Product Advantages

One 261kWh Platform.
Four System Architectures.

The ZQ-FC-Z1 series uses the same 261kWh battery platform while allowing the project configuration to evolve from basic BESS to photovoltaic and solar-diesel hybrid systems.
01

261kWh LiFePO4 Platform

All four configurations use the same 261kWh battery-energy platform for consistent system capacity.

02

Four Configurations

Choose pure BESS, Solar BESS, 125kW Solar-Diesel BESS or 250kW Solar-Diesel BESS.

03

Liquid Cooling

Liquid-cooled thermal management is used across all four configurations.

04

Solar-Ready Options

Solar configurations support MPPT input from 250~850 Vdc with 120kW or 240kW power.

05

Generator Integration

Generator Port is available on both Solar-Diesel BESS configurations.

06

Parallel Expansion

125kW configurations support up to 12 units, while the 250kW model supports up to 6 units.

Available Models

Four 261kWh Configurations.

Select the system according to whether the project requires battery storage only, solar input or solar-diesel hybrid operation.
