3. Intelligent lithium battery management system: With RS485 communication, you can monitor the battery status at any time and set protection parameters such as charge and discharge according to customers'requirements.

4. Warning function: Warning functions such as overcharge, overdischarge, overcurrent, high temperature and low temperature can greatly reduce the potential safety hazard.

5. Balancing: Automatic collection of battery single series voltage, pressure difference up to 30MV (can be set), automatic start equalization function.

Q: What is your Quality Assurance and Technical Support Policy?
A: We provide reliable, high-quality products. Each battery is carefully designed and tested to meet top standards, minimizing maintenance needs and potential risks. This commitment to quality ensures your energy storage solution performs flawlessly, delivering optimal efficiency.
For support, please contact an authorized dealer in your area for fast assistance and replacements. In areas without a dealer, we offer remote support via Zoho Lens, where our experts use AR (Augmented Reality) technology to help with diagnostics, troubleshooting, and repairs. This ensures you receive prompt and effective support whenever needed.

Q: How compatible are the batteries with different inverters?
A: Our batteries work with most popular inverters through CAN or Modbus communication. If your inverter brand isn't listed, provide us with its communication protocol, and we can upgrade our system. You can select the protocol on the LCD screen, ensuring seamless integration with your existing setup.

Q: Are LeFu ESS lithium batteries safe?
A: LeFu ESS uses LiFePO4 battery cells, which are safer and more thermally stable than other lithium types. These batteries do not catch fire or explode in overcharge or short-circuit situations. With a cycle life exceeding 6,000 cycles at 25°C and a 0.5C charge rate, they also have low self-discharge and stable output, guaranteeing safety and efficiency throughout their lifecycle.

Q: Are there any special requirements for installation and maintenance?
A: LeFu ESS's LiFePO4 batteries are designed for easy installation. With years of experience in off-grid inverter setup, we've made the process user-friendly and require no special tools. This streamlines implementation and ensures a smooth start to your energy journey.

Q: Do you offer OEM and ODM customization services?
A: Yes, we have a skilled technical team for custom product design, including hardware, software, and structural engineers. Final testing is done by our team. Generally, customization requires a minimum order of 300 units, with mold, certification, and other related costs covered by the customer. This service enables bespoke solutions tailored to your specific market needs.
