24-60kW 48-120kWh Modular Battery Storage System
Stack BESS 24-60kW 48-120kWh Modular Battery Storage System
The AceOn Stack 24-60kW 48-120kWh modular battery storage system is fully integrated with a 3 phase inverter that can operate on or off grid, up to 10 battery storage modules and an energy management system. The product is suitable for outdoor installation with an IP55 system level rating and a IP65 battery pack rating. The battery storage system is ideal for small scale commercial and industrial (C&I) applications. The battery technology used is an LFP 0.5C rated.
Scalable Energy Storage
The modular design allows a choice of battery storage size with each energy block containing 12kWh of battery storage capacity. A minimum of 4 battery modules are required providing 48kWh. Up to an additional 6 battery modules can be added providing a total of 120kWh maximum. The 3 phase inverter and energy management control is located in the top module and can be adjusted to provide power output between 24-60kW AC.

Multi-Layer Protection
PACK-level protection + millisecond rapid fusing, constructing the Great Wall of energy security.
Six-layer Battery Protection
Active Fault Isolation for Battery Packs
Equipped with an integrated BMS that continuously monitors the battery status in real time. When an individual battery module experiences an anomaly, the system can accurately identify the specific module and automatically isolate the fault module.
Millisecond-Level Seamless Switching
The system controller has a built in STS switch and an off grid switching time of <20ms, guaranteeing continuous power supply for critical equipment (e.g. medical and production facilities)
Intelligent Temperature Control
Intelligent Temperature Control
The thermal management system can be selected according to the operation scenario, including three cooling methods: natural air cooling , forced air cooling and air conditioning cooling
Fresh Air Intake+Cold Air Circulation
Cold air is circulated from the bottom of the battery pack to effectively dissipate heat, control equipment temperature, extend service life, and reduce the failure rate caused by high temperatures
Freedom to Expand Capacity as Needed
Modular design allows for easy assembly (30 minutes) and flexible expansion. Versatile solution for C&I energy needs
Lightweight Modular Unit
Single 12kWh Module <90kg
Modular design and assembly, the maximum weight of a single battery pack 90kg ,no professional mechanical equipment needed for handling. Installation is not site specific, efficient use of space, and allows easy transportation and installation indoors, outdoors, in basements, on rooftops, and more.
