Energy Scheduling
Manual Strategy
Supports manual microgrid and off-grid switching, distributed power generation, energy storage, and adjustable equipment commands for remote control actions.
Planned Curve
Users can independently configure electricity price templates based on local time-of-use electricity rates, set charging and discharging power for energy storage during different time periods, and create peak shaving and valley filling strategy templates. The functionality to configure strategies on a daily and weekly basis is provided. Adaptable to multi-regional and multi-price electricity environments, the strategy operation mode is optimized for various scenarios.
Demand Control
By connecting the total meter to the low-voltage side of the main transformer, the system real-time collects the demand value. When the demand value reaches the set limit, it triggers demand control. The system then adjusts the energy storage by reducing charging, discharging, lowering the charging power of charging stations, or decreasing the power consumption of adjustable loads, based on the configured parameters.
Dynamic Expansion
By connecting a total meter to the low-voltage side of the main transformer to real-time collect transformer load rates, protection is triggered when the transformer load rate reaches a set limit. The system then performs actions such as reducing charging, discharging, lowering the charging power of charging stations, or decreasing the power consumption of adjustable loads, based on configured parameters.
Anti-Backflow Control
By connecting a total meter for real-time collection of reverse power data to the low-voltage side of the main transformer, the system performs actions such as placing energy storage in standby, reducing discharge, charging, or reducing PV power output when reverse power occurs and reaches a set limit. The system's anti-reverse flow strategy is implemented through software protection. To achieve faster and more reliable protection, an additional reverse power protection device is required, which will immediately trip and protect upon detecting reverse current.
Backup Power Feature
During system operation, EMS coordinates and controls the execution of SOC protection for the energy storage system, ensuring the system operates within the set SOC range. A certain electric power range is reserved for backup capacity, which can be customized. It can provide emergency power supply to the load during grid power outages.

Tailored strategies to meet customer requirements are available.
