LVMD switching systems
What are NSHV switching systems and what are their possible applications?
LV switchgear systems, or low-voltage main distribution boards, are centralised switchgear systems used in electrical power distribution networks. They are used to safely and efficiently distribute the electrical energy that has been converted by a transformer at low-voltage level (usually 400 V).
Main functions of NSHV switching systems:
Energy distribution:
LVB switching systems distribute the electrical energy from a central point to various loads or sub-distribution boards within a building, an industrial plant or a power supply network.Protection:
They offer protective mechanisms such as circuit breakers and fuses that switch off the affected circuits in the event of overloads or short circuits in order to prevent damage to the systems and ensure safety.Measurement and monitoring:
NSHV switching systems can be equipped with measuring and monitoring devices that make it possible to monitor energy consumption and other electrical parameters in order to optimise efficiency and control operation.Switching and control functions:

NE Protection
What is NA protection and how is it used?
A NA protection, also known as grid and system protection, is a safety-related device used in electrical energy generation systems such as photovoltaic systems or combined heat and power plants. It is used to disconnect the system from the public grid when certain critical conditions occur in order to protect both the grid and the system itself.
Which standards does the NA protection from Faber E-Tec GmbH fulfil?
The NA protection from Faber E-Tec GmbH fulfils the requirements of the VDE-AR-N 4105:2018-11 standard, which is mandatory in Germany for grid and system protection for power generation systems such as photovoltaic systems. This standard specifies the minimum technical requirements for the connection and operation of energy generation systems on the low-voltage grid and ensures that the NA protection works reliably to protect both the public grid and the connected systems.
What types of systems can be equipped with NA protection?
The NE Protection is suitable for a wide range of energy generation systems, especially those that are operated on the public grid. These include
Photovoltaic systems: NA protection is essential for the safe connection of solar systems to the grid in order to prevent overloads and grid faults.
Combined heat and power plants (CHP): In these systems, the NA protection ensures safe disconnection from the grid in the event of faults in order to guarantee stable operation.
Wind turbines: NA protection is also used in wind turbines to prevent stand-alone operation and protect the system in the event of grid faults or impermissible grid parameters.
Biogas plants: In biogas plants, NA protection prevents the plant from being damaged or grid stability being impaired in the event of a grid fault by monitoring the grid parameters.
Mixed systems: Systems that combine several energy sources benefit from NA protection by ensuring that the connection is reliably disconnected in the event of grid problems.
NA protection is therefore an indispensable element for the safety and stability of power generation systems that are connected to the public grid.
What are the advantages of using NA protection?
NA protection offers decisive advantages for the safe operation of power generation systems. It continuously monitors the grid parameters and automatically disconnects the system from the grid in the event of critical deviations, protecting both the system and the power grid from damage. It also prevents unwanted stand-alone operation in the event of grid failures and fulfils the requirements of the VDE-AR-N 4105:2018-11 standard. This reliability and simple integration make the NA protection a cost-effective solution that ensures the long-term stability and security of the energy supply.

Include your specific requirements and system details so that we can provide you with a customised quote. Our team will also be happy to provide you with personalised advice to ensure that NA protection is optimally tailored to your needs.
AC-Combiner
What does the term AC mean in relation to photovoltaics?
AC in photovoltaics stands for "alternating current". In photovoltaic systems, the direct current (DC) generated by the solar modules is converted by an inverter into alternating current, which is then used in households, businesses or fed into the public grid. Alternating current is the form of electricity used in most electrical grids and appliances, as it can be transported efficiently over long distances and is required by most electrical devices.
Can a photovoltaic system that is AC-coupled also support a battery storage system?
It is possible to combine an AC-coupled photovoltaic system with a battery storage system. In such a system, the solar power generated is first converted into alternating current and fed into either the domestic grid or the public grid. The battery storage system is also charged via the AC grid by feeding surplus electricity that is not consumed directly into the battery. This concept enables flexible integration of battery storage systems, even in existing photovoltaic systems, and ensures efficient storage of solar energy and its utilisation when required, even when the sun is not shining.
What is AC coupling?
AC-coupled means that a battery storage system is integrated into an existing alternating current (AC) grid that is already fed by a photovoltaic system or another energy source. In this system, the direct current (DC) generated by the solar system is first converted into alternating current before it is fed into the grid or into the battery storage system. The battery storage system therefore works on the alternating current side of the system, which enables flexible retrofitting and increases compatibility with existing systems.
How does the inverter work within a photovoltaic system?
The inverter is the central element of a photovoltaic system, which converts the direct current (DC) generated by the solar modules into alternating current (AC). The latter is required for the operation of household appliances or for feeding into the public power grid. Once the solar energy has been converted into electrical energy by the solar modules, the direct current generated is passed on to the inverter. Here, the direct current is converted into a sinusoidal alternating current whose frequency and voltage correspond to the values of the public grid. The inverter also monitors the output of the photovoltaic system and ensures optimum energy yield.
