🔋 Dyness DL 2.5 Battery
Brand: Dyness
Model: DL 2.5
Type: Lithium-Ion (LiFePO₄) Rechargeable Battery Module
Application: Residential and light commercial energy storage systems, solar + backup, hybrid inverters
⚡ Key Features
• 2.5 kWh nominal energy capacity — ideal for small residential systems, emergency backup, and off-grid applications
• LiFePO₄ (Lithium Iron Phosphate) chemistry — high safety, thermal stability, and long cycle life
• Integrated BMS (Battery Management System) — protects against over-charge, over-discharge, over-current, over-temperature, and cell imbalance
• Compact & stackable design — modular format allows multiple units for scalable storage banks
• High cycle life — built for frequent daily cycling without performance degradation
• Compatible with low-voltage hybrid inverters — works well with Dyness, Sunsynk, Deye, and other 48–51.2 V inverter systems (verify compatibility)
• Low self-discharge rate — retains charge efficiently during idle periods
• Indoor rated installation — suitable for battery closets, utility rooms, and energy storage cabinets
