The BSL 70kWh High-Voltage (HV) Lithium Battery Complete Set is a cabinetised, rack-based LFP storage system built for large homes, estates and commercial/industrial sites. Nominal 518.4V for direct pairing with HV hybrid inverters (e.g., Sunsynk/Deye/Solis/Livoltek HV classes). It arrives as a pre-engineered stack with master BMS, HV battery management unit and internal protection—ready for a qualified installer to commission. Supply only.
PRODUCT SPECS
- Total energy: 70kWh (nominal)
- Nominal voltage: 518.4V HV (typical operating window ±450–600V; installer to confirm per inverter profile)
- Nominal capacity: ≈135Ah class (energy ÷ voltage)
- Chemistry: LiFePOâ‚„ (LFP) with master/slave BMS architecture
- Configuration: HV cabinet with series-connected rack modules (typical builds use ~14 × 5.12kWh modules; final module count may vary by batch)
- Max continuous charge/discharge current: up to 100A class (site/inverter/profile dependent)
- Peak output: up to 1.5× short duration (installer to confirm limits)
- Round-trip efficiency: up to ≥95% (typical LFP)
- Cycle life: ≥6,000 cycles @ 80% DoD (reference conditions)
- Communications: CAN / RS485 with profiles for leading HV hybrid inverters (select the correct BSL ↔ inverter profile during commissioning)
- Protection & safety: integrated DC breaker/contactor, pre-charge, cell/pack balancing, OVP/UVP/OCP/OTP/UTP, short-circuit protection
- Thermal management: temperature monitoring with fan-assisted airflow (cabinet, model dependent)
- Enclosure: indoor cabinet (installer to provide ventilation/clearances; outdoor use requires a weatherproof plant room)
- Environmental: charge 0–50°C; discharge −20–60°C (typical); altitude ≤2,000m (derating may apply)
- Compliance: UN38.3 transit; typical cell/battery standards such as IEC 62619 (model/batch dependent)
- Warranty: 10-year manufacturer limited warranty (conditions apply; professional installation and correct settings required)
