KOSTAL - Highest quality, full equipment and reliability "Made in Germany"

Anyone interested in photovoltaics, e-mobility and modern energy solutions rightly demands high standards of quality, full equipment and reliability.

KOSTAL inverters enable the full functionality of a PV system

Because full equipment is important to us!

As an environmentally conscious family, we attach great importance to a fully equipped PV system in order to maximise the sustainability and efficiency of our everyday life. A complete solution consisting of an inverter, battery storage system and wallbox enables us to make optimum use of the solar power generated - whether for the household, storage or charging our electric car. With the PLENTICORE G3, KOSTAL is the first manufacturer in the world to even offer the option of power expansion. This means that if the PV system is to be expanded at a later date, the output of the inverter can simply be increased without having to purchase new hardware.

KOSTAL impresses us with the seamless integration of all components, ease of use and maximum efficiency. The smart control system, which ensures that surplus electricity is utilised in the best possible way, is particularly important to us. Thanks to the reliable "Made in Germany" quality and the flexibility to expand the system as required, KOSTAL is the ideal choice for us to live sustainably, independently and future-proof. That's why KOSTAL.

Why is full equipment so important?

Full equipment in an inverter is crucial as it significantly improves the overall functionality and efficiency of the photovoltaic system. Firstly, full equipment enables the integration of advanced features such as real-time monitoring and intelligent control, which ensure the optimum performance and efficiency of the system. Secondly, it often includes extensive protection mechanisms against electrical faults, which increase the longevity and reliability of the system.

Thirdly, a fully equipped solution ensures that the inverter is compatible with different system configurations and that future expansions or technology advances can be easily integrated. Finally, a full feature set can increase user-friendliness by enabling easier operation and maintenance. In summary, being fully equipped provides peace of mind that all necessary functions and safety precautions are optimally covered, maximising the overall performance and lifespan of the solar installation.

Why is an inverter so important in combination with a photovoltaic system?

The importance of an inverter in conjunction with a photovoltaic system lies in the fact that it converts the direct current generated by the system into usable alternating current. This means that the electricity can be fed into the grid and is suitable for consumption. An inverter also monitors and controls the photovoltaic system to ensure reliable and efficient operation. For safe utilisation, an inverter should offer high efficiency, a long service life and comprehensive protection. Overall, the inverter is an indispensable component of a photovoltaic system that ensures its performance and reliability.

Why is it worth opting for full equipment when purchasing a PV system?

The decision to opt for a fully equipped inverter is advantageous for users of photovoltaic systems in several respects. An inverter is the centrepiece of every PV system, as it converts the direct current (DC) generated into usable alternating current (AC). However, its comprehensive features make it a multifunctional device that optimises power generation as well as the efficient use and storage of the electricity generated. The following features and requirements are all met by the KOSTAL PLENTICORE.

Automatic updates (AutoUpdate)

An inverter with automatic software updates ensures that the system is always up to date. Regular updates not only improve performance, but also safety. At the same time, functions are expanded so that the system can easily fulfil future requirements without the need for expensive retrofits. This is guaranteed with the PLENTICORE thanks to the AutoUpdate function.

SG Ready: Networking with heat pumps and energy management

SG Ready (Smart Grid Ready) is a key feature that enables the inverter to be connected to heat pumps. This means that surplus solar yields can be utilised efficiently, for example to heat water or support the heating system. This reduces dependence on fossil fuels and lowers energy costs. The intelligent control system enables optimum distribution of energy in real time.

Compatibility with battery storage

A fully equipped inverter is compatible with various battery storage systems. This means that surplus solar power can be stored and used when needed, for example at night or in bad weather. The option of connecting a battery maximises self-consumption and makes the PV system less dependent on the power grid. This is a clear advantage, especially with rising electricity prices.

Expansion of functionality and power

A high-quality inverter offers the option of integrating additional functions and power expansions. For example, it can be supplemented with additional modules or storage solutions. This is particularly important for users who want to gradually expand their PV system in order to be prepared for increasing energy requirements in the long term.

WLAN connectivity

An integrated WLAN function makes monitoring the PV system particularly convenient. Users can view the operation, output and self-consumption of their system in real time via apps or web portals. This not only promotes transparency, but also enables early fault detection and maintenance.

KOSTAL BackUp Switch: Security of supply in the event of a power failure

The KOSTAL Backup Switch enables the operation of household appliances in the event of a power failure by allowing stored solar power to continue to be used. For households that rely on a constant power supply, this is a crucial feature to ensure convenience and security. This is optionally available for the PLENTICORE G3.

DC overvoltage protection

Integrated DC overvoltage protection protects the system from damage caused by lightning strikes or overvoltages. This not only reduces the risk of expensive repairs, but also increases the service life of the entire system. As PV systems are often operated for decades, this protection is an important part of a long-term investment. This is available as an option for the PLENTICORE G3.

Future-proofing and investment protection

The combination of all these functions means that a fully equipped inverter such as the PLENTICORE offers a high degree of future-proofing. Whether it is the integration of new technologies such as smart home systems, compatibility with additional energy storage systems or adaptation to future requirements of the electricity market - a fully equipped system ensures that the PV system remains flexible and efficient in the long term.

That's why KOSTAL.

KOSTAL has been developing innovative technologies for more than 100 years and stands for quality. With the PLENTICORE inverter and the ENECTOR wallbox, the German family-owned company KOSTAL offers sophisticated solutions for the use of renewable energy.

The PLENTICORE inverter enables easy integration of energy storage systems and significantly increases self-consumption of solar energy. Its high efficiency and user-friendliness make it the ideal choice for households and businesses that prioritise sustainability.

The ENECTOR wallbox complements this solution with intelligent charging of electric vehicles, which can be perfectly combined with photovoltaic systems. With these products, KOSTAL is supporting the energy transition and offering future-proof technologies. Incidentally, both products are "made in Germany".
