Features of 6.5kW All-in-One Energy Storage System 51.2V 100Ah
Flexible Modular Configuration
You can configure the system with 2–4 battery modules to match your project requirements, with capacities ranging from 10.24kWh to 20.48kWh.
- 2 modules: 10.24kWh
- 3 modules: 15.36kWh
- 4 modules: 20.48kWh

Easy Installation & Wiring
The battery modules use a plug-in connection design, allowing them to connect directly without complex wiring between modules. Side-mounted ports provide easy access for external cables, while built-in handles make the modules easier to move and install on site.

Integrated 6.5kW Hybrid Inverter
The system integrates a 6.5kW hybrid inverter with up to 6500W of PV input and a PV input voltage range of 60–500VDC. With a peak output of 10kVA, it can handle the startup power requirements of loads such as air conditioners and water pumps. Dual AC outputs allow essential and non-essential loads to be managed separately, while a 10ms UPS transfer time provides fast backup power during grid outages.
Grade-A LiFePO4 Cells & Smart BMS Protection
The battery uses Grade-A LiFePO4 cells with a cycle life of 6,500+ cycles and a design life of over 10 years, helping reduce replacement frequency and long-term operating costs. Each battery module is equipped with an independent BMS that continuously monitors voltage, current, and temperature and provides protection against overcharge, over-discharge, overcurrent, short circuits, and abnormal temperatures. A 3.5-inch LCD screen allows installers to view operating data and adjust system settings for easier installation, commissioning, and maintenance.

CAN/RS485 Communication & Remote Monitoring
The system is equipped with CAN, RS485, and RS232 communication interfaces, along with built-in Wi-Fi. Users and service teams can view operating data, monitor system status, and perform remote diagnostics via an app or web platform.
Applications
- Alimentation résidentielle: Keeps essential household loads such as refrigerators, lighting, air conditioners, and communication equipment running during grid outages.
- Small Commercial & Workshop Applications: Supports daily energy use and backup power needs for shops, offices, farms, and small workshops.
- Off-Grid & Remote Areas: Works with solar PV and generators to provide independent power where grid access is unavailable or unreliable.
Certifications & Documentation
Delong provides relevant certifications and documentation for this 6.5kW all-in-one energy storage system, including CE, IEC, KC, MSDS, and UN38.3, to support transportation, installation, and compliance requirements in different markets.
