Solar-Log is a manufacturer-independent monitoring system for photovoltaic installations. It is commonly used in residential, commercial and larger PV projects to visualize energy flows and centrally manage systems. This article provides an overview of features, login, data and typical use cases of Solar-Log.
What is Solar-Log Monitoring?
Solar-Log is a system for collecting and visualizing energy data from photovoltaic systems. Unlike many manufacturer-specific solutions, Solar-Log can integrate inverters and components from different manufacturers.
Its purpose is the centralized display of:
- PV yield
- electricity consumption
- self-consumption
- grid import and feed-in
- system status
Solar-Log is used by system owners, installers and energy managers.
Technical Structure & System Principle
The monitoring system is based on a local data logger connected to the PV system.
System principle:
- Solar-Log data logger on-site
- connection to inverters and optional meters
- internet connection for remote access
- data transmission to Solar-Log portal
- access via web portal or app
The data is collected, processed and then visualized.

What data does Solar-Log display?
Depending on the system and installed hardware, the following data may be available:
- PV yield
- real-time power
- electricity consumption
- self-consumption rate
- grid import
- feed-in
- system status
Note: Data availability depends on configuration and may be displayed with a delay.
A detailed explanation can be found in Solar-Log Data Explained: Yield, Consumption & Storage.
Common issues in Solar-Log monitoring
During operation, the following issues may occur:
- missing or delayed data
- communication problems with inverters
- differences between views
- login issues
These are usually caused by network configuration or system integration.
A structured overview is provided in Solar-Log Problems: Offline, No Data & Delays Explained.
When is Solar-Log sufficient and when not?
Sufficient for:
- multi-vendor systems
- commercial applications
- multiple inverters
- detailed analysis
Limited for:
- very simple systems without measurement hardware
- plug-and-play requirements
- real-time requirements at second-level accuracy
Solar-Log compared
| Criteria | Solar-Log | Manufacturer-specific monitoring |
|---|---|---|
| Manufacturer dependency | No | Yes |
| Flexibility | High | Low to medium |
| Integration | Very high | Limited |

Using data in external systems
Solar-Log provides interfaces and export options for integrating data into external systems. This makes it suitable for advanced analytics, energy management and reporting.
Frequently asked questions about Solar-Log (FAQ)
Is Solar-Log manufacturer-independent?
Yes, Solar-Log supports a wide range of inverters and systems.
Is there an app?
Depending on the setup, mobile access is available via apps or web interface.
How up-to-date is the data?
Data is updated regularly but not necessarily in real time.
Who is Solar-Log suitable for?
For residential, commercial and larger systems, especially when combining different manufacturers.
Why are Solar-Log daily values sometimes incomplete during the day?
Solar-Log daily values can be incomplete during the day because production, consumption, feed-in and storage values are still changing. A daily yield value, for example, continues to increase as long as the PV system produces electricity. Battery charging, self-consumption and grid import can also change throughout the day. For reliable analysis, completed time periods should be used.
