PLENTICORE plus with storage

PLENTICORE plus from KOSTAL: the new standard for using solar power efficiently

The PLENTICORE plus converts solar energy into household electricity, stores it and then efficiently distributes it: it forms the heart of every system.

KOSTAL PLENTICORE plus: the most efficient hybrid inverter is suitable for every application

PLENTICORE plus: the name says it all. The three-phase hybrid inverter is always the right choice thanks to its various fields of application, be it for power generation with up to 3 MPP trackers or for additional storage of the self-generated energy.

It's not only possible to store solar power, but also the energy generated by a CHP. The battery can be connected immediately during installation or simply retrofitted later.

PLENTICORE plus. The original just got even better

The PLENTICORE plus hybrid inverter remains true to itself as an all-rounder: it is reliable, smart and easy to use.

Now in its second generation, the PLENTICORE plus is super smart: with integrated WLAN, KOSTAL’s original inverter now simplifies initial commissioning and monitoring. Two LAN interfaces allow several inverters to be networked in series as a "daisy chain".

The new second generation of the PLENTICORE plus now has four digital outputs – for more functions and a wider range of applications, e.g. for activating additional sources of consumption such as a heat pump, air conditioner or charging stations.

KOSTAL AutoUpdate: simple, safe and convenient

Thanks to its AutoUpdate function, your PLENTICORE inverter is always at the cutting edge of technology.

Once activated and set up, the inverters install each new software update fully automatically – so every functional enhancement, error rectification, compatibility and performance optimisation is always up to date.

All KOSTAL PLENTICORE inverters are supplied in the basic “manual software update” setting. If you want automatic updates, you must actively select this function on the inverter. Click here to discover how this works.

Benefits for you

Save on electricity costs

Low system costs

Protect the environment

The most efficient PV storage system for every application

Save on energy costs and protect the environment with the PLENTICORE plus in combination with the BYD battery box


Save money on acquisition costs with the PLENTICORE plus

In combination with the BYD battery box, PLENTICORE plus achieved top marks for system efficiency among PV storage systems in several performance classes. This was tested several times during the independent electricity storage inspection by HTW Berlin. Or proven.

Furthermore, as a hybrid inverter, the PLENTICORE plus offers optimum acquisition costs. Unlike with pure battery inverters, no additional devices are required because PLENTICORE plus takes over the energy management of the PV system and the battery at the same time. This means that acquisition costs can be reduced effectively.

Perfectly equipped for every application with the PLENTICORE plus hybrid inverter

The PLENTICORE plus hybrid inverter transfers the direct current generated to the storage system. It can process the current from the solar modules as well as other connected AC sources, such as a wind turbine.

PLENTICORE plus as a hybrid inverter: Generate and store solar power

The PLENTICORE plus as a hybrid inverter has three connections, one of which can be used as a battery input and the other two as PV inputs.

If there is a surplus of solar energy, it is temporarily stored in the battery and can be consumed at a later time. These measurement data are recorded by the KOSTAL Smart Energy Meter. The PLENTICORE plus performs battery management based on the measurement data. When the battery is fully charged, surplus solar power is fed into the public grid.

A high-voltage battery from leading manufacturers such as BYD, BMZ or Nilar can be connected during installation and activated using an activation code. 

Combination of photovoltaics and other AC energy sources 

Not only can the PLENTICORE plus hybrid inverter store electricity from solar modules, but it can also process energy from other connected AC sources, such as a wind turbine or an existing solar system.

If you already generate electricity from an AC energy source, you can expand this system with the PLENTICORE plus hybrid inverter and a battery. An AC energy source can be, for example, a combined heat and power unit, a cogeneration unit, a wind turbine or an existing solar system. This enables you to generate electricity sustainably, store it for later use and increase your self-consumption. 


Protect the environment

In addition to the potential for electricity cost savings, photovoltaic systems with efficient storage systems also contribute towards environmental protection. After all, a system's efficiency is decisive in the reduction of CO2 emissions.

By making the greatest possible use of self-generated solar power and dispensing with conventional power from fossil fuels, highly efficient PV storage systems can bring CO2 savings compared to a PV system without battery storage.

Product advantages

The PLENTICORE plus all-rounder is always the perfect solution

Our all-rounder takes PV power generation and energy use in the home to a whole new level. Self-learning shadow management delivers the best possible PV yields even in cloudy weather. And the 3 MPP trackers not only make retrofitting a PV storage unit child's play, they also means that roof alignment is no longer a big issue for generating PV energy.

  • Because it's compatible with batteries from various manufacturers, the right battery can be connected for every requirement. Furthermore, with up to 3 MPP trackers, the PLENTICORE plus offers the great advantage that the roof direction is no longer a big deal, meaning that each roof can be individually equipped with suitable solar modules depending on which way it is pointing.

    Thanks to additional, self-learning shadow management, the PV hybrid inverter PLENTICORE plus adapts quickly and individually to the conditions at the location. In this way, only those PV modules that aren't in the shade are triggered. This means that high yields can be achieved when generating energy, even when there's shade.

  • By integrating market-leading high-voltage batteries it's possible to optimise your self-consumption. This makes you less dependent on the electricity supplier and, therefore, safeguarded well against electricity price increases. 
    The PLENTICORE plus offers the perfect solution for all those who are still undecided about whether a battery is the right choice for them: if you just use it as a solar inverter with 2 MPP trackers to start with, you still have the option of retrofitting a battery later on without having to pay the full price immediately. If required, the activation code can be easily purchased later from the KOSTAL Solar webshop. This means that the PLENTICORE plus is perfectly equipped for new future technologies.
  • The PLENTICORE plus can also be integrated into a Smart Home via various interfaces, such as Modbus (TCP), to achieve even greater electricity cost reductions thanks to self-consumption optimisation. This is because intelligent consumption control allows consumers in the home, such as the washing machine, to be switched on when there is excess power, e.g. at lunchtime. This can be done automatically or at any time while out and about.
  • Owners of existing PV systems can also use the PLENTICORE plus not only to expand their existing systems but also to store energy from the old and new systems in the battery thanks to AC coupling. 
    A photovoltaic system can also be added to a CHP or wind turbine using the PLENTICORE plus and the energy produced from all generators can be stored in the battery. This means that the owner benefits from different power generators that complement each other perfectly and allow for maximum self-consumption. 
  • Due to its extended MPP range, the PLENTICORE plus is also ideally suited as a replacement device for old inverters. Due to ongoing technological advancements, new inverters have a higher efficiency, which means that they can achieve significantly higher yields when used as replacements. Thanks to its compact size, the hybrid inverter saves space and requires less room than previous generations of inverters. The technical properties of the PLENTICORE plus have also been designed very flexibly so that it can be easily and quickly connected to existing systems.

Good to know:

The PLENTICORE plus has repeatedly achieved top values in the SPI tests, especially in the higher power class from 10 kWp. Perfectly equipped for the future with KOSTAL!

KOSTAL inverters: perfectly equipped for the new generation of 400W modules

KOSTAL inverters compatible with 400W solar modules
