More power for your monophase PV system

Now with the PLENTICORE MP

Repowering of monophase PV systems

More power, more options - with the PLENTICORE MP

Many photovoltaic systems with a single-phase connection have been providing faithful service for over ten years. However, the inverter in particular - the centrepiece of the system - eventually reaches its limits: decreasing efficiency, increasing probability of failure, lack of connection options for modern components such as battery storage or energy management systems.

The PLENTICORE MP from KOSTAL is now the ideal solution for repowering smaller, single-phase PV systems. Compact, powerful and future-proof, it brings new energy to your existing solar system - without the need for costly conversions.

Why repowering is also worthwhile for single-phase systems

Eliminate technical weaknesses

Old inverters often work with lower efficiency and do not have the capabilities of modern devices. If the inverter fails, the entire electricity production comes to a standstill. Repowering increases your yield and ensures that your system will continue to function reliably for many years to come.

Protect your investment

A PV system is a long-term investment. By replacing the inverter, you ensure that your system remains state of the art - and that you get the maximum benefit from your investment.

More yield with the same space

A modern inverter like the PLENTICORE MP gets more energy out of every ray of sunshine. The higher efficiency is directly reflected in your electricity bill.

Why stay single-phase? - Efficiency without conversion

Many smaller PV systems up to 10 kWp are connected to the grid with a single phase. There is no legal obligation to switch to three phases for this system size. This means that you can remain single-phase when repowering - without costly adjustments to the house connection.

Your advantage: The PLENTICORE MP replaces the old inverter 1:1. Installation is uncomplicated, quick and causes minimal downtime.

Retrofit the storage system at any time - thanks to the disconnectable battery input

A decisive advantage of the PLENTICORE MP is its flexibility in terms of storage integration. You don't have to decide in favour of a battery storage system straight away.

Enabled battery input: Simply activate the storage function when it suits you economically and technically
High compatibility: The PLENTICORE MP works with leading high-voltage batteries such as BYD or Varta
More independence: With storage, you can increase your self-consumption and reduce your electricity costs even further
