Intelligent Multi-Source Charging
The 32kWh All-in-One ESS supports three charging modes:
Solar Charging
Charge the battery directly from solar PV energy.
Grid Charging
Charge the battery using utility grid electricity when required.
Solar + Grid Charging
Use solar and grid power simultaneously to provide greater charging flexibility.
Important: This system supports charging from the public grid but does not support exporting electricity back to the public grid.
Peak Shaving & Valley Filling
The built-in time-slot charging and discharging function allows users to schedule battery operation according to electricity tariffs.
Store energy during lower-cost periods and use stored energy during higher-cost periods to improve energy management and potentially reduce electricity costs.
Smart Battery Monitoring
The integrated Smart BMS provides battery monitoring and protection functions.
The BMS supports Bluetooth monitoring, allowing users to check battery operating data through the corresponding mobile app.
An optional WiFi module is available for inverter monitoring. The WiFi module uses its dedicated app to remotely view inverter operating data.
This means the battery BMS monitoring and inverter WiFi monitoring are two separate monitoring functions.
Built-in Active Balancing & Fire Protection
The battery includes a built-in active balancing module to help maintain voltage balance between cells.
For additional safety, the system also features a temperature-sensitive built-in fire extinguisher designed to provide automatic thermal-triggered fire protection.
12kW Three-Phase Hybrid Off-Grid Inverter
The integrated 12kW three-phase inverter provides 230/400V AC output and supports up to 24kW peak power.
With dual MPPT and up to 18kW total PV input, it is designed for larger residential solar PV systems.
The system can supply household loads from solar energy, stored battery power or the grid according to the selected operating mode.
Plug & Play All-in-One Design
The battery and inverter are integrated into one cabinet, reducing the need for separate battery and inverter installation.
The Plug & Play design simplifies system wiring and installation, while the built-in wheels make the unit easier to move into position.
Available Capacity Options
The same 12kW three-phase All-in-One system is available in:
-
28kWh – 51.2V 560Ah
-
30kWh – 51.2V 587Ah
-
32kWh – 51.2V 628Ah
The 32kWh / 628Ah version provides the highest storage capacity for larger homes and higher energy requirements.

Precautions
•No matter what the charging model is, once the temperature of the cell is above the absolute charging temperature, charging should be stopped.
• Please check the orientation of the positive and negative terminals before packaging.
•Connect the terminal or wire to the battery module, and pay attention to insulation to prevent short circuits.
• When not in use for a long time, the battery should be stored in a cool and dry place (<35°C, 30%~50% SOC, charge and discharge once every 3 months).
• Do not place the battery in direct sunlight or a heat source.
• Do not wear metal jewelry (such as rings, watches, accessories, etc.) when handling the battery unit.
