More power and yield with KOSTAL inverters

Intelligent shadow management for ideal PV generation, even in cloudy conditions, and optimal roof utilisation with up to 3 MPP trackers. With KOSTAL inverters, you can make the best possible use of your PV system's potential, regardless of the roof direction. For the most efficient use of energy.

But let's start at the beginning: What does MPP even mean?
Every photovoltaic system has what's called a Maximum Power Point (MPP). This is the point at which a solar module achieves its highest or maximum output. The task of MPP tracking is to set this maximum performance point reliably and accurately at all times, according to the conditions.

The three-phase PV inverters from KOSTAL not only constantly keep the solar modules at the maximum power point (MPP), but also have an intelligent shadow management system. This means that, despite there being some potential shade from a chimney or tree for example, the KOSTAL PV inverter adjusts the relevant module string to its optimum performance and ensures an ideal yield.

Why complicate things unnecessarily?
KOSTAL inverters have everything that a PV system needs for efficient power generation. Thanks to KOSTAL shadow management, most applications don't require complicated "module optimisation" installations under every module. Advantage for the customer: Near perfect energy production and low installation costs. Any potential maintenance and repair costs are also low as no electronic components are installed in the hot roof area below the module. Our goal is to make PV power generation simple and efficient. Just smart.

Easy access to inverter consumption data in the portal
Our inverters are equipped with an interface to the solar portal as standard. This means that the photovoltaic system's latest consumption and performance data can be viewed there at any time. To monitor the system's yield in the best possible way. Alongside system data.

Retrofitting a PV storage unit? Easy!
Our hybrid inverters offer the option of connecting a PV storage unit later when the time is right for you. Still not sure whether you will always use the energy immediately or want to store it? A hybrid inverter like the PLENTICORE plus can also be used without battery storage, which can be easily retrofitted later on, when the need arises. You only have to pay for this if the 'Storage use“ option is enabled for the inverter.

Intelligent use of solar power thanks to PV inverters from KOSTAL

As well as efficiently generating photovoltaic energy, KOSTAL inverters can also ensure that the electricity generated can be used intelligently in the home. Thanks to innovative technologies, the home can be developed into a Smart Home, for example.

KOSTAL's three-phase PV inverters provide various communication interfaces for this purpose, including EEBus, SunSpec or ModBus. With these, the electricity consumers in the house, for example a heat pump, can be supplied with solar energy when it's available. This process doesn't need to be controlled manually because the inverter and the consumer communicate automatically.

Why does it matter? Integrating them into a Smart Home can increase the amount of solar power that's consumed within the home. As a result, less electricity has to be purchased from the external electricity supplier, meaning that electricity costs can be reduced.

Heat pumps, air conditioners and heating elements can also be supplied with the self-generated solar power by connecting to a relay output integrated in the PV inverter. This further optimises the self-consumption of the energy.

In order to consume even more electricity yourself, a storage unit can be added to the PV system. This allows the solar power to be buffered during the day and consumed in the evening after sunset. Energy can be stored in various ways with KOSTAL hybrid inverters. Choosing a hybrid inverter is particularly worthwhile when building a new solar system or replacing an existing PV inverter.

In existing PV systems, the storage option can be easily retrofitted thanks to the KOSTAL battery inverter. In addition to the permanently installed battery, solar power can also be stored with a mobile storage unit, i.e. an electric vehicle, or in a cloud solution.

Every photovoltaic system requires an inverter

This is the only way that electricity generated by the sun can be fed into the public grid or consumed by electrical appliances in the house itself.

But why is that? A PV system's solar modules generate direct current. However, the public power grid, as well as almost all common electronic appliances in the home, are designed for alternating current. Therefore, the PV inverter's job is to convert the direct current from the solar modules into alternating current. This conversion is necessary to make solar power usable or "compatible". Therefore, as an essential component in every PV system, the inverter is often called the heart of the solar system.

Other PV inverter functions

But the inverter not only acts as a current transformer. The innovative PV inverters from KOSTAL offer even more possibilities. They include:

• Optimum energy yield from the PV system
• A wide range of monitoring functions for your electricity consumption and production
• Various grid services to stabilise the electricity supply grid
