Reference systems with inverters, wallboxes and energy meters from KOSTAL

Craft business relies on several PLENTICORE

Antoni Izquierdo Gourmet, SL, a craft business that produces sofritos, gourmet preserves and products made from the valuable Palamós shrimp, has inaugurated the first plant in Spain to combine KOSTAL inverters with ZYC Energy batteries.

Empordà Solar (a certified KOSTAL installer) was able to optimise the solutions offered by KOSTAL so that the company can cover a large part of its energy needs with clean electricity.

Empordà Solar used 14 SIMPO HV battery modules from ZYC Energy to achieve an energy capacity of 44.8 kWh.

Redevelopment of an industrial site with PIKO CI

The Italian company EPC Elettronica Italia has built a photovoltaic system with bifacial modules on a disused site in the province of Lecce. The modules are connected to 20 PIKO CI inverters from KOSTAL, each with an output of 50 kW. The system has an output of 1 MWp and the energy generated is sold to the grid. Elettronica Italia Service was responsible for the installation and KOSTAL inverters were chosen for their high efficiency and optimal energy production.

The inverters support currents of up to 18 amps and enable optimal configuration of the strings. The plant is one of the first in Italy to be installed with such a large number of PIKO CI inverters.

More self-sufficiency in residential area with PIKO CI

The BBK Group from Trelleborg is installing PV systems on 15 buildings with a total of 540 apartments. A total of 2048 solar panels are being used for this large-scale project. It is expected to produce 550,000 kWh of electricity per year.

This requires reliable inverters to supply the residents with electricity. Daniel Ohlin of the BKK Group relies on manufacturers that meet the highest standards and fulfil his expectations in terms of durability. After trying out inverters from various brands, the PIKO CI proved to be the most efficient. The fact that KOSTAL's research and development is based in Germany and that KOSTAL offers technical customer service within the EU also led Daniel to choose the PIKO CI.

A future-proof economy with PLENTICORE

As early as 2010, the daycare centre in Steinberg, Saxony, was already using photovoltaics. The 25-kilowatt peak photovoltaic system was originally installed to feed into the grid, but in the future it is to be supplemented by a storage system to supply the daycare centre with energy in the low-sunshine morning hours.

The centrepiece is three PLENTICORE units, which efficiently convert solar energy but can also be easily expanded for future energy storage. KOSTAL is constantly increasing the number of compatible battery storage units for the PLENTICORE, so that there is a suitable selection for every requirement. And with AutoUpdate, the software is always up to date.

High degree of self-sufficiency for food manufacturer with the PIKO CI

The PIKO CI commercial inverter is KOSTAL's robust power pack and the ideal solution for small and medium-sized commercial projects. Electrical engineer Nick Varnas is also convinced by the high quality of KOSTAL products, which is why he chose the PIKO CI.

Thanks to daisy chain communication, several inverters can be used. This makes it possible to generate 1,150 MWh per year, enabling the Greek juice producer Hellenic Juices SA to achieve a self-sufficiency rate of 75%. Based on the electricity price at the time of installation, the system will pay for itself in 2.5 years. Installers will also be pleased, as the PIKO CI is easy to initialise, either on site or from the office, using an app or PC software.

Private energy revolution in a two-family house with two PLENTICORE inverters

The municipality of Inzlingen, near Basel, is where Siegbert Wiedmar lives. His two-family house is an ideal example of the ‘KOSTAL Doppelpower’ principle. This means that two PLENTICORE plus units are operated in a device network, in this case with 10 kW and 5.5 kW of power.

The ‘Smart AC-Link’ function also allows all the energy generated to be stored. Mr Wiedmar opted for a BYD storage unit with 12.8 kilowatt hours. The result is impressive, with both households achieving 99% self-sufficiency in the first four of eight months. Further information about the system can be found in the interview.

Pure efficiency with the PIKO CI commercial inverter

My-PV offers functional and innovative solutions for home automation powered by solar energy. My-PV also relies on the intelligent use of solar energy for its own company building. The modules, which are installed over the entire surface of the unmistakable company building, deliver 100 kilowatts of peak PV power. The PIKO CI commercial inverter series is part of the my-PV energy concept.

Thanks to its robust construction and IP65 protection class, the devices could be easily installed on the outside of the building. The PIKO CI works in a tested temperature range of -25°C to +60°C, thus providing the best conditions for safe operation.

Countering volatile electricity prices with the PIKO CI

EZEQUIEL, a food producer in Castile, operates many cold stores and drying rooms. Due to its high energy requirements, a volatile electricity price can negatively affect the company's competitiveness. For this reason, an efficient PV system was needed. At the heart of the system are eight PIKO CI 60 units connected in series to convert the energy generated by the 613 kWp solar panels into usable electricity.

The PIKO CI offered EZEQUIEL the best combination of price, performance and flexibility. It is also safe and robust. And should battery storage be purchased in the future, the PIKO CI has sufficient connections when combined with the PLENTICORE BI battery inverter.

Reducing electricity costs in agriculture with the PIKO CI

Milking robots, milk processing plants with cooling and a groundwater treatment plant are real power guzzlers. To reduce his electricity costs, farmer Kuhn decided to use the PIKO CI 30 in conjunction with a BYD battery storage system with a net storage capacity of 22 kilowatt hours.

Mr Kuhn chose the products of the long-established German company based on his solar installer's years of experience with KOSTAL products. The IP65 housing is dust and water protected. This makes the PIKO CI the ideal choice for agricultural use. And with the associated app, all relevant energy values can be read quickly and easily at any time.
