8kWh All-in-One LiFePO4 Solar Energy Storage System
The TezePower 8kWh All-in-One LiFePO4 ESS combines a 25.6V 314Ah LiFePO4 battery with a built-in 4.5kW hybrid off-grid inverter in one integrated energy storage system. It is designed for home solar energy storage, backup power and off-grid applications, providing a compact and convenient solution for storing and using renewable energy.
25.6V 314Ah LiFePO4 Battery — 8kWh Energy Storage
With a 25.6V 314Ah LiFePO4 battery, the system provides approximately 8kWh of energy storage capacity. LiFePO4 chemistry offers excellent safety, long service life and stable performance, making it well suited for residential energy storage and daily solar energy use.
Store excess solar energy during the day and use the stored energy when solar production is lower or additional power is needed.
Built-in 4.5kW Hybrid Off-Grid Inverter
The integrated 4.5kW hybrid off-grid inverter combines battery storage and power conversion in a single system, reducing installation complexity and saving space.
The inverter can work with solar PV and mains power according to the system configuration, allowing flexible energy management for different home energy needs.
The system is designed for off-grid operation and does not feed electricity back into the public grid.
Flexible Solar & Mains Charging
The system supports flexible charging options according to the inverter configuration, including:
-
Solar PV charging
-
Mains power charging
-
Solar PV and mains power charging simultaneously
This allows available solar energy to be used efficiently while mains power can provide additional charging when required.
Active Balancing for Better Battery Performance
The built-in BMS features active cell balancing, helping maintain better voltage consistency between cells and supporting stable battery performance.
The BMS also provides essential battery protection and monitors key operating conditions to help keep the battery working safely and reliably.
Expandable Capacity — Up to 15 Units in Parallel
The 8kWh All-in-One LiFePO4 ESS supports up to 15 identical units connected in parallel, allowing you to expand total energy storage capacity as your power needs grow. This makes the system suitable for larger home energy storage, solar power and backup power applications while maintaining a flexible and scalable setup.
Bluetooth & BMS App — Monitor Battery Data
The battery can be monitored through the BMS Bluetooth connection and BMS app.
The BMS app is used specifically to monitor battery data, allowing users to check important battery operating information such as:
-
Battery voltage / Current / State of charge (SOC) / Battery temperature / Cell information / Other battery operating parameters
This makes it easier to understand battery status and monitor daily operation.
Optional Inverter WiFi Module & App — Monitor Inverter Data
The inverter can be equipped with an optional WiFi module for remote monitoring.
The inverter WiFi module and its app are used specifically to monitor inverter data, allowing users to check inverter operating information such as PV input, AC input/output, power and operating status, depending on the inverter configuration.
This means the battery and inverter can be monitored separately through their respective systems.
All-in-One Plug & Play Energy Storage
By integrating the LiFePO4 battery and hybrid inverter into one unit, this All-in-One ESS simplifies system installation and reduces the need for separate battery and inverter equipment.
The compact integrated design makes it suitable for residential energy storage where space, installation convenience and simple system management are important.
Ideal for Home Solar & Backup Power
The 8kWh All-in-One LiFePO4 ESS is suitable for a range of applications, including:
-
Home solar energy storage
-
Residential battery storage
-
Solar self-consumption
-
Backup power
-
Off-grid energy systems
-
Daily energy storage
It provides a practical way to store solar energy and use it when needed, helping households make better use of available renewable energy.
