Power storage systems and charging stations
Power storage systems for photovoltaic systems
Your photovoltaic system generates solar power right where it is needed: in your own home. As a homeowner, it is beneficial to use as much of the self-generated electricity as possible directly. But a particularly large amount of energy is often consumed at times, such as in the evening, when the sun is no longer shining — for example to cook, do laundry or to charge an electric car. This is where the use of an energy storage device is a good idea.
Power storage systems
When choosing a power storage device, there are two types: AC and DC storage. It is not always easy to decide which type is best suited for which requirements. Here is a simple overview.

DC storage vs. AC storage
DC Storage
If you are installing a new solar system, a DC storage system is often the better choice. A DC-coupled electricity storage system is connected directly to the solar cells before the electricity goes into the inverter. It is a compact unit that contains everything you need: an inverter, a charge controller, an energy management system and a battery. This complete solution is very efficient and economical as it enables a high degree of independence from external power sources.
AC-Coupled systems
AC-coupled systems, on the other hand, are installed downstream of the solar system's inverter. The electricity storage system works independently of the solar cells. With this system, however, there are energy losses because the electricity is converted twice - from alternating current to direct current and vice versa. AC systems are particularly suitable if you already have a solar system and would like to add a storage unit at a later date, as the inverter is already in place.
Hybrid power storage
There are also hybrid electricity storage systems that combine the advantages of both systems. They do not require an additional inverter and can be used with both new and existing solar systems. This makes them a flexible solution, as they can be used as a source of alternating current and direct current.
What kind of charging infrastructure do I need?
Smart Station
Eine "smarte" Ladestation ist für effizientes Laden und zukünftige Entwicklungen sehr wichtig. Eine solche Station kann nicht nur an Ihre Photovoltaikanlage angeschlossen werden, sondern ermöglicht auch das kontrollierte Aufladen und die Abrechnung des Stromverbrauchs mit anderen, die Ihre Ladestation benutzen.
Intelligente Steuersystem
Das intelligente Steuersystem stellt sicher, dass der von Ihrer Photovoltaikanlage erzeugte Solarstrom optimal zum Laden Ihres Elektroautos genutzt wird. Es verhindert auch, dass der Strom zu niedrigen Preisen ins Netz eingespeist wird.
Richtige Steckertypen
Die Auswahl der richtigen Ladestation hängt jedoch vom benötigten Steckertyp ab. In der Schweiz gibt es je nach Automarke unterschiedliche Steckertypen. Asiatische Elektrofahrzeuge verwenden meist den Steckertyp 1, während europäische Modelle oft den Steckertyp 2 nutzen. Im Zweifel fragen sie uns an, wir helfen ihnen gerne weiter.

Benefits of electric charging stations at home
Electric charging stations in private households are special facilities that make it possible to charge electric vehicles at home. They are a practical alternative to public charging stations and offer a number of benefits.
How it works
Inspection by a qualified electrician
The installation process usually starts with a qualified electrician checking your home electrical installation to make sure it can support a charging station.
Connection to the house's electrical network
As soon as the electrician confirms compatibility, the charging station is connected to your home's power grid. This includes safely integrating the station into your home electrical system.
Installing the charging station
The charging station is securely installed in a suitable location, usually near your parking space for the electric vehicle. This ensures easy access to the store.
Connect the electric vehicle:
With the charging station properly installed and connected, you can now connect your electric vehicle to the station using a specialized charging cable. This cable is designed to safely and efficiently deliver energy to your vehicle's battery.
Use of intelligent features:
Many modern charging stations have intelligent features, such as programmable charging times or remote monitoring via a dedicated app, which allow you to optimize charging times, monitor energy consumption, and control charging remotely to provide additional convenience and efficiency.
