In the contemporary landscape of global decarbonization, utility-scale developers, commercial enterprises, and e-mobility operators require energy infrastructure that is certified, scalable, and thermally stable. Ningbo Sahnova Solar Co., Ltd. stands at the forefront of this industrial transition, operating as a premium manufacturer and exporter specializing in custom battery systems, intelligent thermal management solutions, and microgrid integrations. From automotive starting solutions to advanced utility-scale Lithium Iron Phosphate (LiFePO4) storage, Sahnova delivers robust, high-performance battery systems tailored for mission-critical reliability.
Originally starting with basic battery assembly and integration services, Sahnova systematically accumulated technical expertise in lithium battery topology design, hardware-in-the-loop (HIL) testing, and microgrid EMS integrations. Guided by a vision to facilitate the global transition to clean energy, we have upgraded our systems to include Factory 4.0 automation, active thermal management solutions, and specialized enclosures. These technologies ensure that our equipment meets safety and performance standards in the European Union, Americas, and APAC markets.
Today, Sahnova operates as a global engineering partner, providing key components like Battery Thermal Management Systems (BTMS) and modular battery packs, as well as turnkey energy systems like the Elecnova PV Grid-Tied Inverter Renewable Microgrid Solution. Our engineering processes are optimized to minimize the Levelized Cost of Storage (LCOS) while ensuring operation under strict thermal and mechanical stress profiles.
Developing next-generation energy storage requires structured innovation in electrochemistry, battery management software, and thermal control. Our current product design focuses on these three technology areas.
Our energy storage innovations rely on high-capacity LiFePO4 cells. Known for structural stability and resistance to thermal runaway, they are the preferred choice for industrial energy storage. Our current R&D focuses on:
A battery pack is only as reliable as its Battery Management System (BMS). Sahnova's smart BMS balances cells actively rather than passively, transferring energy from high-charge to low-charge cells. This design helps prevent localized degradation and extends overall pack lifespan:
For high-capacity installations, temperature control is critical to safety and longevity. Sahnova's BTMS systems (available in 8kW, 10kW, and 15kW options) regulate system temperature within a +/-2°C window:

We design custom energy storage systems that address the technical demands and regulatory standards of key global sectors.
Modern factories and logistics hubs face challenges from unstable grids and rising peak-demand charges. Our Elecnova PV Grid-Tied Inverter Microgrid Solution integrates solar arrays with smart energy storage. This allows facilities to peak-shave, perform load-shifting, and secure uninterruptible backup power. By pairing these systems with our 10kW-15kW BTMS units, industrial users can operate high-capacity systems under sustained heavy loads without thermal throttling.
E-bikes, E-scooters, and electric three-wheelers require reliable vibration resistance, compact design, and high current discharge rates. Our high-rate 36V, 48V, 60V, and 72V LiFePO4 packs are engineered for these demands. They feature laser-welded cell connections and custom sheet-metal battery boxes that resist water and mechanical impacts, ensuring safety in demanding urban transport environments.
Telecom towers and municipal service facilities need reliable standby power. Our Municipal Works Power Bank (360Wh) and custom large-format Lifesafety Sealed Battery Enclosures provide backup power for critical signaling and communication systems. They offer reliable long-term performance as direct replacements for older lead-acid batteries, delivering five times the operational lifespan without regular maintenance.

Our production facility in Ningbo uses advanced automation and strict quality management to ensure consistent manufacturing quality and steady supply chain output.
Operating out of Ningbo, a global hub for shipping and industrial manufacturing, Sahnova utilizes a complete domestic supply chain for raw materials. This local access to high-purity lithium iron phosphate, advanced battery management system chips, and precision sheet metal fabrication allows us to offer competitive lead times and cost-efficiencies for international buyers.
Our manufacturing facility is equipped with automated cell grading and sorting systems, ensuring that only cells within a 2mV voltage deviation and 0.5mΩ internal resistance variance are assembled into the same pack. Our Flexible Battery Pack Assembly Manufacturing System allows us to adjust production lines quickly to accommodate different cell form factors (prismatic, cylindrical, pouch) and custom pack sizes. This manufacturing flexibility is paired with rigorous safety testing, including high-temperature aging chambers, vibration test tables, and simulated short-circuit stress tests.
We design and manufacture our products to comply with international regulatory and safety standards, helping to streamline deployment in your local market.
Entering international energy markets requires meeting strict safety, electromagnetic compatibility, and environmental standards. Sahnova maintains certified manufacturing systems and product lines to support smooth compliance and import clearance:
Beyond manufacturing, Sahnova provides localization support for EPC contractors and system integrators. We offer custom-engineered enclosures designed to meet local wind load, seismic, and electrical code requirements, helping to simplify permitting and installation processes.
Key considerations for procurement managers, EPC firms, and distributors when planning large-scale energy storage imports.
Procuring industrial energy storage requires balancing capital cost against long-term operating performance. Procurement managers should evaluate three key metrics when selecting a manufacturing partner:
While standard lead-acid batteries offer lower initial purchase costs, their high degradation rate and limited cycle life lead to replacement expenses within 3 to 5 years. Our high-cycle LiFePO4 battery packs help lower LCOS by providing up to 15 years of operational service. This reduces maintenance costs and overall lifetime cost of ownership.
Industrial battery packs must integrate with existing power conversion systems (PCS). Our systems support common communication protocols like Modbus TCP/RTU and CANbus, allowing them to interface directly with leading commercial inverters and energy management systems (EMS). This compatibility simplifies installation and commissioning on site.
High ambient temperatures can accelerate cell degradation. Using an active thermal management system like Sahnova's BTMS helps maintain optimal operating temperatures, preserving cycle life and protecting your investment in warm climates.
