KOSTAL - Highest quality, expandability and reliability "Made in Germany"

Anyone interested in photovoltaics, e-mobility and modern energy solutions rightly places high demands on quality, expandability and reliability.

Expandability at KOSTAL: products that grow with your requirements

Because expandability is important to me!

An expandable PV system is very important to me if my need for clean energy increases in the future. This could be the case, for example, if I need more energy for another electric vehicle. An inverter with high expandability makes it possible to easily expand the PV system later and thus produce more solar power.

A flexible system is also equipped for future changes in energy requirements and can be adapted quickly. It is therefore important to consider the expandability of the inverter when selecting it in order to save costs and effort in the long term and ensure a sustainable power supply. That's why KOSTAL.

Why is expandability so important?

Expandability is important for an inverter for several reasons. Firstly, it enables flexible adaptation to future needs. If the energy demand increases or additional solar modules are to be installed, an expandable inverter can easily integrate these changes without the need for a complete system replacement.

Secondly, expandability facilitates the implementation of new technologies, as the inverter is designed to remain compatible with future developments and components. Thirdly, it provides long-term cost efficiency, as the ability to customise and expand protects investments and reduces the need for new investments. Finally, expandability supports sustainable practices by extending the life of the existing system and reducing resource consumption for new equipment. Overall, expandability promotes the flexibility, sustainability and cost-effectiveness of solar systems.

Why is an inverter essential for operating a photovoltaic system?

An inverter is essential for the operation of a photovoltaic system, as it converts the direct current generated into the required alternating current that can be fed into the electricity grid. Without an inverter, it would not be possible to utilise the electricity produced by the photovoltaic system.

An inverter has a major influence on the performance and reliability of the photovoltaic system. A good inverter should have high efficiency, reliability and a long service life to ensure optimum performance of the photovoltaic system.

The inverter is also important for controlling and monitoring the photovoltaic system. Some inverters have intelligent controls that ensure that the inverter always operates at optimum performance. The PLENTICORE fulfils all these criteria.

Why is expandability a key decision criterion when purchasing an inverter?

The expandability of an inverter plays a decisive role in the future-proofing and flexibility of a photovoltaic system. A system that can be adapted to growing requirements offers clear added value for customers, increases the yield, supports amortisation and contributes to environmental protection.

Added value for customers through flexibility

An expandable inverter enables users to adapt their solar system to changing requirements at a later date. Be it through additional solar modules, storage solutions or new loads - a scalable solution ensures that investments can be used sensibly in the long term without the need for a completely new purchase.

Higher yields and faster amortisation

An inverter that can adapt and grow helps to maximise the yield of the system. If new PV modules or storage systems can be added later, the economic efficiency is maintained and the investment pays for itself over a longer period of time. This shortens the amortisation period and makes the system even more profitable.

CO₂ reduction and environmental protection

An expandable inverter avoids unnecessary new purchases and reduces electronic waste. Instead of having to buy a completely new system and dispose of old components, existing systems can continue to be used. This reduces material consumption and contributes to CO₂ reduction.

Future-proofing through new technologies

Technological developments in the field of renewable energies are progressing rapidly. A modular, expandable inverter makes it possible to integrate future innovations - such as smart energy management systems or optimised storage technologies - without having to replace the entire system.

An expandable inverter offers long-term benefits for the customer, increases yields, accelerates amortisation and actively contributes to environmental protection. The ability to flexibly adapt the system to new requirements makes it future-proof and economically attractive.

Why is KOSTAL a recommended supplier of inverters and wallboxes?

For over 100 years, the family-owned company KOSTAL has been synonymous with quality. With the PLENTICORE inverter and the ENECTOR wallbox, KOSTAL offers perfectly harmonised solutions for a sustainable and efficient energy supply. These products are manufactured in Germany.

The PLENTICORE inverter is a true all-rounder. It enables flexible expansion through battery storage and thus significantly increases the self-consumption rate of photovoltaic systems. Thanks to its intuitive operation and robust design, the inverter offers a durable and efficient solution that has been specially developed to meet the requirements of modern energy systems.

The ENECTOR wallbox is the perfect complement to the PLENTICORE. It enables fast and efficient charging of electric vehicles and can be intelligently integrated into the KOSTAL energy management system. This means that surplus solar power can be used directly for charging. Together, PLENTICORE and ENECTOR form a harmonious system that fulfils the requirements of a sustainable energy future.
