Power failure exposes weaknesses: solar systems cannot help!

Biberach, Deutschland - In June, a power failure in the Laupheim, Schemmerhofen and Schwendi regions caused some excitement. The residents found that modern photovoltaic systems (PV systems) could not provide any energy in the event of a network-side failure. Michael Maucher, graduate engineer and specialist for building technology at the energy agency in Upper Swabia, explains that the inverter, which converts the generated solar power into usable alternating current, automatically switches off in the event of a power failure. This happens because the supply network, which acts as a clock, no longer works and the balance between production and consumption cannot be maintained. Thus, sockets remained silent, cooling and freezing cabinets had to get along without electricity for some time and the sudden darkness was an unwelcome surprise for many households.

The question arises: How can PV system owners protect themselves from such breakdowns? Battery stores offer a possible solution that can release electricity via sockets. These memory can ensure that critical devices such as cell phones or refrigerators receive electricity for a few days in an emergency. Hybrid systems that both generate and store solar power can also make sense. However, the more cost -intensive network -compatible systems that represent an island solution are often unable to supply all devices with electricity at the same time, since the requested performance quickly becomes too high. Many homeowners remember to retrofit such systems in order to be self-sufficient even in the event of network failures. reports .

technical backgrounds and solutions

How does an emergency power supply actually work? According to the information from Solar experts, PV systems can be retrofitted by special emergency power sockets or inverter that enable consumers' operation during a power failure. A well -planned replacement current system supplies relevant devices in a household and improves independence in self -sufficient situations. The installation of such systems should be carried out by experts to ensure efficiency and security. One point that should not be neglected is the exact recording of the electricity requirements and the compatibility of the battery storage with the existing PV system.
solar experts emphasizes that the selection of the right system significantly depends on the individual energy needs.

A essential question for many plant owners is also the economy of these additional equipment. Just because there is a battery memory does not mean that it always offers the desired independence. Regular maintenance and monitoring are also important to ensure that the system works under all conditions. The reality shows that the actual possibilities of emergency power systems are often less than initially assumed. In the case of longer power failures, even a larger battery memory could not deliver enough energy to supply the entire household.
SMP Solar indicates the meaning in such cases.

conclusion: The consideration of how you can behave in the event of a power failure is more relevant than ever. While Germany has one of the most reliable power grids in the world and power failures are usually quickly fixed, one should not forget that good preparation can make up the difference. If you want to keep your heating, cooling or lighting systems going, you should deal with alternatives that go beyond a simple PV system at an early stage.
