Introducing the parallel connection options for KSTAR

1. 9. 2025

Founded in 1993, KSTAR is one of the leaders in electronics and new energy. The company has over 4,200 employees, more than 630 patents and offers solutions that use the latest technology and a focus on reliability.

Their products are designed for those who seek reliability and simplicity in everyday operation. They are ideal for demanding users who appreciate high-quality workmanship and easy installation.

Thanks to CATL's world-class battery cells and intelligent design, KSTAR solutions offer exceptional safety, efficiency and flexibility. They are definitely the right choice not only for energy management in the commercial sector.


Our company, Green Energy Trading, is an official distributor and can therefore provide all customer service and technical support to our clients.

We organise regular training sessions at our company, hold webinars and have a training facility where you can try everything out.

ESS KAC50DP & BC197DE

Safety and reliability

  • CATL LFP battery cell
  • Double fire protection system design
  • Redundant 1+1 design

Simplicity and user-friendliness

  • Pre-installed at the factory
  • For easy on-site installation
  • Integrated EMS, suitable for a variety of applications
  • Hassle-free, cloud-based control

  • Redundant 1+1 design
  • Better cooperation between BMS and EMS
  • User-friendly EMS design with multiple operating modes
  • 7-inch EMS screen with easy operation
  • More reliable communication with less risk of external influences
  • Provides a third party communication interface for higher level monitoring and control

KAC50DP

  • KSTAR 50kW hybrid inverter
  • Maximum efficiency up to 97.5%.
  • IP65 protection
  • Operating temperature range -25~60℃ (>45℃ Power reduction)

BC197DE

  • KSTAR 197 kWh outdoor battery cabinet
  • LFP battery type
  • Battery module capacity 17.92 kWh
  • Number of modules 11
  • Total battery capacity 197 kWh
  • Rated voltage 704 V
  • Operating voltage range 616 ~ 792 V
  • Charging/discharging speed Max. 0,5 C

EMS01D master control unit

  • Optimised energy management and cost reduction
  • Real-time monitoring with alarm function for increased system safety.
  • Seamless integration with existing energy infrastructure for dynamic power management
  • Flexible application scenarios, tailored to different industrial load profiles.

The implementation of the EMS01D system provides KSTAR battery storage systems with extended control options and more efficient energy management, resulting in cost optimisation.


System connection: parallel mains connection

Below we present three possible parallel wiring scenarios according to the required power.

500- 985 kW


800- 1576 kW


1000- 1970 kW

* If the customer wants to use a third-party EMS, he must replace the EMS01D with his third-party EMS; if the customer wants to use only the KSTAR monitoring system, he can use the EMS01D.

* * Self-power, peak shaving, backflow prevention and valley filling modes require the purchase of a meter. Time-of-use and battery priority modes do not require the use of a meter.
