KEY FEATURES
Highly integrated.
Integrating Solar Inverter, Battery PCS, Battery Pack, and EMS into one powerful energy system；
Modular and stackable design,all is plug and play and cableless allows it to be truly calable on demand and flexible in configuration.
Multi Layers Safety protection
The battery has six safety protections: fire module, cell temperature monitoring, auto-heating, heat-resistant pads, and pressure relief valve.
Redundant Design
The system remains operational if one module failure, with seamless balancing between groups and compatibility for mixing old and new modules without performance limited.
Low-Temperature Operation
Bi-directional pulse heating, enabling use at -40°C. It eliminates polarization and suppresses lithium plating, enhancing efficiency while ensuring product longevity.
Smart Management
The cloud platform real-time monitors, offering comprehensive visual and digital categorization.With in-depth insights into key metrics, simplifies maintenance processes, ensures stable operation, and enables remote system upgrades.
