The KOSTAL 3×3×3 principle
Maximum flexibility. Minimal complexity.
The photovoltaic market is dynamic: storage systems are being retrofitted, e-mobility is gaining in importance and the legal framework is constantly changing. For retailers and tradespeople, this means that systems are becoming ever more sophisticated, the number of variants is increasing - and with it the planning effort.
With the KOSTAL 3×3×3 principle, the PLENTICORE inverter now provides a remedy to the increasing complexity. Instead of a multitude of different devices, KOSTAL has opted for scalable platform logic. The result is a system that adapts.
One inverter, many possible applications
At its core is a simple principle:
- 3 basic devices (S / M / L)
- 3 power levels
- 3 operating modes (solar / hybrid / battery)
This combination enables a total of 27 different application configurations - based on a reduced hardware platform.
For retailers and tradespeople, this means fewer variants, less complexity - and at the same time a wide range of possible applications.
"Less is more!"
The KOSTAL 3×3×3 principle makes it simple: SIMPLE!
The hardware remains the same and additional functions are simply activated as required. This turns a simple product into a dynamic system.
The KOSTAL PLENTICORE inverter makes it possible:
- One platform, covering many possible applications
- Standardised installation and commissioning processes
- Future-proof for trade, craftsmen and operators
- Can be retrofitted without hardware replacement
The 3×3×3 principle reduces complexity without limiting performance - and turns an inverter into a future-proof platform.
The PLENTICOIN - the fast track to your goal
A central component of the 3×3×3 principle is the PLENTICOIN. The PLENTCOIN is the single-purpose voucher for product extensions at KOSTAL: regardless of whether it is a wallbox or an inverter. Regardless of whether it is a power extension, battery activation or convenience function.
Activation can be
- immediately upon installation
- or at a later point in time
- on the construction site or in the office
without having to replace the device.
This reduces the investment hurdles for end customers and creates economic opportunities for installers and retailers. The extension is plannable, comprehensible and technically cleanly integrated.
Advantages for installers
The 3×3×3 principle supports the installer on several levels
- Operational simplification: Standardised device architecture means identical assembly sequences, familiar interfaces and consistent commissioning processes. This reduces sources of error and training costs
- Planning security despite open customer decisions: Many end customers make decisions at different times: Storage today or later? Plan a power reserve? Keep hybrid capability open? With the PLENTICORE, this decision remains flexible - without having to install a new device
- Subsequent sales potential: functions can be activated later. This creates recurring customer contacts and additional revenue opportunities - without the need for new hardware
- Reduced stock commitment in operation: fewer variants mean lower order risk and better costing reliability
Advantages for wholesalers
The 3×3×3 principle also unfolds its economic strength in retail
- SKU reduction: Instead of providing numerous specific hybrid or battery variants, the range is concentrated on a few basic devices plus expansion options
- Optimised capital commitment: Less item diversity means lower stock levels, higher turnover rates and better planning capability
- Planning with reduced forecasting risk: The uncertainty of which variant will sell more is largely eliminated. The platform covers different requirements
- Software-based extensions: PLENTICOINs cause no logistics costs, no transport damage and no storage space requirements. This makes the model economically attractive
- Market dynamics as a driver: subsidy programmes, grid requirements, storage quotas, dynamic tariffs and electromobility are constantly changing the market environment. Rigid portfolios quickly reach their limits here
Whether retail or trade: a platform approach such as the KOSTAL 3×3×3 principle makes it possible to respond to new market requirements without jeopardising existing installations. This increases investment security - for operators and specialist companies alike. With the KOSTAL 3×3×3 principle, installers and wholesalers are opting for a platform strategy instead of a wide range of variants.
