The Knox Powerwall 7.1 51.2V 100Ah IP65 Lithium Battery is a high-performance energy storage solution designed for solar power and backup systems that require outdoor installation. With a usable energy capacity of 5.12kWh, this battery is built to provide stable, long-lasting power for homes, businesses, and off-grid applications.
Built with LiFePO₄ (Lithium Iron Phosphate) chemistry, the battery ensures enhanced safety, thermal stability, and a long cycle life of 8000+ cycles at 80% Depth of Discharge (DoD). Its IP65-rated enclosure provides excellent dust and water resistance, making it suitable for outdoor wall-mounted installations in harsh environments.
The smart Battery Management System (BMS) offers complete protection from over-voltage, under-voltage, overcurrent, short circuits, and thermal issues. The Bluetooth-enabled LCD display allows for real-time diagnostics and performance tracking, while its parallel expansion support enables users to scale the system with up to 15 units for higher energy storage.
This battery is compatible with a wide range of inverters, including Voltronic, Growatt, Goodwe, Deye, Victron, and others, providing flexible integration for various solar and backup power systems.
