Hexon Launches New 261kWh Liquid-Cooled Hybrid DC Cabinet for C&I Energy Storage and Microgrids.
In emerging energy-use scenarios such as commercial and industrial (C&I) energy storage, microgrids, energy storage systems are evolving from standalone “energy storage devices” into integrated platforms for multi-energy coordination and comprehensive power supply.
How can solar power be efficiently utilized? How can the system switch rapidly when the grid becomes unstable? How can diesel generators work together with battery storage? How can higher energy capacity be deployed when installation space is limited?
At the same time, as safety and operation & maintenance requirements continue to increase, energy storage systems must balance flexibility, reliability, safety, and lifecycle cost.
To address these requirements, Hexon Energy has launched its new 261kWh Liquid-Cooled Hybrid DC Cabinet, deeply compatible with Tier 1 75–125kW hybrid inverters.
The system integrates PV, battery storage, grid power, and diesel generation into a coordinated energy architecture, while supporting rapid on-grid/off-grid switching, m
ulti-channel MPPT, flexible energy storage duration, and layered fire safety protection.
By integrating multiple energy sources into a single cabinet, the 261kWh system takes energy storage beyond a standalone battery and toward multi-energy coordinated power supply.

01. PV + Battery + Grid + Diesel: Multi-Energy Integration for Coordinated Power Supply
Traditional energy projects often require multiple standalone devices to be connected together, resulting in a more complicated system architecture, longer installation time, and greater commissioning workload.
Hexon’s 261kWh Liquid-Cooled Hybrid DC Cabinet integrates PV, battery storage, grid power, and diesel generation into a coordinated energy system and is compatible with Tier 1 75–125kW hybrid inverters.
This enables multiple energy sources to work together according to different operating conditions and load requirements.
Key Benefits
Compatible with grid-connected, off-grid, microgrid, and diesel backup operating modes
Supports PV priority, battery energy management, and multi-energy coordinated power supply
Suitable for commercial and industrial facilities, AIDC/data centers, and remote-area microgrids
Simplifies system architecture and reduces the number of field-installed devices
Helps reduce installation, commissioning, and integration workload
One energy storage system, multiple energy sources, coordinated energy management.
02. <10ms On-Grid/Off-Grid Switching for Reliable Power Supply
For production lines, data centers, even a short-duration power interruption can result in equipment shutdowns, data risks, and significant business losses.
The Hexon 261kWh Liquid-Cooled Hybrid DC Cabinet supports <10ms on-grid/off-grid switching, enabling rapid transition to off-grid operation when grid abnormalities occur.
This provides a faster response to grid disturbances and helps maintain a more reliable power supply for critical loads.
Key Benefits
Rapid transition to off-grid operation when grid abnormalities are detected
Reduces the impact of grid fluctuations and outages on critical loads
Suitable for data centers, AIDC facilities, and critical industrial equipment
Supports complex power environments, including weak grids and islanded microgrids
Faster switching. More stable power. Greater protection for critical loads.
03. 10 Independent MPPT Channels with Up to 250kW PV Input
Distributed PV installations often involve complex rooftops, different module orientations, and varying solar conditions. Without flexible PV input management, differences between PV strings can lead to reduced energy harvesting.
The Hexon 261kWh Liquid-Cooled Hybrid DC Cabinet features 10 independent MPPT channels and supports up to 250kW of PV input, providing greater flexibility for complex distributed solar installations.
Key Benefits
10 independent MPPT channels for enhanced control of different PV strings
Supports distributed PV systems with multiple orientations and complex rooftop layouts
Supports a higher PV-to-storage configuration ratio to improve solar energy utilization
Simplifies system architecture and increases overall system integration
Coordinate PV, battery storage, and loads to unlock greater value from solar-plus-storage systems.
04. Flexible 2–8 Hour Energy Storage Configuration with 15% Less Footprint
For industrial facilities, commercial buildings, and AIDC data centers, energy storage capacity is only part of the equation.
Available installation space is equally important.
The Hexon 261kWh Liquid-Cooled Hybrid DC Cabinet supports flexible 2–8 hour energy storage configurations and uses a highly integrated cabinet design to achieve a 15% reduction in footprint, helping projects make better use of limited site space.

06. 10-Layer Hierarchical Fire Safety Protection for Multi-Level System Security
Safety is fundamental to the design of any battery energy storage system.
The Hexon 261kWh Liquid-Cooled Hybrid DC Cabinet incorporates a 10-layer hierarchical fire safety protection architecture covering both the battery Pack and cabinet levels.
The system combines detection, suppression, isolation, and directed pressure relief to establish multiple layers of protection from individual battery cells and Packs to the complete cabinet.
Pack-Level Safety Protection
Protection starts at the battery Pack level to strengthen thermal runaway risk management:
Thermal insulation and flame-retardant isolation between cells
Pressure relief valves
Feedback-controlled aerosol fire suppression
Flame-retardant metal top cover
Through thermal insulation, flame retardancy, detection, and fire suppression measures, the system helps reduce the risk of thermal runaway propagation within the battery Pack.
Cabinet-Level Safety Protection
Additional protection is implemented at the cabinet level:
Cabinet-level fire detection
Explosion-proof fans
Rear-directed exhaust
Aerosol fire suppression
Water-based fire suppression
Optional explosion vent panel
By combining multi-level detection, multiple suppression measures, and directed pressure relief, the system establishes a comprehensive safety architecture from battery Pack to cabinet.
From individual battery cells to the complete energy storage cabinet, multiple layers of protection work together to enhance system safety and operational reliabilit
