Rimac Energy Unveils SineStack, Intended to Enter into Strategic Partnership with ENNA – Rimac Newsroom

With the establishment of SineStack, Rimac Energy has also announced its intention to cooperate with ENNA, a leading investor and energy company in Croatia. The companies intend to deploy Rimac Energy’s SineStacks to ENNA grid-connected renewable energy projects and beyond. The first pilot project will be delivered to the ENNA sites in 2024, enabling both companies to refine the project implementation plans.

SineStack Product Description

SineStack is a technological innovation. At its core is a highly distributed and integrated power conversion system controlled by highly innovative software that enables:

Industry leading Standardized Cost of Storage – system life of up to 12,000 cycles, >92% Round Trip Efficiency, and less than 5°C total rack temperature through liquid cooling.

Class Leadership Score – the very compact design integrates the Power Conversion System (PCS) with the battery, eliminating the need for external converters, reducing additional space requirements and increasing energy per square meter.

Deep Insights for enhanced performance – the unique electrical architecture and internal control software draw all the energy from each cell, reducing the energy that cannot be obtained during operation. A modern cell life enhancer ensures that cells are stressed according to their health, providing up to 30% longer life.

More Safe – security built into hardware, software and cloud systems, supported by extensive simulation and testing. Combined with LFP chemistry, SineStack provides superior protection against unexpected failures, as well as the ability to perform a variety of probes without system downtime.

Cost-effective Energy Efficiency Improvement – The SineStack Integrated Power Conversion System allows customers to add up to 790 kWh blocks at a time without the need for a converter change or add-on. AC coupling comes as standard, providing an easy and cost-effective way to add capacity when the time comes.

Made in Europe

SineStack is a mission to meet the urgent needs of the energy transition in Europe by delivering a battery energy storage system developed in Europe. By championing local production and sustainability, Rimac Energy aims to play a key role in advancing environmental responsibility and expanding access to sustainable energy solutions, setting the stage for a cleaner, lower and more sustainable future across the continent. Rimac Energy’s planned partnership with ENNA plays a key role in accelerating sustainable energy initiatives across Southern and Eastern Europe and beyond, with Croatia serving as a launch pad for this transformation.
