For more than 100 years, the name KOSTAL has been synonymous with quality. The well-established German company made a name for itself as a reliable automotive supplier and expanded into other areas – especially solar technology. The company split off KOSTAL Solar Electric GmbH in 2006. Since then, KOSTAL inverters and solar power accessories have become an integral part of the industry, bringing environmentally friendly energy to homes and businesses.
The PLENTICORE and PIKO series of KOSTAL hybrid inverters are known for their energy efficiency and compatibility with solar batteries and photovoltaic systems from many manufacturers. Let's look at the KOSTAL inverter portfolio.
KOSTAL inverters – a success story
Long service life, efficiency and versatility characterize KOSTAL inverters. KOSTAL mainly sells two series of inverters: PLENTICORE for the residential and small commercial sector and PIKO for larger systems.
KOSTAL PLENTICORE:
The KOSTAL inverters in the PLENTICORE series are hybrid inverters for home systems. They convert AC solar power from photovoltaic systems into DC power for everyday use. KOSTAL inverters are also capable of feeding power into the power grid if the PV system produces excess energy. They have 2+1 MPP trackers for grid feed-in or for connecting additional equipment such as energy storage solutions, wall boxes or heat pumps. The output range of the KOSTAL inverters of the current PLENTICORE G2 generation stretches from 3-10 kW, with the new G3 generation offering an output of 15-20 kW and plenty of room for performance optimization in the PV system. This means that KOSTAL inverters from the PLENTICORE series are perfectly suited to working with modern solar panel technology.
Versatility is their strength: thanks to the interfaces for LAN, Wi-Fi, RS485 and Modbus RTU, KOSTAL inverters are compatible with a wide range of solar technology: direct and efficient integration of renewable energies in one inverter.
KOSTAL PIKO:
Die KOSTAL inverter PIKO CI with 4 MPP trackers is suited for large and commercial systems. They are available in versions between 30 and 66 kW. With their high energy efficiency, KOSTAL PICO CI inverters are also a good choice for large energy storage solutions, such as off-grid systems.
KOSTAL PLENTICORE G3 – new, flexible, powerful
The new top performer among the KOSTAL inverters is the KOSTAL PLENTICORE G3 L with an output of 15-20 kW. The 3rd generation of the PLENTICORE series fills the gap between the PLENTICORE G2 and PLENTICORE PICO – e.g. in the small business sector. KOSTAL is also introducing the KOSTAL PLENTICOINs together with the PLENTICORE G3 L. This digital voucher gives you the opportunity to use upgrades such as an increase in performance, upgrading to a hybrid inverter or connecting new loads directly with just a few clicks. This allows you to set up the KOSTAL inverter exactly to the specific requirements on site without having to change the hardware. You can find everything about KOSTAL PLENTICOIN here.
It is the first KOSTAL inverter to have an emergency power function. This can be activated via the KOSTAL BackUp Switch. You can enhance the integrated overvoltage protection with the KOSTAL G3 DC overvoltage protection.
The KOSTAL PLENTICORE G3 L is also SG-Ready (Smart Grid Ready). This means it can work together with intelligent power grids, control consumers in a targeted manner and optimize the grid feed-in.
KOSTAL will expand the new G3 generation in 2024 to include models in power classes M and S.
Application areas for KOSTAL inverters
The KOSTAL PLENTICORE, PLENTICORE G3 L and PICO inverters are suitable for all standard applications. They offer the best way to increase the energy self-sufficiency of a household – a KOSTAL inverter, together with a BYD storage system, took 5th place in the 2024 electricity storage inspection at HTW Berlin.
If you want to supply a commercial facility or an apartment building with sustainable energy, the new KOSTAL PLENTICORE G3 is a good choice: it can process up to 20 kW of solar power with power upgrades and with KOSTAL PLENTICOIN you can adapt it to such projects easily.
KOSTAL serves large projects with the PIKO CI inverter. With high energy efficiency, 4 MPPT and a capacity of up to 66 kW, it is ideally suited for farms or ground-mounted systems.
