Explore our elite range of UL and CE certified energy storage products engineered for seamless grid integration.
Modern electrical grids demand unparalleled flexibility. In the transition toward decarbonization, AC coupled battery storage systems have emerged as the premier design paradigm for expanding existing solar installations and handling complex microgrid topologies. Unlike DC-coupled architectures which link batteries directly to the solar array's PV side, AC-coupled systems interface on the alternating current side of the distribution network. This subtle difference is game-changing.
AC coupling enables grid-tied photovoltaic inverters and battery storage inverters to operate independently. If a site already has an operating PV setup, an AC-coupled battery system can be added seamlessly without altering the pre-existing arrays, wiring, or certifications. This reduces overall permitting times, prevents generation losses, and lowers hardware deployment friction. In utility-scale, commercial & industrial (C&I), and smart residential zones, the versatility of AC coupling supports dynamic load tracking, precise frequency regulation, and microgrid islanding capability.
"By separating the photovoltaic generation cycle from the battery storage circuit, AC-coupled topology yields high operational redundancy. A fault on the PV inverter does not compromise the energy storage dispatch, nor does a battery BMS warning interrupt solar feed-in, guaranteeing maximum reliability for commercial installations."
Zero alteration to existing solar arrays. Simply integrate the energy storage system to the AC busbar. Highly cost-effective for retrofitting established utility and C&I sites.
Charge at off-peak grid pricing, discharge during high-demand surges. AC systems intelligently adjust charge/discharge thresholds in milliseconds.
Supports grid-forming, black start, and islanding capabilities to protect critical processing nodes, manufacturing systems, and data center structures from blackouts.
Established in 2019 and headquartered in the high-tech hub of Xiamen, China, Elemro Energy has grown to become a leading market innovator in electrical products and advanced new energy solutions. We consolidate R&D, structural design, global production networks, and comprehensive B2B supply logistics.
Our business model focuses on bringing elite Chinese battery cell technology and automated industrial designs to global procurement divisions. Elemro's high-voltage stackable, low-voltage wall-mounted, and containerized battery solutions have been deployed by over 250 enterprise clients globally, spanning Europe, Southeast Asia, the Middle East, Africa, and the Americas. By continuously expanding our technical capabilities, our annual turnover reached over 50 million USD in 2023. We provide cleaner energy for a greener world.
ELEMRO Energy's manufacturing plants employ state-of-the-art Industry 4.0 technologies, ensuring consistent cell performance and long-term lifespan safety. Located near major trade infrastructure hubs, our production facilities are optimized to deliver scale, durability, and cost-efficiency.
We work exclusively with Tier-1 LFP cell providers. Each cell undergoes thorough testing (internal resistance, voltage variance, cell capacity) before module assembly.
Laser welding and sorting processes are entirely automated, avoiding degradation-accelerating impurities and achieving unmatched thermal consistency.
Our proprietary Battery Management System tracks thermal and voltage changes at the cell level, protecting systems from short circuits, overcharging, and thermal runaway.
Logistical Advantage: Headquartered in the coastal city of Xiamen, ELEMRO benefits from direct, deep-water port access. Our partnerships with top global shipping companies ensure optimized shipping rates and fast dispatch paths to Europe, Australia, and the Americas.
Start a green and convenient life with Elemro Energy solutions designed for high reliability.
Next-generation solar glass panels engineered for building-integrated photovoltaics (BIPV), maximizing energy generation on vertical facades.
Pre-engineered, climate-controlled container systems featuring complete liquid or air cooling, fire suppression systems, and integrated megawatt-class BMS.
Structural solar carports paired with AC-coupled battery arrays for fleet EV charging, demand control, and backup energy infrastructure.
B2B energy procurement managers, engineers, and grid contractors prioritize strict compliance standards and long-term durability. Across modern applications, three core requirements guide procurement decisions: safety certifications, performance warranties, and multi-inverter BMS compatibility.
AC-coupled batteries integrated into global systems must carry UL 1973, UL 9540A, and CE EN62619 safety marks. Our systems undergo extensive thermal runaway validation tests to meet stringent regional codes.
Our systems feature multi-protocol configuration engines supporting CAN, RS485, and Modbus TCP. This enables direct integration with leading global hybrid inverters like SMA, Victron, Deye, and Growatt.
Using premium LFP chemistry, our systems maintain over 80% state-of-health (SOH) after 6,000 charge cycles at 0.5C charge/discharge rates, guaranteeing long operational lifespans.
For factories experiencing peak utility rates during daytime manufacturing shifts, AC-coupled battery arrays deploy stored energy when rates peak, reducing demand charges.
Combine old PV systems with new wind turbines and battery backup. AC-coupling serves as the central grid-forming unit to supply robust off-grid power.
For facilities where clean power is critical, AC coupled battery storage functions alongside generator sets to bridge runtime gaps and prevent data corruption.
Engineered to integrate seamlessly with existing solar arrays, wind turbines, and backup microgrids.
