New: Voice Service with Solar-Log™

17. May 2018

Geislingen/Binsdorf, Germany, 17 May 2018 – Now with the power of Solar-Log™, if you need information about your PV plant, just ask for it! Solar-Log WEB Enerest™ is now compatible with Amazon Alexa’s Voice Service to answer important questions about your solar PV performance. Solare Datensysteme GmbH will be presenting this new means of communication, new smart energy features, plus the new Gateway Solar-Log 50 at the Intersolar in Munich.  The Solar-Log 50 is a cost-effective plant monitoring solution for the residential market segment. New features for "smart energy" offer more specific heat pump control and more functions for monitoring battery systems and charging stations.

Ask Alexa – She now knows the current status of PV plants
Soon Solar-Log WEB Enerest™ will allow PV plant owners to use the Alexa Voice Service to make verbal inquiries about their own PV plant performance. At Intersolar 2018, Solar-Log™ Skill will be available in Amazon's Alexa Skills store. Questions like, "Alexa, how is my plant?" or "Alexa, how much money have I earned with my plant?" can be answered in either English or German. Plant owners will also be able to ask questions like, "when is the best time to vacuum?". The answer is not based on how dirty the floor is, but rather on the current amount of available PV power and the expected PV surplus over the next two days. With this new Solar-Log WEB Enerest™ function, PV energy becomes more present and PV monitoring becomes simpler and more intuitive for plant owners to use.

Skillfully monitor small plants - Gateway Solar-Log 50
In combination with the Solar-Log WEB Enerest™ online portal, the Gateway Solar-Log 50 provides reliable and cost-effective PV plant monitoring. This new solution is especially attractive for the price-sensitive market segments of residential plants (up to 15 kWp) and all existing plants. These segments require products that deliver functions tailored to the needs of the target group and are open for expansion. The Solar-Log 50 is a rail mounting model that provides all relevant information like PV yield and consumption data, for effective plant monitoring on the Solar-Log WEB Enerest™ portal.  The Solar-Log WEB Enerest™ processes the recorded data, offers numerous reports, and has analysis tools for the efficient monitoring and use of PV energy. Solar-Log 50 add-on functions can be enabled by purchasing licenses. For example, there are licenses to increase the installed plant output allowed to 30 kWp and to enable power reductions (x% reductions).

500 Gateway Solar-Log 50 Giveaways at Intersolar
Solare Datensysteme GmbH is giving away a Gateway Solar-Log 50 to each of the first 500 visitors at the trade fair booth (B2/260). Questionnaires were sent with the Solar-Log™ invitation newsletter. Those interested should fill this questionnaire out and bring it to the SDS Intersolar booth. Those who present a completed questionnaire and are among the first 500 visitors will receive two years of Solar-Log WEB Enerest™ service free of charge along with their Solar-Log 50.

Smarter Energy - Charging Stations, Heat Pumps, and Battery Systems
Developments in the area of smart energy are moving along at a quick pace. The Solar-Log™ PV monitoring system has transformed into an energy management system. The integration of charging stations for electric cars plays an important role in this transformation. For example, the Solar-Log™ system in combination with a KEBA charging station provides optimized charging for electric cars. A charge requirement setting ensures that the car always reaches its minimum charge even when PV energy is not available. When there is a PV energy surplus, the Solar-Log™ informs the KEBA charging station that there is additional power to charge the car beyond the minimum charge level. The charge data is recorded and visualized with the Solar-Log WEB Enerest™ portal.

Save energy with precise heating controls
Combining photovoltaic with heat pumps offers another potential way to optimize the consumption of self-produced power. The basic idea is to have the heat pump use the surplus PV power. Depending on how the heat pump is connected to the Solar-Log™, a release signal or a surplus is sent to the heat pump. Heat pumps from IDM CTA, Hoval and Stiebel-Eltron can even be connected to the Solar-Log™ system via their own protocol. The protocol connection to the IDM heat pumps additionally includes transferring the yield forecast data. Based on the weather forecast, the Solar-Log WEB Enerest™ calculates the specific yield forecast for the current day and the following two days. IDM heat pumps factor in this data for the next 12 hours, allowing power consumption to be scheduled to ensure efficient heat pump operation.

Effectively saving energy
Battery systems are the most effective solution for the independent use of PV electricity. A major benefit is that the electricity can be stored and then used later regardless of the time of day or amount of sun. Integrating battery storage with the Solar-Log™ system allows measured values such as the battery voltage, current charge level, and unloading capacity to be available directly in the Solar-Log™ Web interface. As a helpful analysis option, the current charge is displayed as well as the charge history for the last seven days. The Solar-Log™ provides the user with additional information from the storage medium to assist in using the battery solution more effectively. Important components here are the electricity savings from using the battery and the efficiency of the battery solution itself. The user sees energy usage from the battery and the savings of using that instead of purchasing electricity from the grid.
