Optimized & Industry-ready Solutions

20kwh 409V High Voltage Lithium Battery

The 20kWh system is a reliable and efficient solar energy solution. It consists of 4 battery modules, each with a capacity of 5.12kWh. Operating at a voltage range of 409.6V.

This 15kwh high voltage LiFePO4 battery system is suitable for homes, businesses, industries, agriculture, utility-scale applications, transportation, and renewable energy systems, seamlessly integrating with the grid to ensure power supply for critical loads.

Product Features

Reliable performance

We use stable lithium iron phosphate technology, ensuring high round-trip efficiency, a wide operating temperature range, and good durability.

Communication protocal

The 20kwh high voltage lithium battery supports RS485 and CAN communication ports. It connects with inverters or Power Conversion Systems (PCS) to convert direct current (DC) into alternating current (AC). If the system is unable to communicate with your inverter, please reach out to us. We can incorporate your inverter’s communication protocol into the system.

Long lifespan

The 20kwh high voltage lithium battery pack can complete 6,500 cycles, with a lifespan exceeding 10 years. Over long-term use, it not only covers its cost but can also yield greater returns.

10-Year Warranty

The yibai energy high voltage lithium battery consumes less energy, has high transmission efficiency, and comes with a 10-year after-sales warranty, giving you peace of mind.

Smart BMS

The BMS guarantees safety and availability, with strong compatibility, supporting three-phase off-grid inverters and hybrid inverters.

Stackable design

The stackable modular design allows for flexible capacity expansion, making it easy for you to disassemble, transport, install, test, and maintain.

Space utilization

With the same energy storage capacity, high-voltage energy storage systems may occupy less space because they can use fewer battery combinations in parallel.

High flexibility

Each module of the 20kWh battery bank has a capacity of 5.12kWh. By stacking multiple modules, you can achieve capacities of 10kWh, 20kWh, 30kWh, 40kWh, 50kWh, or 60kWh. We aim to help you easily adapt to changing load requirements. Additionally, the modular design and movable base make transportation, installation, and maintenance more convenient.
