Has your solar power system been working faithfully for many years? Then now is the ideal time to think about repowering - the targeted replacement of your old inverter with modern technology from KOSTAL. In addition to more power, efficiency and future-proofing, you will also benefit from an often underestimated advantage: new warranty and service convenience.

Because what many people don't realise: Repowering not only brings your system up to the latest technical standard, but also offers you new security in operation. And that in several ways.

Many photovoltaic systems installed in Germany today are not covered by the original manufacturer's warranty. This means that if a defect occurs in the inverter, the operator must bear the full cost of repair or replacement. In addition, technical support is often limited for many older devices. In addition, many of these old devices are not compatible with modern storage systems or smart home solutions. As a result, those who continue to operate their outdated technology are no longer technically up-to-date.

By replacing your inverter with a current KOSTAL model such as the PLENTICORE or the single-phase PLENTICORE MP, you automatically secure a new factory warranty. And by registering in the KOSTAL Solar Portal, you benefit from up to ten years' warranty - protecting you from unexpected repair costs for the next decade. This warranty covers all relevant components in the inverter and offers you the security of knowing that everything will be taken care of reliably if necessary: from quick replacement or professional repair by KOSTAL Service to guaranteed availability of spare parts and documented commissioning as proof for insurance companies.

With the KOSTAL Solar Portal and the free KOSTAL Solar App, you as the operator have a complete overview of your system at all times. You can see how much electricity is being produced and consumed, visualise the storage status, the use of your wallbox or grid consumption and get a clear overview of CO₂ savings and efficiency. This turns your modernised system into a digitally controllable energy system.

Anyone who decides in favour of repowering today is investing in modern technology and also in safety, convenience and long-term reliability. With KOSTAL, you benefit from a new factory warranty on your inverter, a manufacturer with many years of experience and an established service culture, as well as a device that is already technically prepared for storage, wallbox and other components. At the same time, you get a system that is digitally controllable and comprehensively serviced - and that will give you real pleasure not only today, but also for the next ten years.

Switching to modern KOSTAL technology is more than just a replacement - it's an upgrade for your entire system. And with a new warranty, smart technology and excellent service, you can look to the future with confidence. Check repowering potential now and protect your PV system - with KOSTAL.
