2x15kwh 51.2V 300Ah Lifepo4 Battery Pack With 10kw Inverter SPECIAL OFFER

Special offer for Inverter 10KW and 2x 15 KW TOTAL 30KW Batteries. ALL in ONE

Delong’s latest 15kWh all in one battery system is divided into three components: three 15kWh battery modules, a 10kW inverter, and a wheeled base. This system plays a crucial role in solar power setups. It also allows for real-time remote control via an app or website.

Quality of A-grade Cells

Each battery module is built with brand-new A-grade lithium iron phosphate (LiFePO4) cells. These cells operate across a broad temperature range (-10°C to 60°C). They also provide the battery pack with a long cycle life of over 6,500 cycles.

Intelligent BMS for Enhanced Safety

Each battery pack is equipped with a highly secure intelligent BMS. It provides comprehensive protection for the 45kWh battery, preventing risks like overheating, overcurrent, overvoltage, and short circuits. The BMS supports RS485 and RS232 interfaces, allowing for easy data transfer between the battery and other devices.

Stable Power Output

Each battery pack consists of 16 highly consistent cells connected in series. They offer excellent stability, ensuring a steady voltage output during connection with devices.

Adjustable Flexibility

The 51.2V 900Ah lifepo4 battery pack stores 45kWh of energy. During use, you can reduce the number of parallel-connected batteries to achieve 15kWh or 30kWh as needed.

15-45kwh All In One Lithium Battery

Plug-and-Play Experience

The inverter is positioned at the top, connected directly to the lithium iron phosphate battery below. This integrated design eliminates compatibility concerns. The battery requires only a simple DIY connection and is ready for use within minutes.

Real-Time Data Display

Each battery module is equipped with an LED screen, allowing you to monitor the battery’s operating status in real-time.

Movable Battery

The base of the battery pack is equipped with swivel casters that rotate 360 degrees. These wheels allow you to move the 354kg battery to locations where power is needed, making it a labor-saving design.

Compact and Powerful

Each battery module measures 690*590*258/388 mm, just one-third the size of a lead-acid battery. Its stackable design minimizes space requirements while delivering impressive performance.

10-Year Warranty

We offer a ten-year service guarantee for the 45 kWh battery. If any issues arise during this period, please feel free to contact us. We’ll provide technical support or handle returns and exchanges as needed.

Wide Applications

The Delong 45 kWh battery features M8 terminals, a durable metal casing, and sturdy casters. It’s suitable for solar energy storage, household energy systems, telecom stations, medical facilities, and commercial setups. The 45 kWh solar battery stores energy during the day and releases it at night, serving as a backup or uninterrupted power source to ensure stable power supply. For instance, it can charge electric vehicles, helping you save energy and reduce electricity costs.

The 45 kWh battery is equipped with a 10 kW inverter, converting DC to AC power. With a peak efficiency above 93%, the inverter minimizes your energy losses. It accepts an input voltage range of 185V to 280VAC, making it compatible with various grid voltages. The 10 kW inverter has a maximum input current of 40A and an output voltage of 220VAC. It supports RS485, CAN, and WIFI communication interfaces.

If you already have an inverter, you can simply opt for the standalone 45 kWh lithium battery, which is also a viable option. We also offer a 45 kWh battery in a rack mount. Both versions come in durable metal casings with high-quality construction. You can refer to the data table below to select the battery that best suits your needs.
