‘Happy Birthday, PLENTICOIN’: 1 year of innovation and flexibility

A system that brings trade and craftsmanship together

In line with its motto ‘By professionals for professionals’, KOSTAL ensures that the expertise of installers is the focus of attention. This is because PLENTICOINs can only be redeemed by authorised specialist tradesmen. This model ensures that installation and commissioning are carried out by professionals, which guarantees both the quality and reliability of the products. PLENTICOINs can be purchased from qualified KOSTAL specialist wholesalers.

At the same time, PLENTICOIN offers end customers the opportunity to expand their systems individually and in a future-proof manner. By enabling product extensions to be used in a targeted manner, KOSTAL has created a sustainable, flexible and, above all, economical model for the installation and commissioning of solar systems.

After one year of PLENTICOIN, KOSTAL is reporting positive results. ‘The system has established itself as an important component in our portfolio and underlines KOSTAL's innovative strength, which inspires both customers and specialist tradespeople alike,’ says Frank Henn, Managing Director of KOSTAL Solar Electric. ‘The combination of flexibility, efficiency and quality makes PLENTICOIN a key tool for retailers, tradespeople and customers.’

Greater flexibility and transparency

PLENTICOIN allows customers to activate only the functions they need – exactly when they need them. This model ensures a fair and transparent price-performance ratio. In addition, the basic devices, such as inverters and wall boxes, can be offered at an attractive price. KOSTAL customers only pay for additional services such as the battery function or a performance upgrade when they need them. This flexibility enables the needs-based and sustainable use of all KOSTAL products.

Advantages for specialist tradesmen

The PLENTICOIN offers numerous advantages for installers:

• Quick access to product enhancements: Installers can purchase PLENTICOINs in stores and quickly and easily exchange them for the necessary activation codes in the KOSTAL Solar Webshop.
• Efficient process: The use of PLENTICOINs speeds up and simplifies the processing of product enhancements – especially with the KOSTAL Solar App in PRO mode – specifically for installers.
• Versatility: With just a few basic devices from KOSTAL inverters and wallboxes, PLENTICOINs can be used to create numerous PV systems. The small number of devices minimises storage, reduces transport distances and lowers initial investment costs
• Less training required: By reducing the number of basic devices and models, installers can increase productivity and implement various system configurations with just a few training sessions
• Support and strengthening of specialist trades: PLENTICOINs can only be redeemed by authorised specialist tradesmen. This model ensures that installation and commissioning are carried out by qualified professionals, thus guaranteeing the highest quality and reliability of the products.
