Product Advantages

Modular 16kWh Stack Design

Modular 16kWh Stack Design

The system capacity is assembled from field-replaceable 16 kWh battery modules, with flexible stacking options ranging from 4 to 15 modules. It delivers precise capacity configuration and convenient on-site maintenance. For reference: a single 241.05 kWh energy storage cabinet is assembled with fifteen 16 kWh modules.
High-voltage architecture design reduces line power loss

High-voltage architecture design reduces line power loss

High-voltage topology cuts down loop current and copper loss (I²R loss). It allows the use of smaller-gauge cables, improves the system’s charge-discharge cycle efficiency, and enables miniaturization and integration of power conversion circuits.
Available matching hybrid inverter power ratings: 30/40/50 kW

Available matching hybrid inverter power ratings: 30/40/50 kW

Custom three-phase hybrid inverters enable seamless grid-tied operation and backup off-grid power supply, support rapid charge-discharge switching, and allow parallel connection of multiple units for capacity expansion.
Pre-wired & stackable cabinets for rapid on-site deployment

Pre-wired & stackable cabinets for rapid on-site deployment

The fully pre-integrated unit features stackable racks and factory pre-wired cables, drastically cutting on-site installation and commissioning time and reducing labor and space costs for commercial & industrial (C&I) projects.
Intelligent BMS for Overall Coordinated Control

Intelligent BMS for Overall Coordinated Control

The integrated Battery Management System (BMS) realizes peak shaving and valley filling as well as refined capacity control. It dynamically coordinates and schedules stacked units to boost self-consumption rate and cut electricity bills.
