Modular

The SieStar battery energy systems are prepared for expansion within the existing housing. The system can expand from one to multiple units, allowing storage capacity to grow with your business needs and rising energy requirements.

Integrated EMS

The SieStar Energy Management System (EMS) manages energy flows behind the meter and regulates consumption and feed-in to the grid in accordance with the contracted capacity. It offers functions such as peak shaving, load shifting, emergency power supply, smart charging, (thermal) energy buffering and energy trading.

Safety

The systems are built in accordance with PGS37.1 and offer 60 minutes of fire resistance. Equipped with a two-stage fire alarm system with PAC transmission and remote emergency stop, they are inaccessible and switch off automatically when the service door is opened.

LiFePO4 batteries

SieStar offers up to 10 years or 6,000 cycles warranty. The LFP battery cells are assembled in Terneuzen and offer optimal stability and energy transfer. Benefits include a long service life, fire safety and active balancing for 15% longer service life.
