The Welion lithium-iron LiFePO4 Battery Energy Storage System is a highly efficient and safe solution for residential energy storage. It features lithium-iron phosphate (LiFePO4) technology, which offers several advantages over traditional lead-acid batteries, such as high energy density, long lifespan, and a wide operating temperature range. The system is designed to work with household solar or grid power, ensuring uninterrupted energy supply during outages. It integrates advanced intelligent management to monitor battery performance, protect against over-voltage, over-current, and temperature anomalies, and provide real-time status monitoring via a control panel. The system also includes remote telemetry capabilities and a built-in intelligent balance module to prolong battery life. Installation, operation, and maintenance must be handled by trained professionals, and the battery is equipped with safety features like grounding requirements and temperature control mechanisms. The system can be used in parallel configurations to increase storage capacity, making it suitable for a wide range of household energy storage needs.
