Lion Energy Debuts FEOC-Compliant, U.S.-Ready EMS-C Platform for LionESS Systems

Lion Energy Debuts FEOC-Compliant, U.S.-Ready EMS-C Platform for LionESS Systems at Intersolar & Energy Storage North America Event in San Diego, CA

Lion Energy today announced that its EMS-C™ Energy Management System fully aligns with the evolving Foreign Entity of Concern (FEOC) “Effective Control” requirements. This achievement highlights the company's steadfast dedication to safeguarding domestic energy infrastructure and delivering protected, sovereign-controlled energy solutions.

With increasing regulatory focus on system control, remote access privileges, firmware management, and data routing security, the EMS-C™ platform was designed from the outset to surpass these emerging standards.

Engineered for Secure Domestic Control The EMS-C™ provides comprehensive protection through:

• Proprietary Lion Energy hardware

• Fully controlled firmware architecture

• Secure, restricted access pathways

• Domestically governed software ecosystems

• Robust, protected data management frameworks

This integrated approach ensures that ultimate system control, update authority, and access permissions remain entirely within a U.S.-based, domestically managed environment.

FEOC Compliance Assurance

Lion Energy's EMS-C™ platform exceeds current FEOC “Effective Control” guidelines, including those outlined in recent Treasury and IRS notices (such as Notice 2026-15). By maintaining exclusive domestic ownership and governance over hardware, firmware, software, and data pathways, the system avoids any payments, contracts, or IP licensing that could confer effective control to a specified foreign entity or prohibited foreign entity. This design prevents disqualification from relevant clean energy tax credits under sections like 45Y, 48E, and 45X, ensuring full eligibility for customers seeking compliant, secure energy storage solutions amid tightening domestic content and control requirements.

“True energy independence goes beyond generation and storage, it requires complete control over our critical infrastructure,” said Tyler Hortin, CEO of Lion Energy. “From the beginning, the EMS-C™ platform was built with long-term domestic security and regulatory compliance as foundational priorities.”

Sanctuary 2 and Sanctuary 3 – Powered by EMS-C™ and Available June 2026

Lion Energy is excited to announce that our next-generation Sanctuary 2 and Sanctuary 3 energy storage systems will start shipping in June 2026. These systems are fully integrated with the advanced EMS-C™ Energy Management System, which is already compliant with key standards.

Sanctuary 2 and Sanctuary 3 are engineered to meet FEOC restrictions and Domestic Content requirements. These newly released systems are expected to qualify for relevant incentives once compliance milestones are finalized. Lion Energy is now accepting pre-orders for this next-generation ESS equipment, with compliant units scheduled for delivery beginning June 2026. Secure your system today to ensure delivery starting in June 2026.

The Sanctuary 2 (residential-focused, indoor design) features:

• A powerful 12 kW hybrid interactive inverter for seamless grid support, solar integration, and reliable home backup power

• Scalable 14.3–42.9 kWh LiFePO4 battery capacity (expandable with additional modules) to meet diverse household needs

• High-efficiency, silent operation (89% single-cycle round-trip efficiency) using safe, maintenance-free lithium iron phosphate technology, no fumes, no noise

The Sanctuary 3 (designed for outdoor residential and light commercial scalability) includes:

• High-output 18 kW inverter per unit (scalable up to 48 kW in parallel configurations) for whole-home or business backup and heavy loads

• Extensive 14.3–171.6 kWh expandable capacity using 14.3 kWh LiFePO4 battery modules to handle demanding energy requirements

• Advanced grid-responsive and compliant architecture (UL 9540, IEEE 1547 certified) with NEMA 3R/IP65 protection for dependable performance in varied environments

Both systems also deliver:

• Seamless EMS-C™ integration for intelligent energy orchestration

• Flexible configurations for residential and commercial applications

• Grid-responsive capabilities that enhance reliability and efficiency including advanced support for utility programs, demand response, and seamless participation in Virtual Power Plants (VPPs) through IEEE 2030.5-compliant communications and smart dispatch features

• Inherently compliant, domestic-focused design

• Strong positioning for VPP ecosystems, where Sanctuary systems can aggregate with others to provide grid services, stabilize the network, optimize energy use, and unlock potential revenue or incentives for owners leveraging the secure, domestically governed EMS-C platform for reliable, regulation-ready performance

As demand grows for secure, regulation-ready energy storage solutions that go beyond backup to active grid participation, interested customers are encouraged to place early reservations for priority access.

Leading the Next Era of U.S. Energy Infrastructure

With strengthening domestic content requirements and evolving “Effective Control” interpretations, Lion Energy is positioned to provide energy storage solutions that are:

• Secure

• Fully compliant

• Highly scalable

• Governed domestically

• Ideally suited for the expanding VPP landscape, empowering homeowners and businesses to contribute to a resilient, decentralized grid while maximizing value

Energy independence is not just about capacity, it's about control and increasingly, about contribution.
