32kWh+12kW All-in-One Energy Storage System
The TezePower 32kWh All-in-One ESS integrates a high-capacity 51.2V 628Ah LiFePO4 battery, 12kW three-phase hybrid off-grid inverter, Smart 300A BMS, 5A active balancing system, and built-in fire extinguisher into a single cabinet. With built-in dual MPPT solar pv charging, mains grid charging, three-phase output, multiple communication interfaces, and optional WiFi monitoring, it provides a complete solution for solar energy storage, energy management, and reliable backup power. The Plug & Play design reduces external wiring and simplifies installation, while the built-in wheels make the mobile cabinet easy to position and relocate.
Designed for residential and small commercial energy storage, this all-in-one system supports solar energy storage, backup power, off-grid operation and time-of-use energy management.
Supports solar PV charging, utility grid charging, or dual-source charging simultaneously. With peak and off-peak energy management and off-grid backup capability, the system ensures reliable energy supply. It can charge the battery from the utility grid but does not support feeding electricity back to the grid.
Available in 32kWh, 30kWh and 28kWh configurations, the system provides flexible energy storage options for different power requirements.
Important:
This is an off-grid inverter. It does not support grid-tied operation or feeding electricity back to the public grid.
The system can support mains charging where applicable, but charging from the grid should not be confused with grid-tied power export.
Battery monitoring and inverter monitoring are separate functions.
BMS WiFi → monitors battery/BMS data
Optional inverter WiFi module → monitors inverter data

Built-in Fire Extinguisher Inside the Battery Enclosure
A temperature-sensitive fire extinguisher is built directly inside the battery enclosure. This integrated fire protection design provides an additional layer of protection against abnormal heat and potential thermal events.
Smart Monitoring & Communication
The system supports RS485, CAN and USB communication interfaces and can be equipped with optional WiFi for remote monitoring and system management.
Mobile Cabinet Design
The integrated cabinet features built-in wheels, making the system easier to position and move during installation while providing greater flexibility for different application environments.
Applications
Residential Solar Energy Storage
Store excess solar energy during the day and use it later to increase solar self-consumption and reduce dependence on grid electricity.
Three-Phase Home Energy Storage
The 12kW three-phase hybrid inverter makes the system suitable for larger homes, villas and properties equipped with three-phase electrical systems.
Backup Power
Provide reliable backup energy during grid interruptions and help keep essential household loads such as lighting, refrigerators, communication equipment and pumps operating.
Off-Grid Energy Storage
Suitable for remote homes, farms, cabins and other locations where reliable grid electricity is unavailable or limited.
Small Commercial Energy Storage
The high-capacity LiFePO4 battery and three-phase hybrid inverter are suitable for workshops, small businesses, agricultural facilities and other commercial applications.
Peak & Valley Energy Management
Store energy during lower-cost periods and use stored energy during higher-cost periods to improve energy cost management.
The TezePower All-in-One ESS integrates a LiFePO4 battery and three-phase hybrid inverter into one system, allowing solar energy, grid power and stored battery energy to work together.
The system is suitable for three-phase homes, villas, farms, workshops, small businesses, off-grid properties, solar energy storage and backup power applications.
