Basic Settings

By selecting the appropriate mode and control logic, you can ensure the system receives the most stable and efficient control support across different application scenarios.

Differences Between Startup Modes

• Passive Mode: Local intelligent management; the system is centrally scheduled by the local EMS. After parameter configuration is completed, the energy storage device will strictly follow the preset control strategies, operate fully automatically, and require no real-time manual intervention.

• Third-Party Dispatch Mode: The system connects to and accepts unified dispatch from a third-party platform. In this mode, to avoid command conflicts, the system streamlines local strategies and retains only core safety and protection parameters such as tariff settings, reserved backup power, and anti-feedin, ensuring efficient execution of dispatch commands.

Control Strategy

• Local Mode: Set power parameters directly via the cloud platform or the device's local Web page. This mode is designed for installation and commissioning, allowing technicians to quickly configure and verify functions on site.

• Remote Mode: The system establishes a persistent connection through EMS's physical communication interface. In this mode, the management side can issue remote control commands to achieve precise cross-time-and-space control and energy dispatch of the device.

Three-Phase Imbalance Regulation

This is a power-balancing tool designed for complex electrical environments. In scenarios with uneven three-phase load distribution, three-phase imbalance control can intelligently adjust the PCS single-phase output to ensure the current and power at the grid connection point remain safely balanced, preventing risks from single-phase overloads.

How the System Will Operate

• Single-Phase Adjustment: The system independently and precisely adjusts the current or power of each phase according to the set limits, minimizing differences between phases.

• Charge and Discharge in Sync: While maintaining three-phase power balance, the system strictly adheres to the "charge and discharge in sync" principle to ensure consistency and reliability of the energy storage system operation.

• Intelligent Monitoring: Real-time monitoring of each phase's load status; all adjustment processes are automatically completed by the system backend without affecting your normal power usage and production activities.

Protecting Your Power Safety

• Eliminate Overload Risks: Effectively mitigate risks of trips or equipment damage caused by excessive load on a single phase, ensuring the long-term stability of the power system.

• Improve Power Quality: By automatically balancing three-phase currents, optimize the performance at the grid connection point and enhance overall energy usage efficiency.

• Fully Automatic Safety Protection: No need for real-time manual monitoring of load changes; the system responds immediately, saving you tedious on-site inspections and manual adjustments.

Demand Control

This is an intelligent monitoring tool designed to reduce electricity costs. In billing scenarios based on "maximum power demand (demand)", the demand control function acts like a 7x24h standby "power monitor", continuously monitoring gateway power to prevent overuse.

How It Helps You Avoid Excessive Electricity Bills

• Real-time Monitoring: The system monitors total household power around the clock. Once consumption approaches the preset "maximum allowable demand", it will instantly trigger regulation mechanisms.

• Multi-energy Complementarity: Prioritize dispatching energy storage battery discharge and fully utilize PV output. By reducing grid power draw and smoothing instantaneous peaks, ensure gateway power does not exceed limits.

• Seamless Control: The system automatically adjusts according to actual power demand without frequent manual intervention, achieving optimal energy efficiency without affecting normal production or life.

Anti-Feedin Control

When PV generation and energy storage discharge are abundant, the anti-feedin function ensures excess energy does not illegally flow back into the grid. It adjusts system output in real time so your plant operates within policy limits, effectively avoiding grid-connection violations.

Around-the-Clock Feed-in Risk Avoidance

• Strict Feed-in Control: The system constantly monitors gateway power. If the total power of PV and storage exceeds on-site load demand, it will immediately activate defense mechanisms.

• Agile Response: The system automatically adjusts based on real-time trends: first reduce storage discharging or switch to charging mode, and if necessary precisely limit PV output to ensure gateway power stays within limits.

• Smart Valley Filling: Supports custom maximum feed-in power. By setting a positive value, you can even achieve a "valley filling" effect, making the plant operation more flexible.

Off-grid Operation

In extreme cases of loss of the external grid, the energy storage system will use PV-storage-diesel cooperation and load grading technology to maximize extension of power supply time, ensuring critical production and life are not affected.

PV-Storage-Diesel Cooperation

The system automatically balances operation of PV, battery, and diesel generator to secure power supply while pursuing lower fuel consumption.

• Fully Automatic Cooperative Power Supply: The system schedules PV and battery output in real time. The diesel generator is automatically started only when energy is insufficient or specific time conditions are met, enabling seamless transition.

• Intelligent Start/Stop: Precisely control the diesel generator based on battery SOC or preset time periods. Avoid long periods of inefficient generator operation, significantly reducing fuel costs and equipment wear.

• Environmentally Preferential Strategy: Maximize use of clean PV energy, reduce reliance on fuel, and make off-grid power both economical and environmentally friendly.

Load Grading

When off-grid energy is limited, the system will prioritize critical loads based on battery SOC.

• Priority Gradient Management: When power is scarce, the system follows the principle of "shed general loads first, protect critical loads later." As power recovers, it will automatically restore power in order according to "core priority."

• Excellent Endurance Solution: By orderly cutting nonessential loads, multiply the runtime of critical equipment, effectively avoiding losses from sudden full-site power outages.

• Fully Automatic Step Control: Built-in strict numeric logic (follow: general load recover SOC > critical load recover SOC > critical load cut-off SOC), no manual switching required.

Auxiliary Control - SOC Calibration

Accurate energy data is the foundation of intelligent energy management. SOC calibration eliminates small deviations accumulated over long-term operation through a single controlled full charge. It's like a system "self-focus" that keeps the displayed battery energy consistent with the real state.

Why Calibration Is Needed?

• Restore Reality: Eliminate the discrepancy between displayed and actual energy to avoid "phantom" energy or sudden jumps in readings, letting you know your true power reserves.

• Strategy Baseline: Whether for reserved backup or demand control, accurate SOC is the baseline for all intelligent strategies, ensuring system commands are executed precisely.

• Long-term Stability: Regular calibration can effectively reduce false triggers of protection mechanisms, improving the operational expectancy of the energy storage system and making management more certain.

When you notice the energy display remains unchanged for a long time or does not match expectations, starting this function can quickly restore the system's sensing accuracy.
