A clever combination of photovoltaics and heat

This is the idealway to network KOSTAL inverters with a heat pump from NIBE

In terms of sector coupling and as part of a successful energy transition, KOSTAL is constantly expanding its network with renowned partners. KOSTAL's new partnership with the Swedish heat pump specialist NIBE enables operators of photovoltaic systems to enjoy a combination of inverter and heat pump that functions smoothly.  

The course is set for sustainability

A heat pump is an energy-efficient heating system that uses ambient heat to heat a building. A photovoltaic system is the perfect complement to this, because a large proportion of the electrical energy required comes directly from your own roof. Using renewable energies can significantly reduce the operating costs of a heat pump.


Smart combination of inverter and heat pump

The PLENTICORE hybrid inverter from KOSTAL and the S series heat pump from NIBE can be easily connected via WLAN or a network for smooth communication. The heat pump software communicates with the hybrid inverter via a standardised Modbus/TCP interface according to the SunSpec protocol. In this way, the available power of the PV system is balanced with the power required by the heat pump so that the available electricity can be put to ideal use.

NIBE's S series heat pumps

NIBE heat pumps from the S series are equipped with innovative technology that enables high performance and energy efficiency. They use what is known as inverter technology, which enables them to automatically adapt their output to the building's requirements. This maximises the efficiency of the heat pump and minimises energy consumption. In addition, the heat pumps in this series can be used to both heat and cool a building.

They are also equipped with a number of features that help to extend the life of the heat pump and optimise its performance.

The PLENTICORE plus hybrid inverter

The PLENTICORE plus as a hybrid inverter is the perfect all-round solution for all conceivable system configurations and offers a simple connection to the NIBE heat pump. As a true all-rounder, the PLENTICORE plus has a stand-alone output of between 3 kW and 10 kW and achieves even higher outputs when two or more devices are interconnected. It provides dynamic regulation, delivering the greatest possible amount of self-produced electricity at the right time.

An important step forwards

Home owners focusing on sustainability, scalability and independence can be sure they are making the right choice with products from KOSTAL and NIBE. The high-quality products from Germany and Sweden allow them to be independent of volatile energy prices. Thanks to smooth compatibility and user-friendly control of the system components between KOSTAL and NIBE, nothing stands in the way of sustainable and carefree heating.
