Many homeowners already have a functioning photovoltaic system that reliably supplies electricity. However, instead of replacing the entire system, in many cases it makes more sense to expand it in a targeted manner. Existing components such as PV modules, cabling and substructures can still be used. By using modern technology - such as a PLENTICORE inverter - the system can operate more efficiently and self-consumption can be significantly increased.

Instead of disposing of existing technology, it is upgraded through targeted retrofitting. This conserves resources, is sustainable and makes the existing PV system both economically and ecologically fit for the future.

Every household has different energy supply requirements and for many, expanding the photovoltaic system is particularly worthwhile. Owners of electric cars benefit from using their own solar power directly for charging - this reduces charging costs and increases independence from the electricity market. Households with heat pumps can control their operation using electricity in a targeted manner, thereby reducing the load on the grid and increasing efficiency.

Those who already have a battery storage system can optimise intermediate storage and increase their own consumption by expanding it. And households with high daily electricity requirements have the advantage of being able to use the electricity they generate themselves exactly when it is needed - without having to make expensive purchases from the grid.

As a system provider, KOSTAL does not stand for isolated individual products, but for a perfectly harmonised, integrated energy system. The universal PLENTICORE inverter is compatible with numerous storage systems such as BYD or Varta and can be easily connected to heat pumps, wallboxes and home energy management systems (HEMS). Thanks to the modular design, your system can grow step by step - for example by retrofitting a storage system at a later date - and thus adapt flexibly to your individual needs.

With the KOSTAL Solar app, you can keep an eye on your entire energy supply at all times - simply, clearly and without any prior technical knowledge. You can see in real time where the generated electricity is coming from and where it is going. The intuitive operation makes it easy to use for all age groups, while clear visualisations promote an understanding of your own energy flows and give you full control.

An extension makes your PV system fit for the future, increases your independence and reduces your energy costs in the long term. Tip: Take advantage of funding opportunities and special offers! Contact your certified KOSTAL installer now and get advice on your individual expansion options.
