Note: In some countries, legal restrictions apply to single-phase inverters. In Germany, for example, the upper limit is 4.6 kW feed-in power. The PLENTICORE MP is available in a country-specific version.

PLENTICORE MP – The new generation in single-phase design

With the PLENTICORE MP, KOSTAL is now launching the latest generation of its successful inverter as a single-phase version. You benefit from all the advantages of the third PLENTICORE generation – in a compact design and optimized for smaller photovoltaic systems.

Technological pioneer from German production

As the world's first single-phase inverter with modular power and function adjustment, the PLENTICORE MP sets new standards in flexibility and efficiency. It not only converts solar power extremely effectively into usable household electricity, but also excels as a hybrid or battery inverter. It can efficiently store excess energy in a connected battery storage system – and even reliably takes over during power outages thanks to its integrated backup power option.

Modular expandable – for maximum flexibility

A key feature is the scalable performance. The output power can be flexibly adjusted using so-called PLENTICOINs – without having to replace devices.
This simplifies planning, installation and subsequent retrofitting.

Whether 3.0 to 4.0 kW in the S version or 4.6 to 7.0 kW in the M version – the inverter grows with the requirements and can be expanded at any time if necessary.

Versatile – from new installation to retrofitting

The PLENTICORE MP is suitable for both new construction and the modernization of existing PV systems.
Its third DC input allows the direct connection of a high-voltage battery, which means it can also be used as a pure battery storage inverter.
Thanks to its wide memory compatibility, it offers maximum design freedom.

Backup power supply made easy

In conjunction with the KOSTAL BackUp Switch and a connected battery, the PLENTICORE MP reliably supplies energy even in the event of a power failure.
The manual switch is simply mounted on the DIN rail in the control cabinet – quickly, easily and cost-effectively.

Perfect combination: inverter & wallbox

For a particularly efficient self-consumption concept, the PLENTICORE MP can be ideally combined with the single-phase KOSTAL ENECTOR 7.4 wallbox.
In this way, the self-generated PV power is used intelligently to charge the electric car – sustainably, cost-effectively and future-oriented.

Security at the highest level

The PLENTICORE MP also impresses with its numerous integrated safety features. An optional DC surge protector (Type 2) can be added directly to the device as a plug-in module. In the event of a lightning strike, this reliably protects the system – notification is automatically sent via the KOSTAL Solar Portal.

Smart sector coupling and seamless integration

With two LAN ports, four digital outputs, and an integrated Wi-Fi interface, the PLENTICORE MP offers excellent connectivity options for heat pumps, wall boxes, air conditioning systems, or heating elements. Thanks to Modbus TCP and SG Ready, it's also ideally suited for future smart home solutions.

Transparency and control – available everywhere

Free monitoring via the KOSTAL Solar Portal and the Solar App provides insight into energy flows, self-consumption, and self-sufficiency rates at any time. Users can keep an eye on their system at all times – securely, clearly, and in real time.

Intelligent shadow management included

Shading of individual modules? No problem. The PLENTICORE MP automatically detects the optimal operating point of each module string and ensures the best possible yields through dynamic MPP tracking – even with uneven solar radiation.

Compatible with the Consolinno HEMS – more efficient energy management

The KOSTAL PLENTICORE MP is fully compatible with the Consolinno HEMS.
This allows consumers in the household to be controlled intelligently, self-consumption to be optimized in a targeted manner, and PV surpluses to be used efficiently for heating or charging.
The integration also opens up access to dynamic electricity tariffs.

Everything included – for today and tomorrow

Whether used as a pure solar inverter, a hybrid solution, or with a storage connection, the PLENTICORE MP offers maximum versatility. Thanks to its modular power expansion, backup power capability, and comprehensive interfaces, it is ideally suited to the demands of modern energy supply.

You also benefit from the Smart Warranty:
5-year manufacturer's warranty plus an additional 5-year material warranty upon registration – for even more security and confidence in your PV system.
