Sigenergy mySigen Data Explained: Achieving Full Visibility of Yield, Consumption & Storage
For a general overview, see Sigenergy mySigen App: Features, Login & Data Overview
What data does Sigenergy mySigen display?
Depending on system configuration and installed measurement hardware, the monitoring view provides visibility into the system, and users can track solar generation, battery status, and grid interactions in one place:
PV yield
real-time power
electricity consumption
self-consumption rate
grid import
feed-in
battery state of charge
system status
The mySigen app provides real-time energy monitoring and shows key features in kWh from different sources, but not every system automatically displays all values, and what users see can vary by system configuration or region if data availability or settings differ. Scope and accuracy depend on inverter type, meters and storage system.
Yield in mySigen
Yield describes the energy generated by the photovoltaic system. It is measured in kilowatt-hours and is typically displayed as:
daily yield
monthly yield
yearly yield
total yield
Yield only shows how much electricity was produced, not how it is used.
Power vs Yield: important difference
A common misunderstanding is confusing power with yield.
Power (kW) is the current electricity production
Yield (kWh) is the amount of energy generated over time
Fluctuating power values are normal and depend on weather, time of day and consumption.
Understanding consumption and self-consumption
Consumption describes the total electricity demand of a household or business, and monitoring it can help a home or business manage electricity use with greater efficiency to better meet demand.
Self-consumption is the share of generated solar power that is used directly or later supplied from storage. Real-time tracking helps identify abnormal energy use, while trend analysis supports forecasting and budgeting to save on energy spend.
High yield does not automatically mean high self-consumption, since part of the energy may be fed into the grid. With the mySigen app, personalized system configuration and smart load management give you more control and can shift each device toward solar energy, reducing reliance on grid electricity.
Grid import and feed-in
Grid import
Grid import is the electricity drawn from the public grid when the PV system does not produce enough energy or the battery is empty. It can rise step by step during low PV output or high-load periods, so each increase should be read in context rather than treated as a fault.
Feed-in
Feed-in is the portion of solar energy that is not used on-site and is exported to the grid.
Simplified formula:
PV yield = self-consumption + feed-in
Some monitoring interfaces use Sankey-style displays to show the way energy flows between PV, battery, home use, and the grid.
Small measurement deviations are possible.
Storage values in Sigenergy mySigen
For systems with battery storage, mySigen provides a storage view designed to show battery-related values in a clear way:
battery state of charge in percent
charging power
discharging power
Users can also monitor battery performance and charging status in the mySigen app, with real-time updates commonly shown every 10 seconds where available.
The battery increases self-consumption by storing excess solar energy.
Why do values fluctuate during the day?
Fluctuations are technically normal and caused by:
changing solar irradiation
varying electricity demand
internal energy management
charging and discharging cycles
Monitoring tools can help alert users to sudden spikes in energy consumption so corrective action can be taken.
Individual values should not be evaluated in isolation.
Autonomy and self-consumption rate
mySigen often displays metrics such as:
autonomy level
self-consumption rate
These values are useful for long-term evaluation but should not be interpreted based on a single day.
Data delay in Sigenergy mySigen
Displayed data is updated with a delay.
This means:
no guaranteed real-time data
updates typically occur every few minutes
daily values are only complete at the end of the day
For reliable analysis, completed time periods should be used.
Common misunderstandings about mySigen data
high yield does not mean high autonomy
low feed-in is not an error
differences between app and web portal are normal
short-term fluctuations are system-related
Data should always be interpreted in context, and Sigenergy monitoring uses ai as an AI-driven energy management system to support that analysis rather than replace careful judgment.
When is the data sufficient and when not?
Sufficient for:
single systems
residential standard monitoring
overview of energy flows
optimization of self-consumption
Limited for:
multiple locations
cross-manufacturer analysis
precise billing
advanced reporting requirements — monitoring reports can still support sustainability or ESG reporting as an addition, but they are not the same as precise billing data, and expectations for reporting, data handling, or compliance may differ by area.
Why do yield and consumption not match?
Yield describes generated energy, while consumption describes used electricity. Some energy is fed into the grid or stored.
Why does my electricity meter show different values?
Utility meters are authoritative. mySigen uses internal measurements that may differ.
Why can’t I see consumption data?
Without suitable measurement hardware, consumption cannot be displayed correctly.
Is the data real-time?
No. The data is updated with a delay and is intended for analysis.
