Your Added Value and Benefits

Valuable Time and Cost Savings

The Solar-Log Base is small, compact and ideal for the installation on a top hat rail system in a distribution box. Thanks to the simplest handling, all of the devices can be installed quickly and easily. The connection to the individual modules is done with an integrated bus system.

With Solar-Log Base, it is possible to measure and evaluate the signal quality of the inverter communication (RS485). The horror of long cable lengths and costly oscilloscope troubleshooting become a thing of the past.

New starting in Q3: Solar-Log™ Direct Marketing
Previously, an external router was required to transmit data to the direct marketer. Staring in Q3, it is possible to make secure VPN date transfers without any additional hardware. This integration not only saves money from the hardware, but also the installation.

New: Solar-Log™ - EnBW Direct Marketing Solution
We offer the complete solution from our partner EnBW from the Solar-Log™ Website "Solutions & Service / Direct Marketing." Install Solar-Log Base and register for direct marketing within 5 minutes.

With Solar-Log Base devices, the required licenses are activated free-of-charge during the installation for 30 days. During this time, you can purchase the licenses from the License Shop and register remotely from the comforts of your office.

Tailored to Individual Plant Needs

Interface elements and various software licenses can be purchased according to the needs of the plant operator. Only the solutions that are really needed have to be purchased. It is no problem to purchase additional licenses at a later time.

The modular design of the Solar-Log Base provides total flexibility. Depending on the requirements, the functions for each PV plant can be individually selected.

The customized optimization of self-consumption is another strength of our new product generation. With the intelligent interaction with all components of your plants, you achieve higher security and greater yields.

Solar-Log™ is an effective and customizable power management system for your requirements that offers numerous functions. Both individual and legal requirements can be practically implemented.
