The KAC50DP/BC100DE. It fulfils many of the expectations of current investments throughout Europe and has the corresponding certificates and guarantees. It is a medium-sized energy storage system for use in systems from 50 kW up to 1,000 kW. It fulfils the requirements of both smaller and larger systems.
Safe&Reliable
Simple and user-friendly
The finished unit consists of a battery cabinet with a footprint of 1.1 x 1.1 metres and a height of approx. 2.4 metres. The entire unit is adapted and designed for outdoor use.
Integrated EMS with integrated control interface, equipped with BMS with 1+1 redundancy design
Automatic and fast-acting fire extinguishing system at both module and cabinet level
Module level
Each module is equipped with efficient, environmentally friendly aerosol that is released when the sensor detects unusual temperatures to minimise the effects of fires.
Cabinet level
The two corners of the battery cabinet are also placed in the aerosol, this dual fire extinguishing design makes the entire ESS safer.
It is important to emphasise that this is a very safe solution. In addition to constantly monitoring the status of all batteries, each module is equipped with its own extinguishing spray. There are also additional extinguishing agent sprays in the upper and lower sections. In the event of an emergency, the device switches off automatically.
Highly efficient temperature and humidity management system for better battery performance
• Intelligent cooling with Tier 1 industry air conditioning system
• Compact design with wall mounting
• Optimised wind path for high cooling efficiency and low temperature difference (max.<5 °C).
• Closed cabinet for better HAVC performance
Thanks to the built-in air conditioning and the insulation of the cabinet, the batteries always operate at the optimum temperature. In addition, the system is equipped with a lightweight and easy-to-operate air conditioning unit and not with a complicated and heavy liquid cooling system, which some manufacturers cite as an advantage. Kstar proves with thermal images that the cooling provided by the air conditioning system is sufficiently effective. The temperature difference between the batteries is about 1 degree Celsius.
We can connect up to 20 devices and achieve an output of 1 MW and a capacity of up to 4 MWh.
Off-grid installations of 100 kW and 250 kW are possible with the STS cabinet. The STS cabinet offers the option of connecting a power generator.
ToU, peak shaving, self-consumption enabled by built-in local controller
Strategy: PV generation primarily covers the demand of consumers and the surplus PV power is stored for later use.
Purpose: To reduce the electricity bill by minimising energy consumption from the grid
Strategy: When the power drawn from the grid is outside the peak/low point range, the battery starts discharging/charging.
Purpose: Avoid additional costs due to extremely high demand and make optimum use of the electricity capacity contractually agreed with the DSO/DSO.
ToU, Peak shaving, Self-consumption enabled by built-in local controller
Strategy: Preset a times chedule for the system to charge and discharge with selectable timer and power ratings
Purpose: Make sensible use of electricity arbitrage to minimise the electricity price per unit
Strategy: PV generation and grid cover battery charging needs; battery only discharges after grid failure.
Purpose: Ensure longer backup operating time and a reliable power source
This device can be assembled in just three hours thanks to almost 100 per cent prefabrication at the factory. At the installation site, the 50 kW hybrid inverter is simply mounted and the supplied cables are connected. Now just connect the AC and DC cables to the inverter and the device is ready for operation.
