Kostal inverters and accessories

Kostal is a German manufacturer of solar inverters. Here installers and system operators find the PLENTICORE G3 and PIKO CI series, plus Smart Energy Meter, licence cards and the ENECTOR wallbox (EV charger), sorted by output class.

First choose by output and system size. The PLENTICORE models come in sizes S, M and L, while the PIKO CI types with 30, 50, 60 and 100 in the designation cover higher output classes. Whether and which battery can be connected is stated on the product page. The Smart Energy Meter records consumption and feed-in at the grid connection.

Our range includes PLENTICORE S, M and L G3, PIKO CI 30, 50, 60 and 100, the Smart Energy Meter G2 with activation code, PLENTICOIN cards and the ENECTOR AC 3.7/11.

The range is broad, extending from cards and accessories to inverters for commercial systems. Therefore always compare output class, number of phases and scope of accessories before you compare two products.

Grid registration and installation belong in the hands of a qualified electrician. If you have questions about components, you can reach us on +49 931 760 260 40 or by email at kontakt@energie24.shop.

Frequently asked questions

What do I need the activation code for?

According to the product designation, the activation code unlocks functions of the Smart Energy Meter. Which ones exactly is stated in the manufacturer's information. Check before buying whether your meter needs it.

What are PLENTICOIN cards?

The cards are accessories for the inverter and are available in variants for Germany and for the EU excluding Germany. What they are used for in detail can be found in the manufacturer's data sheet.

Does the ENECTOR suit my system?

The ENECTOR AC 3.7/11 is a wallbox whose designation names two output levels, 3.7 and 11 kW. Whether it can be integrated into your Kostal system, we are happy to clarify before you order.

    The KOSTAL Smart Energy Meter (KSEM) is an energy meter with a wide range of functions. Thanks to additional computing power in the device, it is technically prepared for future functions and tasks and offers the optimal solution for all KOSTAL inverters. A major advantage of the KSEM is the standard pre-configuration for the PLENTICORE plus, PIKO IQ and PIKO MP plus. This means direct installation is possible without adjusting parameters or making further settings. KOSTAL Smart Energy Meter: optimal use of energy The KOSTAL Smart Energy Meter enables optimal use of energy in the household. With the energy meter, 3-phase energy measurement takes place in real time. The measurement data is transmitted to the inverters via standard interfaces. This allows the KSEM to support the energy management of KOSTAL PLENTICORE plus, PLENTICORE BI, PIKO IQ and PIKO MP plus inverters. In combination with a PIKO 4.2 - 20 or PIKO 36 EPC, the KOSTAL Smart Energy Meter is a replacement for the PIKO BA Sensor. The inverters can be set up in the KOSTAL Smart Energy Meter with the aim of maximizing solar self-consumption and displaying own/household consumption in the solar portal. For this, the KOSTAL Smart Energy Meter must be integrated into the KOSTAL Solar Portal.
