Power failure in Laupheim: Why fail photovoltaic systems!

Biberach, Deutschland - A recently accrued power failure in the Laupheim, Schemmerhofen and Schwendi area has scared the owners of photovoltaic systems (PV systems). The technical problems that occurred in mid -June led to many households without electricity. The sockets remained silent, cooling and freezing cabinets had to do without energy- an unpleasant situation that became a reality for some households. Michael Maucher, graduate engineer and specialist in building technology from the energy agency in Upper Swabia, describes the background: "The PV systems cannot deliver any electricity in the event of a power failure because the inverter turns off," he explains. Why? The supply network, which acts as a clock in electricity production, is also canceled in the event of a failure. This means that the inverter can no longer maintain the balance between electricity generation and consumption, and the system remains silent.

But what can homeowners do to be prepared for such failures? Battery stores offer a solution that have specific sockets. As a result, the stored electricity can be handed over as required, which can be helpful in an emergency. Hybrid systems are another option: they direct the PV current generated directly into the memory and use it at the same time what can increase independence from the public power grid. "However, network -compatible systems are more complex and cost -intensive," warns Maucher, adding that such island solutions cannot always operate all devices at the same time, since the required performance could be too high for some households.

emergency power and replacement current solutions

More and more consumers are interested in emergency powerful battery storage, which enable to stay on the network even during a power failure. An emergency power switch, such as Solaredge, makes it possible to manually activate the energy supply manually in the event of a power failure. The company has continuously developed its storage solution since 2018 and has launched suitable models, such as the Home Battery Niedervolt and Hochvolt, as required. These models enable an emergency power supply and can also retrofit older systems. Solaredge emphasizes that homeowners are to be supplied during a power failure and to what priority.

These backup systems also work in island operation and keep critical consumers such as refrigerators and lighting. "However, the right configuration is crucial," said the experts. Therefore, homeowners should definitely evaluate their individual energy needs and make a cost-benefit analysis. Finally, solid energy storage promotes independence from external electricity suppliers and can significantly improve the quality of life. It is also important that the installation of experts is carried out to ensure the maximum benefits of the systems.

The reality of the power supply in Germany

Although Germany has one of the most reliable power grids in the world and failures are usually quickly remedied, the concerns of many citizens are understandable. Finally, power outages can be triggered by various causes, such as natural events or technical problems. That is why more and more people are interested in increasing their independence and considering alternative solutions. A PV system with battery storage and emergency electricity function is an attractive option here to be supplied even in difficult times. In this sense, it is advisable to regularly check your own system and, if necessary, to retrofit to be equipped for the future.
