Higher Performance and Greater Yields

A new KOSTAL inverter offers significantly better performance compared to older models. Equipped with cutting-edge technology, it converts solar power more efficiently and ensures optimal energy yield.

Even with weak sunlight or partial shading, you can achieve maximum results. More performance means more solar energy for self-consumption and grid feed-in – a clear advantage for system owners.

Greater Efficiency with Reduced Losses

Modern KOSTAL inverters set new standards in efficiency. Innovative technologies minimise energy losses when converting DC into AC. This results in higher yields and improved economic viability. Operators benefit from an optimised ratio between input and usable energy – with minimal conversion losses.

More Flexibility Thanks to Storage Integration

New KOSTAL inverters allow easy integration of battery storage. This increases self-consumption and reduces dependency on rising energy prices. Excess energy can be stored and used when needed – for maximum flexibility and independence for both residential and commercial systems.

Ideal for E-Mobility

KOSTAL inverters can be linked with KOSTAL wallboxes, allowing electric vehicles to be charged with solar power from your own roof. This increases energy independence and reduces ongoing costs.

A smart solution for environmentally friendly mobility – seamlessly integrated and ready for everyday use.

Smart Sector Coupling

KOSTAL enables intelligent sector coupling by linking power generation, storage and usage – including heat pumps, wallboxes or immersion heaters. These systems work together seamlessly.

This makes solar energy usage smarter and more efficient – both sustainable and cost-effective.

Full Warranty for Peace of Mind
A new KOSTAL inverter comes with full warranty coverage, providing maximum security and protection against unexpected costs. The warranty can be extended to 10 years free of charge, ensuring long-term peace of mind and investment protection.
