How can energy storage system be used? ✨
20. 6. 2025
In connection with the development of solar energy in recent years, the topic of battery storage has become increasingly popular.
In general, ESS (energy storage systems) are used to store energy. However, there are various scenarios for storing and subsequently releasing energy, and each requires a slightly different configuration of battery storage, software, and wiring.
Let's take a look at them together.
Strategy: PV generation meets the demand of the loads in priority, and the excessive PV power will be stored for later use.
Purpose: Cut electricity bill by minimizing the energy consumption from the grid.
Strategy: When the power extracted from the grid falls outside the peak/valley range, the battery starts to discharge/charge.
Purpose: Avoid extra charge caused by extreme high demand and make good use of power capacity contracted with DNO/DSO.
Strategy: Preset a time schedule for the system to charge and discharge with selectable time range and power ratings
Purpose: Make good use of electricity arbitrage to minimize the unit electricity price
Strategy: PV generation and Grid meet the demand of battery charging; Battery discharges only after grid failure.
Purpose: Ensure longer backup operation time and reliable power source.

KSTAR residential solutions
The KSTAR BluE-S Series residential energy storage system is a state-of-the-art all-in-one three-phase energy storage product. It provides a safe, smart, and highly efficient solution for residential installations. This AIO solution uses CATL battery cells.
The three-phase hybrid inverter offers an intelligent modular design and online monitoring via an app. It also allows for time-based tariff programming.
For example, charging at night during off-peak hours and use during expensive peak hours in the afternoon.
Low maintenance costs and easy installation are major advantages.
KSTAR commercial solutions
KSTAR BluPulse commercial energy storage systems are characterized by safety, reliability, and user-friendliness.
The KSTAR ESS KAC50DP-BC100DE and 2x KAC50DP-BC197DE outdoor solutions are designed for small to medium-sized energy storage applications and microgrid projects in the commercial and industrial sectors.
Integrated with the CATL LFP battery solution, they ensure safe energy storage and control of energy consumption.
They offer the possibility of scaling the storage capacity up to 2 MWh and also several basic operating modes (own consumption, peak load control, backup).
The KSTAR KAC50DP-BC100DE cabinet has been tested at Brno University of Technology and has obtained a key certificate. It is one of the first certified inverters in the A2 three-phase hybrid 50 kW category in the Czech Republic. It can be connected to the grid and is eligible for subsidies.
