So small and yet so many functions: The Solar-Log200 is a yield evaluation tool, an alarm system and a forecasting tool all in one device.

Saving and importing data

The Solar-Log200 possesses a 2 gigabyte micro SD memory chip. The device saves data on it in five-minute intervals - uninterrupted, for 20 years. In addition, an extra capacitor buffer memory saves the data from the last 50 days just in case. All of the data can be saved manually on the local PC or automatically on a selected homepage in the internet.

The data is stored in the globally compatible CSV format, a simple text file in which individual data is separated by semicolons. This standard allows existing stored data to be read easily, and also to be quickly imported. Even manual additions of written records are thus completed in a matter of minutes.

Graphic data preparation

With the Solar-Log200 you are able to evaluate the yield of your house installation simply, quickly and reliably from your home PC. Data can also be easily integrated into your personal homepage. The web-based software allows both tabular and clear graphic display of daily, monthly and annual yields. The possibility of having the installer establish a connection to Solar-Log™ WEB increases functionality, for example by enabling current evaluation of comparisons between plants.

Alarm function

Every 15 seconds Solar-Log™ analyzes the inverter status, the yield profile and the characteristics of supply into the power network. Four coloured status LEDs on the device itself show whether everything is functioning smoothly or if there are malfunctions or failures.

Using the web, yield and alarm messages sent via email or SMS can be configured as desired locally on your PC using the operator homepage or Solar-Log™ WEB. This is how you keep the smooth function of your photovoltaic plant reliably under control.

Your solar technician can link the Solar-Log200 with the professional monitoring function in Solar-Log™ WEB on request. He will then be automatically notified in the event of malfunction and thus ensures that your plant is always running reliably and trouble-free.

Yield forecasting and degradation calculation

With the Solar-Log200 you not only see the yield that your photovoltaic plant has already attained. The Solar-Log™ also conducts yield forecasts using the experienced data stored in the software. Deviations in the yield, for example due to blocked sunlight or damage can thus be quickly recognized and remedied.

It is not only damage which leads to a decreased output for the plant, aging modules do too. Solar-Log™ incorporates the so-called module degradation into the yield evaluation and takes into it account when analyzing errors.

Easy Installation - einfache Installation

With Solar-Log Easy installation it is now easier to install the Solar-Log. The Solar-Log is doing automatically an inverter recognition on all most common inverters and the configuration of these inverters is done automatically within the Solar-Log.

For the internet connection the Solar-Log is registering itself on the Solar-Log™ WEB registration server. The user can then pull the Solar-Log™ from there to his Solar-Log WEB™ Classic II account or Solar-Log™ WEB commercial edition account with the PC at his office.


The Solar-Log200 is optionally available with a Bluetooth module for wireless connection to the new inverter generation from the manufacturer SMA. This allows a cordless connection between the inverter and the Solar-Log™ - rapid and simple installation, with mounting as desired.

Solar-Log™ with WiFi

The Solar-Log 200/500/1000  is also available with WiFi option. This applies for the standard Solar-Log as well as for the Bluetooth version. An internet cable connection is not required. Prerequisites are only a WiFi router. WiFi Repeater might be requiriered on poor signals.
