A targeted attack on the critical infrastructure in south-west Berlin over the past few days has painfully demonstrated just how vulnerable our modern electricity supply is. Around 45,000 households and thousands of businesses were left without power, in some cases for days, after a central cable bridge was sabotaged. While the repair teams worked under high pressure, heating systems remained cold, servers dark and production lines stopped.
Such events are no longer a theoretical horror scenario, but a reality. For homeowners and operators of industrial properties, the question is therefore more urgent than ever: How can I protect my building from the consequences of such external influences? The answer lies in the intelligent combination of photovoltaics and certified backup systems from enwitec.
The “central network” weak point
Central power grids are efficient, but their architecture makes them susceptible to targeted disruptions. A single fire attack on a cable shaft or a bridge can paralyze entire city districts. Relying solely on the public grid here means relinquishing control over your own energy supply.
Maximum security with enwitec PowerBackup
A standard PV system switches off immediately in the event of a power failure for safety reasons. In order to continue to supply the building with its own solar power, a physical disconnection from the grid is required. This is where the PowerBackup solutions from enwitec electronic GmbH.
These systems go beyond a simple emergency power function:
- Fully automatic switchover: In the event of a blackout, the PowerBackup-Box safely disconnects the household grid from the public grid within fractions of a second.
- Real replacement current: While simple systems only supply a single socket, enwitec technology enables three-phase backup power operation. This means that the entire building – including heating pumps and lighting – continues to be supplied with power.
Intelligence meets reliability: the “PowerBackupBrain” system
The hardware solutions are complemented by intelligent energy management systems such as the “enwitec Brain”. In crisis situations such as the current sabotage in Berlin, information is the key to self-sufficiency:
- Adaptive emergency power reserve: The system uses weather forecasts and storm warnings to raise the storage level in good time before a potential grid failure occurs.
- Sector coupling: Even in the event of a grid failure, the intelligence optimally controls the energy flows to heat pumps or charging stations in order to use the available energy from the PV system and storage system for as long as possible.
Security for trade and industry
Power outages can threaten the existence of industrial companies in particular. With specialized grid and system protection solutions, enwitec also offers systems for systems up to the megawatt range. These ensure that large systems react safely to unstable grid conditions and switch back on automatically and in accordance with standards after the fault.
Conclusion: being prepared is not scaremongering, but precaution
The events in Berlin show: The security of the power supply can no longer be taken for granted. Anyone investing in a PV system today should plan backup power with enwitec’s PowerBackup solutions right from the start. This turns a simple solar system into a genuine private power plant – “Made in Germany” and ready for emergencies.
