# Advanced Settings

{% hint style="info" %}
**Important Notice**: If you are not clear about these settings, please consult your installer or technical support before making changes to ensure the parameter settings match your hardware connections and energy service agreement.
{% endhint %}

### Basic Settings

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

#### Differences Between Startup Modes

* **Passive Mode**: Local intelligent management, with the system centrally dispatched by the local EMS. After parameter configuration is completed, the energy storage equipment will strictly follow the preset control strategy and run automatically throughout, without the need for real-time manual intervention.
* **Third-party Dispatch Mode**: The system is connected to and accepts unified dispatch from a third-party platform. In this mode, to avoid command conflicts, the system will simplify local strategies and retain only core safety and protection parameters such as electricity tariff settings, reserved backup power, and feed-in control, ensuring efficient execution of dispatch commands.

#### Control Strategy

* **Local Mode**: Power parameters are set directly through the cloud platform or the device's local web page. This mode is designed specifically for the installation and commissioning stage, making it convenient for technicians to perform rapid configuration and function verification on site.
* **Remote Mode**: The system establishes a long-term connection through EMS's physical communication interface. In this mode, the management side can remotely issue control commands, enabling precise cross-space control and energy dispatch of devices.

### Three-phase Imbalance Regulation

This is a power balancing tool designed for complex power consumption environments. In scenarios where three-phase load distribution is uneven, three-phase imbalance control can intelligently adjust the PCS single-phase output, ensuring that the current and power at the grid connection point are always in a safe and balanced state, preventing system risks caused by single-phase overload.

#### 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 as much as possible.
* **Charge and Discharge Together**: While maintaining three-phase power balance, the system strictly follows the principle of "charge and discharge together," ensuring the consistency and reliability of energy storage system operation.
* **Intelligent Monitoring**: Real-time monitoring of each phase's load status, with all adjustment processes automatically completed by the system backend, without affecting your normal electricity use or production activities.

#### Protecting Your Power Consumption Safety

* **Eliminate Overload Risks**: Effectively reduce the risk of tripping 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 current, optimize the power consumption performance at the grid connection point and improve overall energy efficiency.
* **Fully Automatic Safety Protection**: No manual real-time monitoring of load changes is required. The system responds immediately, saving you from cumbersome on-site inspections and manual allocation.

{% hint style="info" %}
Note: After enabling this function, the system will operate according to the single-phase current or power upper limit you set. It is recommended to complete the initial limit setting under the guidance of the installer.

### Demand Control

This is an intelligent monitoring tool designed specifically to reduce electricity costs. In scenarios where billing is based on the "maximum power consumption (demand)," the demand control function acts like a 7x24h on-duty "power consumption monitor," monitoring grid connection point power in real time and strictly preventing power usage from exceeding limits.

#### How It Helps You Avoid Excess Electricity Costs

* **Real-time Monitoring**: The system monitors the total power of the household around the clock. Once it detects that power consumption is approaching the preset "maximum allowable demand," the regulation mechanism will be triggered instantly.
* **Multi-energy Complementarity**: It prioritizes energy storage battery discharge and fully utilizes PV output. By reducing power drawn from the grid and smoothing instantaneous peaks in consumption, it ensures that the power at the connection point does not exceed the limit.
* **Invisible Control**: The system automatically adjusts according to actual power demand without frequent manual intervention, achieving optimal energy efficiency without affecting normal production or daily life.

{% hint style="info" %}
Tip: To achieve the best cost-control effect, please accurately set the "maximum allowable demand" parameter according to your electricity contract.

### Anti-backflow Control

When PV generation and energy storage discharge are sufficient, the anti-backflow function ensures that excess electricity does not illegally flow back into the grid. By adjusting system output in real time, it keeps your power station operating within policy limits and effectively avoids grid-connection compliance risks.

#### Round-the-clock Avoidance of Feed-in Risks

* **Strict Feed-in Control**: The system constantly monitors the power at the grid connection point. Once it detects that the total power from PV and energy storage exceeds the site load demand, it immediately activates the protection mechanism.
* **Fast Response**: The system automatically adjusts according to real-time trends: first reducing energy storage discharge or switching to charging mode, and if necessary, precisely limiting PV output to ensure the connection point power does not exceed the limit.
* **Intelligent Valley Filling**: Supports custom maximum feed-in power. By setting a positive value, you can even achieve a "valley filling" effect, making station operation more flexible.

### Off-grid Operation

In the extreme case of losing the external grid, the energy storage system can maximize power supply duration through PV-storage-diesel generator cooperation and load classification technology, ensuring that core production and daily life are not affected.

#### PV-Storage-Diesel Generator Cooperation

The system automatically balances the operation of PV, batteries, and diesel generators, aiming for lower fuel consumption while ensuring power supply.

* **Fully Automatic Coordinated Power Supply**: The system dispatches PV and battery output in real time. The diesel generator is started automatically only when power is insufficient or specific time conditions are met, achieving seamless switching.
* **Intelligent Start/Stop**: Precisely controls the diesel generator based on battery SOC or preset time periods. This avoids long periods of inefficient generator operation and greatly reduces fuel costs and equipment wear.
* **Environmental Priority Strategy**: Make maximum use of clean PV energy, reduce dependence on fuel, and make off-grid power both economical and environmentally friendly.

#### Load Classification

When off-grid power is limited, the system will prioritize critical loads based on battery state of charge (SOC).

* **Priority Gradient Management**: When power is low, the system follows the principle of "sacrifice general loads first, then protect critical loads." When power recovers, it automatically restores power step by step in order of "core first."
* **Excellent Endurance Solution**: By orderly cutting off non-essential loads, it multiplies the runtime of critical equipment and effectively avoids losses caused by sudden power outages across the station.
* **Fully Automatic Step Control**: Built-in strict numerical logic (following: general load recovery SOC > critical load recovery SOC > critical load cut-off SOC), no manual switching on/off is required.

{% hint style="info" %}
Note: To ensure the load classification function takes effect, please be sure to contact the installer to confirm that the hardware wiring has been physically partitioned according to "critical/general" loads.
{% endhint %}

### Auxiliary Control - SOC Calibration

Accurate energy data is the foundation of intelligent energy efficiency management. SOC calibration eliminates minor deviations caused by long-term operation through a complete controlled charge. It is like a system "self-focus" process, keeping the battery's displayed state of charge consistent with the real condition.

#### Why is calibration needed?

* Restore reality: eliminate the error between displayed energy and actual energy, avoid "false power" or sudden jumps in energy, and let you grasp the most authentic power reserve.
* Strategy baseline: Whether it is reserved backup power or demand control, accurate SOC is the baseline for all intelligent strategy execution, ensuring system commands are precise to the millimeter.
* Long-term stability: Regular calibration can effectively reduce false triggering of protection mechanisms, improve the operating expectations of the energy storage system, and make management more predictable.

&#x20;When you find that the energy display remains unchanged for a long time or does not match expectations, enabling this function can quickly restore the system's sensing accuracy.
