SINEXCEL Sirius 135K Certification Enables Resilient, Low‑Carbon Power for Unilever plc Factories

How certified grid-scale batteries change power for Unilever’s factories

SINEXCEL’s recent UL 1741 and IEEE 1547 certification for its Sirius 135K power conversion system creates a practical route for large manufacturers such as Unilever plc to accelerate on‑site decarbonisation and resilience projects across North America. The dual certification validates safety, grid interconnection and performance to regional standards, removing a major regulatory hurdle that has slowed adoption of industrial battery systems at food and consumer‑goods plants. For a global operator like Unilever, which runs energy‑intensive factories and distribution centres, certified systems simplify utility approvals and speed integration with local grid operators and microgrid controls.

The Sirius 135K’s grid‑forming capability and fast transfer response appeal to Unilever’s drive to reduce operational disruption and diesel usage at remote or critical sites. By enabling seamless parallel islanding of 100+ units and supporting “super‑hybrid” diesel‑battery setups, the technology helps manufacturers maintain production during outages while integrating larger shares of renewables. Its claimed greater than 98% full‑load efficiency and 100% unbalanced load handling reduce energy losses and improve power quality for sensitive manufacturing lines, which can lower production downtime and support Unilever’s targets for emissions reduction and energy cost management.

Operational advantages extend beyond technical performance to lifecycle economics and deployment speed that matter to Unilever’s capital planning. The Sirius 135K’s modular architecture, remote monitoring, firmware update capability and multi‑continent approvals cut balance‑of‑system costs and simplify maintenance planning across a dispersed portfolio of plants. These features allow Unilever to pilot batteries at representative sites, scale successful designs across regions and pursue utility partnership models — such as demand‑response or capacity services — that can offset the upfront investment and accelerate payback while meeting corporate sustainability goals.

Certification and technical specifics

SINEXCEL’s announcement highlights that the Sirius 135K already holds EN, AS and regional Thai approvals and now meets North American UL 1741 and IEEE 1547 standards for electrical safety, mechanical integrity and grid‑support functions. The unit offers IP66 protection, C5 corrosion resistance and harmonic adaptability to 25%, targeting harsh industrial environments and complex load profiles.

Commercial rollout and industry impact

The company positions the certified product for commercial and industrial portfolios, industrial campuses and critical infrastructure, aiming to speed pilots, grid trials and utility partnerships across North America. For consumer‑goods manufacturers such as Unilever, the development reduces regulatory friction and provides a tested option for resilient, low‑carbon power at scale.
