Features of 16.07-32.15kWh All-in-One Energy Storage System
Grade-A LiFePO4 Cells with Intelligent Battery Management
The battery pack uses brand-new Grade-A 314Ah LiFePO4 cells with a cycle life exceeding 6,500 cycles for long-term power stability. The built-in smart BMS monitors cell voltage, current, and temperature in real time to protect against overcharging, over-discharging, and short circuits. A front-mounted 4.3-inch touchscreen enables installers and technicians to inspect operational metrics without external diagnostic tools.

Compact Design with Flexible Installation Options
To accommodate different installation spaces, the 16.07–32.15kWh system supports both floor-stacked and wall-mounted installation. With a depth of only 260mm, it helps reduce the space required for installation. Rated IP21, it is suitable for dry, well-ventilated indoor environments.
• Single module (16.07kWh): 483 × 260 × 1070mm, approx. 136.5kg
• Dual module (32.15kWh): 483 × 260 × 1685mm, approx. 254.5kg

High-Current Output and Surge Power Support
The battery module delivers up to 200A of continuous discharge current and can provide 205A for up to 5 seconds. The recommended charge and discharge currents are 40A and 100A, respectively.
Combined with the inverter’s 10kVA surge power, the 16.07–32.15kWh system can handle everyday loads as well as appliances with higher starting currents, such as air conditioners, water pumps, and small motors.

10ms Backup Switching and Dual AC Outputs
The integrated 6.5kW inverter supports up to 6500W of PV input with an MPPT operating range of 60–450VDC and provides dual AC outputs. During a grid outage, the all in one system switches to backup power in approximately 10ms in UPS mode and delivers pure sine wave AC output. Dual AC outputs make it easier to separate critical loads from higher-power appliances and manage backup power more effectively.
Multiple Power Inputs and Remote Monitoring
Beyond solar PV, the 16.07–32.15kWh all in one system accepts utility grid or diesel generator power to handle changing supply conditions. The inverter features a 3.5-inch LCD screen alongside RS232, RS485, and CAN interfaces. With the optional Wi-Fi module, users and service teams can monitor solar generation, load usage, and battery SoC via mobile app or web browser.
