1. In principle, all Solar-Log™ models (Solar-Log Base 15, 100 and 2000) are capable of reliably monitoring a PV plant. The models differ primarily in how large the plant is. The Solar-Log Base 15 can be connected up to a plant size of 15 kWp, the Solar-Log Base 100 up to 100 kWp and the Solar-Log Base 2000 is designed for a maximum of 2000 kWp Extension licences are available for certain models.

2. The following details are important to have when selecting the best data logger for your needs: plant size, the availability of Internet, inverter type and series.The selection of accessories also helps when deciding on the Solar-Log™ models..

3. Here is an overview of all Supported Components by Solar-Log™ devices: Supported components

If you have a request for PV system design, please contact us and give us so many details as possible, as they will help us to offer you a professional and optimal solution.

The Solar-Log is supplied with power via a 24 V power supply unit (if required via a 12 V power supply unit).

The Solar-Log has a battery-buffered Real Time Clock, or RTC for short. An internal circuit ensures that the battery supplies the RTC and that it only discharges when there is no external power supply for the Solar-Log.

The RTC and therefore the respective time will continue to run in the absence of an external power supply. This is important for recording the data with the correct time stamp after the power supply has been interrupted, as it may take some time to synchronise the system time on the Internet.

The battery has been sized so that the Solar-Log Base continues to record the system time for at least 3 years from production without an external power supply.

Log in with the account symbol (top right) to create a new plant under your account. Switch to "My Plants" and click on the plus symbol. Then a window appears to enter the "Plant Name" and "Serial Number." Enter the "Easy Code" if the Solar-Log™ should register automatically to the portal. Remove the top gray cover on the device to find the serial number and Easy Code. Then click on "Save." The plant is then automatically created. All the necessary information that needs to be entered in the Solar-Log™ to transfer data is located in the plant's "Access Data" section on the portal.

If it is necessary to replace a Solar-Log™ device at your plant, you do not need to register the new device. The device replacement can be performed with you existing account.

The following steps are necessary to replace a device in the Solar-Log WEB-Enerest™ portal. Log in with the account symbol. Switch to "My Plants." Go to the plant where the device needs to be replaced and click on the tab "Solar-Log™ Replacement." Enter the serial number from the new Solar-Log™ in the serial number box (remove the top gray cover on the device to find the serial number) and then click on the "Replace" button. This completes the device replacement process and the Solar-Log™ now transfers its recorded data to the WEB portal.

To create a new password in Solar-Log WEB-Enerest™, log in with the account symbol, go to "Personal information" and click on the "Password" tab. You can generate a new password in the "password" box. After clicking on "Change Password" to save the password, the password will be activated and sent via e-mail to the registered e-mail address.
