The provided document is a User Manual for the SUNGROW EMS300CP Energy Management Controller. This device is a web-based local monitoring system designed to optimize energy storage control and distributed power output, coordinating the commissioning and ceasing of loads. It addresses issues such as unused surplus wind and PV power, unstable loads, and varying electricity prices between peak and off-peak hours, aiming to balance power supplies and demands economically and efficiently across different application scenarios and operation modes.

Function Description:

The EMS300CP serves as a central control and monitoring unit for energy plants, primarily focusing on energy storage and PV storage scenarios. It allows users to:

Monitor System Status: View real-time running information of the plant, including energy storage data (daily charge/discharge, cumulative charge/discharge, operation status over seven days, SOC), PV information (daily yield, total yield, power factor, installed capacity, operation status over seven days), load active power, and grid active power.
Manage Alarms and Faults: Display current system faults and alarms, categorized by level and quantity. Users can click on fault IDs to view corresponding solutions.
Device Monitoring and Maintenance: Access detailed working conditions of PV, energy storage, and other connected devices. This includes real-time information for energy storage units (work mode, system chargeable/dischargeable energy, available charging/discharging power, total charge/discharge, daily charge/discharge, cell voltage/temperature, online SOC, etc.), PV units (total active/reactive power, total yield, daily yield, number of on/off-grid devices), and other devices like meters (voltage, current, total active/reactive power).
Device Management: Create and manage unit lists (Energy Storage Unit, PV Unit, Meter Unit, Other Unit), add various devices such as SUNGROW Loggers, Meters, String Inverters, and Communication Devices, and edit or delete existing devices.
Device Start/Stop: Initiate or cease operation of devices in the plant with a single touch. It supports both manual and auto startup modes for grid-connected and off-grid scenarios.
Control Methods: Implement various control strategies for the energy plant:
- Operating Parameters: Configure general operating parameters, including Local/Remote control for AGC/AVC scheduling, Dispatch Interruption Control Mode (Keep current value or Zero Power Output), and Debug Mode Switch. It also allows setting the rated capacity of energy storage and photovoltaic nominal power.
- Required Quantity Control: Limit the maximum allowable required quantity to prevent real-time power of the grid-connected point from exceeding a preset value.
- Reverse Power Relay: Prevent the PV and storage system from feeding power to the grid by automatically reducing PV power generation, discharge power, or charging batteries if discharge power exceeds load power.
- Time-of-Use Power: Operate the system automatically according to specified power levels during defined time periods, allowing for charging and discharging schedules.
- Tariff Setting: Configure different tariffs for various time periods, including maximum required quantity, price for electricity within the required quantity, and price for electricity above the required quantity.
- Force Regulation Control: Adjust the power factor to reduce power factor clauses, primarily controlling reactive power.
- Active Power Control: Control the plant to output active power based on a remote protocol or a fixed target value set on the local Web. It includes Local/Remote settings and a Control Dead Zone.
- Reactive Control: Control the plant to output reactive power based on a remote protocol or a fixed target value set on the local Web, also including Local/Remote settings and a Control Dead Zone.
- Standby Power Function: Set primary and secondary protection for the SOC of the energy storage system to ensure operation within a defined SOC range when grid-connected and reserve electricity for loads when off-grid.
- SOC Balancing: Optimize the operation of PCS units and balance the SOC of batteries across the plant to prevent damage from excessive charge/discharge and extend battery life. This function has grid-connected and off-grid scenarios with configurable SOC upper/lower limits, charge/discharge step factors, and an adjustment period.
- PID Controls: Configure PID parameters for Energy Storage Active Power, PV Active Power, Energy Storage Reactive Power, and PV Reactive Power, with preset options (quick, slow) and custom settings for scale factor, integral coefficient, and differential coefficient.
History Data: Access operation logs, history curves of device parameters, fault records, and dispatch records.
System Management: View run information (General, I/O, Forwarding), perform system maintenance (upgrade, log export, rebooting, strategy import, one-click migration, reset all settings), configure remote maintenance, and export messages.
System Time: Check and calibrate the system time, with options to synchronize with PC time or iSolarCloud, or manually set date and time.
Transfer Configuration: Configure IEC104 and MODBUS forwarding services, including point table generation/export, white list settings, and advanced settings.
Port Parameter Configuration: Set parameters for RS485 ports (COM1-COM7), Ethernet ports (ETH1, ETH2, ETH5), and WLAN (SSID, security).
License Management: View license information and import license files.
