# Energy Data

### Real-time Power Overview

The home page shows your home's current energy status. In the home energy flow diagram, you can see:

* **PV power (kW):**Current solar generation status
* **Battery status:**Shows the battery charge/discharge power (kW), current state of charge (SoC, %) and operating status (Charge, discharge, or standby)
* **Home load power (kW):**Electricity being consumed by the home
* **Grid power (kW):**Shows whether power is being drawn from the grid or fed into the grid
* **Charging pile power (kW):**Displayed only when a charging pile is connected to the system

The direction of energy flow shows where energy goes between devices, helping you quickly understand the current energy usage pattern.

### Historical Energy Data

On the **Energy** page, you can review your home's generation and energy usage over different time scales. You can view:

* PV Generation
* Battery Charge/Discharge Amounts
* Home electricity consumption
* Grid import and export amounts

These data help you understand your home's energy usage habits and the system's performance at different times.

### How to Read Energy Charts

Energy charts show trends in energy changes, rather than instantaneous values.

* During the day, solar power is usually the main source of supply
* At night, the system relies more on the battery or the grid

Click the **stacked display** button at the bottom of the chart, and the energy chart will use different colors to distinguish the sources and destinations of energy, helping you intuitively understand the energy mix of the home in each time period. For example, on rainy days, more home electricity comes from the battery or the grid; on sunny days, it is usually mainly from solar power.

### Renewable Energy Achievements

**Renewable Energy Achievements** Shows how much of your home's energy use truly comes from solar and the battery. Based on the home's total electricity consumption within the selected time range, the system calculates and visually presents the proportion supplied by renewable energy. As this proportion continues to increase, your home will:

* Reduce reliance on the grid
* Lower electricity costs
* Get closer to a sustainable lifestyle

{% hint style="info" %}
Renewable energy achievements are affected by seasons and weather. In winter, when there is less sunshine, the values are usually lower than in summer. If this value remains low for a long time, it usually means solar supply is insufficient, and you may consider increasing the PV installed capacity or optimizing the system configuration.
