FAQ
GE-F128: Delivers 128.61 kWh nominal energy (approx. 112.5 kWh usable) operating across a voltage range of 320V to 467V DC.
GE-F256: Delivers 257.2 kWh nominal energy operating across a high-voltage range of 640V to 934.4V DC.
DC Expansion (Batteries): You can connect up to 10 battery cabinets in parallel on the DC side to scale up total energy capacity.
AC Expansion (Inverters): Up to 10 inverter units can be run in parallel on the AC side to scale total power output.
User and installer discussions emphasize that Deye’s commercial cabinets utilize a multi-layered safety architecture (often referred to as their Six-Dimensional Safety Design):
Active Protection: Built-in aerosol fire suppression systems, active exhaust, and combustible gas/smoke/temperature sensors.
Thermal Isolation: Optimized thermal management designed to keep cell temperature variances to a minimum (≤ 6℃), preventing thermal runaway propagation.
Structural Durability: High-strength outdoor cabinet ratings (typically IP54/IP65 equivalent protection) with hour-level fire resistance and heavy-duty structural latch designs.
The systems support operation in demanding climates with no power derating up to 45°C ambient temperature. They use high-performance LiFePO₄ prismatic cells rated for ≥ 8,000 charge-discharge cycles, making them suitable for heavy daily cycling (arbitrage and peak shaving).
Deye utilizes a 6-Dimensional Safety Architecture (D1–D6):
D1: Electrical Isolation
D2: Fire/Smoke Detection & CO Gas Sensors
D3: Active Exhaust Ventilation
D4: Explosion Venting Ports
D5: Built-in Aerosol & Water Fire Interface Suppression
D6: Pack-level Thermal Isolation & Hour-Level Fire Resistance
Yes. The system topology allows for direct PV + BESS + DG (Diesel Generator) integration.The Deye hybrid inverter can automatically signal generator auto-start/stop based on battery State of Charge (SOC) or peak demand thresholds.
Backup operation depends on the selected inverter or PCS, system controls, and electrical configuration. The battery cabinet alone does not guarantee backup power. Before purchasing, confirm islanding capability, supported backup loads, transfer arrangements, black-start requirements, and the maximum power available during an outage.
The relevant Deye configurations list IP55 cabinet protection. However, outdoor suitability also depends on installation instructions, ambient temperature, drainage, access, ventilation, and local electrical and fire codes. Verify the protection rating and environmental limits for the exact model and regional version.
