Repowering for your PV system - more power, more future
Repowering brings your photovoltaic system up to date: higher efficiency, longer service life and better cost-effectiveness. As a manufacturer, we at KOSTAL rely on future-proof technologies that will make your system fit for the years to come. We will be happy to provide you with further information and recommend a KOSTAL partner in your area on request.
Repowering of a PV system
Many operators of a photovoltaic system do not realise that their inverter has been in continuous use for over ten years - and is therefore often no longer state of the art. Yet the inverter is the centrepiece of your PV system: it plays a key role in determining how much solar power you can actually feed into the household grid and consume yourself.
Older devices not only operate at a lower level of efficiency, they also often do not offer modern interfaces for battery storage, wallboxes or heat pumps. Added to this are possible failures, a lack of guarantees and limited monitoring functions. The good news is that you don't have to replace the entire system for more power and future-proofing - just the centrepiece.
A technical and economic gain
A modern KOSTAL inverter offers you several advantages:
- Efficiencies of over 98 % for more yield
- More MPP trackers for flexible configuration, even with east-west orientation
- Interfaces for storage, wallbox, heat pump and smart home systems
- Convenient app and portal connection for monitoring and control
Replacement is also economically worthwhile: just a few per cent more annual yield often amortises the investment within a few years. With a suitable battery storage system, you can increase the proportion of self-consumption and thus permanently reduce electricity costs. You also benefit from a new guarantee and a low risk of failure.
Starting point for your energy management
A new inverter is the key to a holistic energy management system. Whether battery storage, e-car charging station or heat pump - you can intelligently network, control and optimise your energy in future. This will increase your independence from the energy supplier, protect your investment and increase the value of your property in the long term.
Utilising subsidies and tax benefits
In many regions, there are attractive subsidy programmes for retrofitting and storage integration. In addition, photovoltaics and battery storage systems are generally subject to 0% VAT - an advantage that makes the purchase even easier.
Simple, fast, uncomplicated
Switching is often easier than you think: In most cases, no new cable is required, installation only takes a few hours and there is no need to re-register the PV system, as long as the output remains the same. Planning, dismantling, installation and commissioning are carried out by a certified KOSTAL installer.
More transparency with digital monitoring
While older systems hardly provide any data, the KOSTAL Solar App allows you to keep an overview at all times: Yield and consumption data in real time, push notifications in the event of faults and full control over your energy flows - simple, easy to understand and mobile.
