Greater Intelligence in Energy Management: KOSTAL PLENTICORE now compatible with ENEQUI

KOSTAL Solar Electric is expanding the possibilities of its proven hybrid inverters: The PLENTICORE plus and PLENTICORE G3 models are now officially compatible with the energy management system from ENEQUI. Users benefit from increased flexibility, a higher self-consumption rate, and long-term optimization of their electricity costs.

With this new compatibility, operators of KOSTAL inverters can now take advantage of QuiPower Energy Management. ENEQUI’s system analyzes household energy flows in real time and intelligently controls consumers, battery storage, and EV charging stations. This ensures that generated solar energy is utilized with maximum efficiency: Surplus power charges the battery, electric vehicles are charged at favorable times, and load peaks are strategically avoided.

 

The benefits for users: 

  • Maximized self-consumption: PLENTICORE reliably stores solar power in the connected battery. ENEQUI intelligently decides when to charge the storage or feed energy into the grid.
  • Cost efficiency: By factoring in variable electricity tariffs and consumption profiles, energy flows are managed to achieve long-term cost reductions.
  • Flexibility for e-mobility: EV charging processes can be aligned with solar yields and tariff structures – ensuring both sustainability and economic efficiency.
  • Relieving the power grid: Smart peak shaving reduces load peaks and helps stabilize the public grid.
  • Ease of use and future-proof design: Integration is based on standardized interfaces, ensuring fast commissioning and flexible expansion with additional components.
     

“With the integration of ENEQUI, we provide our customers with an additional way to intelligently manage their energy flows. Whether it’s PV generation, battery storage, or e-mobility – our PLENTICORE inverters form the foundation for a future-proof energy system,” says Andreas Schmalenberg, Product Manager at KOSTAL.

CEO of ENEQUI Michael Wenngren adds: “We are delighted to partner with KOSTAL, a leading European innovator in solar and inverter technology made in Germany. By combining our smart energy management with KOSTAL’s highly efficient PLENTICORE series, we empower homeowners and businesses to optimize their energy use, reduce costs, and actively contribute to a more sustainable energy future.”

Compatibility applies to the PLENTICORE plus G2 and PLENTICORE G3 model ranges in battery inverter mode, complementing the already wide selection of supported battery systems and smart home solutions. With three MPP trackers, optional battery inputs, and outstanding efficiency ratings, KOSTAL inverters provide the ideal platform for sustainable energy supply – now even smarter through the partnership with ENEQUI.

About KOSTAL Solar Electric:

Power electronics for PV systems: From Germany. For Europe. From KOSTAL.

KOSTAL Solar Electric was founded in 2006 as a subsidiary of KOSTAL Industrie Elektrik and is now a company within the KOSTAL Group. Specialising in photovoltaics from the outset, KOSTAL Solar Electric has established itself as one of the leading suppliers of inverters for private and commercial solar systems.

Development and production take place in Germany – synonymous with the highest quality standards, reliability and product safety. With eight additional locations in Europe, KOSTAL Solar Electric guarantees comprehensive service and support – directly on site.

 

Three-phase only

With the new PLENTICORE G3 universal inverter, retailers and tradespeople can cover 27 applications with just 3 basic devices. Since its market launch in 2024, this has significantly reduced storage, training costs, initial investment and transport costs.

 

Single-phase only

With the new PLENTICORE MP G3 universal inverter, retailers and tradespeople can cover 15 applications with just two basic devices. Since its market launch in 2024, this has significantly reduced storage, training and initial investment costs, as well as transport costs.

 

Three-phase and single-phase

With the new third-generation PLENTICORE and PLENTICORE MP universal inverters, retailers and tradespeople can cover more than 40 applications with just a few basic devices. This has significantly minimised storage, training, initial investment and transport costs since its market launch in 2024.

 

KOSTAL products provide customers with key tools for the intelligent generation, storage, control and use of solar energy. KOSTAL inverters can also be used to operate and control heat pumps, air conditioning units, charging stations and heating elements. The same applies to the use of dynamic electricity tariffs: With the ‘intelligent battery use’ function, connected storage units can be filled via the KOSTAL inverter during periods of low tariffs. The ‘time mode’ on the KOSTAL Wallbox ENECTOR also charges your own electric car when electricity prices are low.

KOSTAL also offers its own high-voltage battery, KOSTAL HELIVOR HV, which works perfectly with PLENTICORE. Cyber security is also a top priority at KOSTAL: all inverter data is stored exclusively on servers in the EU. In addition, communication with the devices is secured by personalised access control. Changes to the inverter parameters can only be made by authorised KOSTAL installers.
