EcoFlow DELTA Pro 3 Smart Extra Battery

DYNESS POWERBRICK 51V 280AH Features

High-Capacity & Reliable Energy Storage

• Large Capacity: Nominal energy of ~14.336 kWh with a 51.2 V / 280 Ah LiFePO₄ battery — ideal for significant residential or commercial storage needs.

• Advanced LiFePO₄ Chemistry: Stable and safe Lithium Iron Phosphate (LiFePO₄) cells offer superior thermal stability, safety, and longer life compared to traditional lead-acid batteries.

• High Depth of Discharge: Up to 95 % usable capacity — lets you use most of the battery’s stored energy without damaging cells.

• Long Cycle Life: Designed for ~8000+ cycles (~10 years) of operation, meaning years of reliable service with high efficiency.

Performance & Power

• Strong Charge/Discharge Currents:
  • Recommended charge/discharge current ~140 A (0.5C)
  • Max charge current ~200 A
  • Max discharge current ~200 A

• These high currents support powering large inverter loads in backup or off-grid systems.

• Continuous Discharge Power: Capable of supporting up to ~10 kW of continuous discharge in some configurations.

Smart Management & Connectivity

• Integrated Battery Management System (BMS): Provides protections against over-charge, over-discharge, over-current, over-temperature, and short circuits for safer long-term use.

• Communication Interfaces: CAN and RS485 communication protocols enable easy connection to inverters and monitoring systems.

• Built-in Wi-Fi Module: Some models include Wi-Fi for live system monitoring and OTA firmware updates via mobile apps.

Modular & Scalable

• Parallel Expansion: Supports up to 50 modules in parallel, letting you scale capacity from ~14.3 kWh up to ~716.8 kWh for larger systems without a hub.

• Ideal for residential storage, off-grid systems, commercial energy backup, or hybrid solar installations.

Safety & Certification

• Safety Certifications: Meets global safety standards including UN38.3, CE, and IEC62619.

• Optional Fire Protection System: Some versions support an aerosol fire extinguishing module for enhanced protection in harsh environments.

• Protection Rating: Typically IP20 for indoor battery installations.

Design & Installation

• Robust, Compact Build: Designed for floor-standing residential energy storage.

• Easy Installation: Smaller footprint and lighter weight profile compared to older battery designs make installation easier.

• Wide Operating Temperature: Operates from 0 °C to 55 °C for charging and –20 °C to 55 °C for discharging, accommodating various climates.

Good For

• Solar hybrid systems (on-grid/off-grid) with compatible inverters (e.g., SMA, Victron, Solis, GoodWe, Deye, Growatt).

• Home backup power during outages.

• Commercial energy storage and demand shifting.

• Scalable energy solutions where future expansion is needed.
