Huawei LUNA2000-14-S1 - 14kWh storage package

🔋 Main Parameters

Type: High-voltage modular energy storage system based on lithium iron phosphate (LiFePO₄) cells—a safe, durable chemistry with a high level of thermal stability.
Usable capacity: ≈ 13.8 kWh (2 modules of ~6.9 kWh)—energy available for charging/discharging.
Maximum charging/discharging power: ≈ 7.0 kW (within a single module)—sufficient power for household loads.

🔌 Electrical Specifications

Operating voltage range:
• Single-phase system: ~350–560 VDC
• Three-phase system: ~600–980 VDC

Communication/Interfaces: RS485 / FE / CAN—for communication with inverters and the FusionSolar monitoring system.

🛡 Reliability and Safety

Casing protection rating: IP66 — suitable for outdoor use with protection from dust and moisture.

Cell type: LiFePO₄ — durable and safe to operate.

Mounting: Standard floor-standing, wall-mountable.

Operating temperature: -20°C to +55°C — wide operating range for various climates.

Noise: Quiet operation due to passive cooling (natural convection).

📏 Dimensions and Weight

Dimensions (W × D × H): ~590 × 255 × 870 mm — compact housing, takes up little space.

Weight: approximately 148 kg (all equipment including rack/mounting kit).

⚙️ Functionality and Expandability

✔️ Modular Architecture: Thanks to the modular design, capacity can be expanded by adding a third battery bank up to ~20.7 kWh in a single tower, or even more through parallel connection up to ~82.8 kWh per inverter in a multi-bank configuration.
✔️ Full Depth of Discharge (100% DoD): Nearly all capacity can be utilized for maximum self-sufficiency.
✔️ Compatibility: Suitable for a wide range of Huawei SUN2000 family inverters (MAP0, M1, MB0, etc.).
✔️ Integration with FusionSolar monitoring: Allows you to monitor battery status, SOC, cycles, and manage the system via an app.
