device and CAN bus). Always select the “Dyness” profile in the inverter menu and observe the bus and maximum data cable length.
Recommendations: size the cross-section for ≤1–2% voltage drop; protect the positive pole with an ANL/MEGA fuse or DC circuit breaker; add a disconnect switch; use star connections on DC busbars; apply the tightening torque specified by the manufacturer and check temperatures during the first high-current charge/discharge cycles.
In summary, the Dyness 48V Lithium Battery Cable Kit is the practical and safe solution for wiring 51.2 V banks with reliable BMS communication, maximizing system performance and lifespan.
