Energy Data

The AlphaESS App helps you clearly understand your home's energy usage, from real-time status to long-term trends. With this data, you can see where energy comes from, where it goes, and gradually understand the value that renewable energy brings to your life.

Real-time Power Overview

The homepage displays your home's current energy status. In the household energy flow diagram, you can see:

• PV Generation Power (kW):Current solar power generation

• Battery Status:Includes charge or discharge power (kW), current state of charge (SoC, %) and operating status (charging, discharging, or standby)

• Household Load Power (kW):Power currently being consumed by the household

• Grid Power (kW):Shows whether power is being drawn from or fed into the grid

• EV Charger Power (kW):Displayed only when the system includes an EV charger

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

Historical Energy Data

On the Energy page, you can review energy usage over different time scales. Supported views:

• Day / Month / Year data

• PV generation

• Battery charge/discharge

• Household electricity consumption

• Grid import and export

These data help you understand household energy habits and system performance during different periods.

How to Read the Energy Charts

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

• Daytime is usually dominated by solar power

• Nighttime relies more on batteries or the grid

Click the Stacked display button (when the time view is Month/Year/Total) to see different colors in the energy chart representing different energy sources or destinations. This helps you better understand household energy behavior during different periods. For example, on cloudy or rainy days, household power comes more from batteries or the grid; on sunny days, solar power typically accounts for a larger share.

Renewable Energy Achievement

The Renewable Energy Achievement shows how much of your household's energy actually comes from solar and batteries. The system calculates the proportion supplied by renewables based on the household's total consumption for the selected time range and presents it intuitively. As this proportion increases, your household will:

• Reduce reliance on the grid

• Lower electricity costs

• Move closer to a sustainable lifestyle

Renewable Energy Achievement is affected by seasons and weather. With less sunlight in winter, the value is usually lower than in summer. If this value remains low for a long time, it typically indicates insufficient solar supply, and you may need to increase PV capacity or optimize the system configuration.
