Knyee ES-LV-5 5.12kWh Lithium Battery
The Knyee ES-LV-5 5.12kWh Lithium Battery is a compact wall-mounted LiFePO4 battery designed for compatible solar backup power and energy storage systems. With a 51.2V nominal voltage, 100Ah rated capacity and 5.12kWh storage capacity, this battery is suitable for residential solar systems, small backup power installations and selected light commercial applications where the inverter and battery design are correctly matched.
The ES-LV-5 is designed with built-in BMS protection, CAN / RS485 / RS232 communication, Bluetooth and WiFi support, touch screen control and support for parallel expansion where the inverter and system design allow. It is a practical battery option for customers who need a clean wall-mounted lithium battery for backup power and solar self-consumption.
5.12kWh Battery Storage for Solar Backup
The Knyee ES-LV-5 provides 5.12kWh of nominal battery storage capacity, making it suitable for essential load backup and smaller solar battery systems. It can help store solar energy during the day and provide battery power during outages, depending on the inverter, connected loads, battery settings and installation design.
For many homes and small business systems, a 5.12kWh battery is a practical starting point for backup power. Runtime will depend on what loads are connected. Lights, WiFi, computers, security systems and selected plug circuits normally use far less power than geysers, ovens, stoves, kettles, pumps and air conditioners.
Wall-Mounted LiFePO4 Battery Design
The ES-LV-5 uses LiFePO4 lithium battery technology in a wall-mounted cabinet, helping create a neat and space-saving battery installation. Wall-mounted batteries are popular for garages, utility rooms, solar rooms and backup power installations where floor space is limited.
The battery has a sheet metal enclosure, compact dimensions and an IP20 protection rating, making it best suited for suitable indoor or protected installation areas. The final mounting position must be confirmed by the installer according to wall strength, ventilation, cable routing, battery access and safety requirements.
Built-In BMS Protection
The Knyee ES-LV-5 includes a battery management system designed to support safer battery operation. Protection features include temperature protection, over-current protection, short-circuit protection, over-charge protection, over-discharge protection and low-voltage protection.
Correct inverter communication and commissioning settings remain essential. The installer must confirm the correct charge voltage, discharge cut-off voltage, current limits, cable sizing and protection devices before the battery is placed into operation.
Communication and Monitoring Features
The ES-LV-5 supports CAN, RS485 and RS232 communication protocols, allowing integration with compatible inverter systems where the correct communication protocol and inverter settings are available. The battery also supports Bluetooth and WiFi functionality for monitoring and configuration where correctly set up.
Battery communication is important for lithium systems because it allows the inverter and battery BMS to manage charging, discharging and protection behaviour more effectively. Final communication compatibility must be confirmed before purchase.

Important Compatibility Notice
Before purchasing the Knyee ES-LV-5 battery, compatibility must be confirmed with the intended inverter brand and model. The inverter must support the required battery voltage range, BMS communication protocol, firmware version, charge settings, discharge settings, and battery configuration.
Incorrect battery matching can lead to communication errors, charging faults, reduced performance or unsafe operation. The battery must not be selected only by capacity. The full solar and backup system design must be checked before installation.
