Industrial / Commercial ESS

Battery Cluster Controller

One cluster, one management, no bias current, full discharge; charge and discharge capacity increased by approximately 7%.
Battery cell-level monitoring allows for remote fault location.
Intelligent internal short circuit warning reduces fire risk by more than 90%.
String architecture design, along with optimizer and cluster controller, enables individual replacement of battery packs.
AI intelligent arc protection automatically cuts off within 0.5 seconds.
Integrated solar energy storage solution with intelligent dispatching supports multi-mode superposition and better coordination.

Intelligent internal short circuit warning reduces fire risk by more than 90%.
Active fire extinguishing device for rapid fire suppression.
Integrated solar energy storage solution with intelligent dispatching supports multi-mode superposition and better coordination.
Battery cell-level monitoring allows for remote fault location.
Four levels of active shutdown: cell level, battery pack level, battery cluster level, and system level.
One package, one optimization; charge and discharge capacity increased by approximately 6%. ‧ Distributed cooling architecture ensures high availability for 15 years.
