Repowering with battery storage

More self-consumption and independence with KOSTAL

Modern battery storage - the plus for repowering

Store energy when you need it - and use it when you need it

Many photovoltaic systems have been installed without battery storage in recent years. Back then, the technology was more expensive, there were no subsidy programmes and self-consumption played a lesser role. Things are different today: With a modern battery storage system, you can make your system fit for the future - and get significantly more out of your solar energy. Retrofitting is particularly ideal for repowering, i.e. replacing older inverters.

Repowering with battery storage - a perfect match

A battery storage system is the centrepiece of an intelligent energy system. It stores the solar power produced during the day and makes it available exactly when it is needed - in the evening or at night, for example. This significantly increases self-consumption and reduces the consumption of expensive grid electricity.

If the inverter is being replaced anyway during repowering, this is the perfect time to integrate a storage system. Modern KOSTAL inverters from the PLENTICORE series offer a prepared, disconnectable battery input for this purpose. This means that you can install the storage system directly or simply add it at a later date - without additional conversions.

Advantages of modern battery storage at a glance

More independence from the power grid

With a storage system, you can use your self-generated solar power even when the sun is not shining. This makes you less dependent on fluctuations in the electricity price and reduces your energy costs in the long term.

Future-proof and flexible

Whether smart home integration, dynamic electricity tariffs or new legal requirements - a modern storage system is prepared for them. The technology can be flexibly expanded, for example if you want to integrate a wallbox or heat pump at a later date.

Maximum efficiency and a long service life

Modern storage systems work with high charging and discharging capacities, which maximises efficiency. High-quality components ensure a service life of over 10 years and more.

Backup power capability

In combination with the KOSTAL BackUp Switch, a suitable storage system can continue to supply your most important consumers in the event of a power failure - for added convenience and security. The KOSTAL PLENTICORE inverter reliably takes over the control in the optimum interaction of all components.

Sustainability that pays off

Higher self-consumption means less feed-in to the grid - and therefore a direct reduction in CO₂ emissions. If you consume your own solar power, you reduce the load on the electricity grid and actively contribute to the energy transition. At the same time, you save money because every kilowatt hour you consume yourself costs you only a fraction of the current grid electricity price.

Utilise funding opportunities

Battery storage systems are subsidised in many federal states and municipalities. This can significantly reduce the investment. Tax benefits are also possible if storage systems are installed as part of a repowering project.

Ready for repowering: KOSTAL PLENTICORE inverters

Perfect combination: KOSTAL + storage

KOSTAL inverters are compatible with numerous leading storage manufacturers - including BYD, Dyness, VARTA, ZYC, Pylontech and others. This means you will find the right solution for every need: from compact home storage systems to large systems for high energy requirements.

Thanks to "Plug & Play" installation and automatic detection, commissioning is quick and uncomplicated. In conjunction with the KOSTAL Solar app, you have full control over energy generation, energy flows and savings at all times.

The best time is now

A modern battery storage system turns your PV system into a future-proof energy system. Repowering offers the ideal opportunity to take this step - with minimum effort, maximum efficiency and high flexibility for the coming years.

With KOSTAL and a suitable storage system, you can get more out of your PV system and every kilowatt hour of sunshine.
