Dyness DL2.5 2.56 kWh Lithium Battery (24V)

The Dyness DL2.5 is a high-performance 2.56 kWh rechargeable battery module, designed especially for residential and light commercial solar energy systems. Built with LiFePO₄ (lithium iron phosphate) chemistry, it offers excellent safety, thermal stability, and a long cycle life. This modular battery is ideal for pairing with hybrid or off-grid inverters to provide reliable energy storage and backup during power outages or nighttime hours.

The DL2.5 is part of the Dyness low-voltage energy storage line and supports up to 16 units in parallel, allowing system expansion from 2.56 kWh up to 40.96 kWh total capacity.Because of this scalability, it’s suitable for homes wanting to start small and grow later.

🔋 Key Features & Specifications

• Capacity: 2.56 kWh (nominal)

• Voltage: 24 V (100 Ah)

• Chemistry: LiFePO₄ – safer and more stable than many alternatives

• Scalability: Supports up to 16 units in parallel to reach 40.96 kWh total

• Discharge Rate: 1.3C (i.e. can discharge at a rate up to 1.3× its capacity)

• Battery Management System (BMS): Integrated to control overcharge, over-discharge, short circuits, and cell balancing

• Cycle Life: Typically thousands of cycles (as is common for LiFePO₄)

• Operating Temperature Range & Safety Protections: Designed for safe operations across typical residential conditions

• Parallel Operation: Up to 16 units for larger capacity systems

🏠 Applications & Uses

• Residential Solar Systems: Powers lighting, fans, refrigerators, small electronics during power cuts.

• Small Commercial Settings: Off-grid shops, remote offices, or backup for critical loads.

• Hybrid Solar Systems: Used alongside solar inverters to store excess generation and dispatch when needed.

• Portable or Modular Energy Storage: Because it’s scalable, you can start with one module and add more later as demand increases.

✅ Benefits & Advantages

1. Safety & Durability

Thanks to LiFePO₄ chemistry, the DL2.5 has strong thermal stability and lower risk of combustion compared to some other lithium types. The built-in BMS ensures protection against overcharge, deep discharge, cell imbalance, and overcurrent.

2. Scalable Design

You can expand your battery bank easily. Starting with one module gives you 2.56 kWh, and as your energy needs grow, you can add up to 16 in parallel for nearly 41 kWh of capacity.

3. High Discharge Capability

With a 1.3C discharge rate, the DL2.5 can supply burst loads when needed, making it practical for appliances that surge in power consumption.

4. Long Life & Lower Maintenance

These batteries can endure thousands of charge/discharge cycles, offering years of service without frequent replacements or heavy maintenance.

5. Efficient Energy Use

With low internal losses and efficient BMS control, energy is stored and retrieved with minimal loss, making it a smart choice to maximize your solar investment.

⚠️ Things to Check / Best Practices

• Compatibility: Make sure your inverter supports 24 V battery input and is compatible with LiFePO₄ battery chemistry.

• Parallel Balancing: When connecting multiple units, ensure proper cables and balancing to avoid uneven cell usage.

• Environment Conditions: Install in a shaded, cool, ventilated location to extend battery life.

• Warranty / After-Sales Support: Check with supplier (SolarSwitch.pk) for warranty terms, support, and quality assurance.

• Proper Sizing: 2.56 kWh is moderate capacity — suitable for essential loads. For larger load demands, plan parallel expansion or use in combination with larger modules.

📈 Example Use Case

Imagine a typical household where evening usage includes lights, fans, a refrigerator, and a few small electronics totaling ~500 W load. The DL2.5 2.56 kWh battery can supply:

• 500 W × 4 hours = 2,000 Wh (2 kWh) — it would cover this comfortably with buffer.

• For higher loads, adding multiple DL2.5 modules can scale capacity to match demand.

In a hybrid solar-inverter setup, during daylight hours solar panels recharge this battery. At night or during outages, the inverter draws from the DL2.5 to power your loads. Call Now
