Въвеждане на използването на KSTAR ESS на практика

With the increasing demand for electricity and the instability of the power grid, modern energy storage systems are playing an increasingly important role. One of the leading manufacturers in this field is KSTAR, which offers efficient and technologically advanced solutions.

Our company is the official distributor of KSTAR for the Czech and Slovak Republics. We provide our clients with technical support, training at our headquarters in Znojmo or online. At the same time we have a training facility where you can try everything out.

ESS KAC50DP & BC100DE
The KSTAR KAC50DP-BC100DE cabinet was the first of its category to successfully pass the demanding certification tests according to PPDS conditions in accredited laboratories of the Brno University of Technology and will soon be certified.

It is the first certified inverter in the A2 category in the Czech Republic that will be able to be connected to the grid and that also complies with the subsidies.

Case study 1: Forestry nursery
One of the sites where the KSTAR KAC50DP-BC100DE system has been implemented is an area near the State Forests in Spala, Poland. At this site, power outages frequently occur, posing a significant risk to the operation of key equipment such as electronically controlled water pumps.

Thanks to the KSTAR inverter, the system enables efficient energy management and ensures availability during power outages. The STS100D transformer switch works seamlessly with the PV inverters and excess energy remains stored and ready for use in emergency situations.

Implemented solution:

• KAC50DP + BC100DE + STS100D
• ON-GRID + OFF-GRID
• Integration with photovoltaics to maximize self-consumption
• Diesel generator as additional security

Case study 2: Service centre
An automotive service center near Krakow required a solution that would provide uninterrupted power and ensure efficient management of surplus energy production and consumption.

The centre faced challenges with the constraints of buying power from PV. With the introduction of KSTAR ESS energy storage systems, the company was able to focus on its own consumption and effectively manage energy 24 hours a day. The new system minimizes operating costs and ensures a stable energy supply during production processes.

Solution implemented:

• 2x KAC50DP + 3x BC100DE + EMS01D (master controller)
• Operating mode: ON-GRID
• Integration with an existing PV system that previously supplied surplus energy back to the grid under unfavourable conditions
• Self-consumption priority, allowing the installation to maximise its own energy use
