ATMOCE Advances Absolute Safety and Ultimate LCOE with Three AC Innovations at Intersolar Europe 2026
ATMOCE is driving a new energy era through innovations in residential storage and solar generation. Built on Extra-Low Voltage (ELV) technology and next-generation microinverters, the system is designed to deliver 25 years of safe, reliable operation while achieving Ultimate LCOE.
At the heart of this ecosystem is the second-generation M-ELV Battery series, MS-8K-U PRO, jointly introduced with strategic partner E.ON. Powered by tier-one battery cells, the MS-8K-U PRO delivers 15,000 cycles, 51 MWh of lifetime energy throughput, and a 25-year warranty, setting a new benchmark for residential storage performance and lifecycle value. Built on ATMOCE’s proprietary ELV technology, the MS-8K-U PRO operates below 30 Vdc, redefining residential energy safety. The Easy Retrofit design
enables seamless integration with existing PV systems without inverter replacement or cable rewiring, significantly lowering upgrade barriers and accelerating residential storage adoption.
The 25-year residential platform is further supported by ATMOCE’s 2-in-1 microinverter series, ranging from 800 W to 1,200 W. Engineered with advanced semiconductor technology and DAB topology, the series delivers 98.2% peak efficiency and 97.7% EU efficiency, with up to a 25-year warranty and IP67-rated protection, ensuring dependable long-term performance.
Beyond industry-leading efficiency and reliability, the advanced DAB architecture enables intelligent bidirectional power transfer between the grid and PV modules. At Intersolar Europe 2026, ATMOCE and LONGi Solar jointly introduced the world’s first Microinverter-Driven Snow Removal Technology. Leveraging intelligent Grid-to-Module power transfer, the innovation helps reduce snow accumulation on PV modules, restore solar generation, and maximize energy yield under challenging winter conditions.
Reimagining C&I Storage with AC Architecture
ATMOCE also introduced BattBank, the world’s first Extra-Low Voltage AC Stackable C&I Battery, designed to deliver greater scalability, safety, and operational efficiency to commercial and industrial energy systems.
Engineered for efficiency, safety, and long-term reliability, BattBank is built on a modular AC architecture that enables fully scalable energy expansion. Each pack delivers 16 kWh of capacity, with 8 kVA rated output and 10 kVA maximum output. A single cluster supports up to seven packs, reaching up to 112 kWh of total capacity, 56 kVA of rated output, and 70 kVA maximum output—enabling flexible deployment and on-demand scalability across diverse commercial and industrial scenarios.
At the core of BattBank is an AC-based architecture, where each pack integrates an independent PCS and operates autonomously at the pack level. This enables automatic balancing between packs and ensures that performance degradation in one module does not affect system-level output stability, maintaining stable system performance over time.
This architecture enables true scalability, allowing systems to expand in line with energy demand while improving utilization efficiency, increasing system round-trip efficiency, reducing operational expenditure, and strengthening grid resilience.
Together, these innovations demonstrate how ATMOCE is advancing safer, smarter, and more efficient AC energy systems for both residential and commercial applications—bringing Absolute Safety and Ultimate LCOE to the next generation of distributed energy.
