Explore our flagship power solutions designed for maximum efficiency, high-level protection, and all-weather applications.
The global demand for reliable, sustainable, and mobile power solutions has entered an era of rapid transition. Portable solar power bank chargers and micro-grids are no longer simple consumer gadgets designed for light camping trips. They have transformed into essential assets for industrial field operations, disaster relief grids, military deployment support, remote ecological monitoring, and urban micro-power systems.
As carbon neutrality mandates become central to international business regulations, companies across North America, Europe, and the Asia-Pacific region are restructuring their remote power systems. Modern smart portable solar generators combine photovoltaic energy capture, integrated high-efficiency storage, and digital telemetry interfaces. In sectors like telecommunications, off-grid telemetry, and mobile healthcare, securing a reliable custom supplier for these systems determines operational runtime and long-term cost resilience.
Underpinning this industrial leap is the integration of advanced Battery Management Systems (BMS) and highly reliable micro-inverters. Shenzhen Litongwei Electronic Technology Co., Ltd. is positioned at the intersection of this technology, developing safety protection systems that ensure solar charging circuits operate under peak efficiency while mitigating the risks of thermal runaway, over-voltage, and dynamic load failure.
A rigorous examination of safety electronics, BMS communication interfaces, and peak conversion engineering.
High-voltage portable solar power storage demands complex multi-series balancing. Our custom 10S, 13S, 20S, and 23S battery protection boards handle continuous discharge rates up to 200A. These boards optimize multi-cell configurations to prevent uneven degradation across the pack, extending lifespan by up to 45% compared to generic protection platforms.
Modern commercial portable power generators must interface seamlessly with digital monitoring infrastructure. By integrating Bluetooth, CAN communication protocols, and multi-point NTC temperature monitoring, operators can review real-time battery diagnostics via serial interfaces or mobile applications, making preemptive thermal management simple.
Our solutions feature up to 96.5% peak inverter conversion efficiency. IP67 all-weather protection guarantees performance in high-humidity or dust-heavy zones like agricultural stations or oceanfront micro-grids. Bidirectional inverter topologies enable both rapid solar charging and smooth, stable AC output within a single space-saving housing.
Established in 2005, Shenzhen Litongwei Electronic Technology Co., Ltd. is a national high-tech enterprise focused on the research, development, and high-volume manufacturing of lithium-ion safety control systems and power management boards. Over the last two decades, our engineering teams have focused on delivering intellectual property protection (patent collaboration to mitigate infringement risks), standard industry shared boards, full-process MES traceability, and cloud-based remote maintenance platforms.
Our lithium-ion safety control products are integrated into 3C digital systems, electric two-wheelers, electric golf carts, Automated Guided Vehicles (AGVs), drones, and portable outdoor solar power systems. Partnering with Litongwei means gaining access to automated production scales that deliver stable pricing, reliable manufacturing schedules, and zero-defect QA targets.
A history of persistent technological evolution, quality certification, and engineering innovation.
In 2005, the company commenced advanced R&D and manufacturing of digital Battery Management Systems. By 2006, it expanded into power battery management system development. ISO9001 and ISO14001 certifications were secured in 2007 and 2009 respectively, solidifying our baseline quality management frameworks.
During this stage, we secured 8 utility model and design patents while expanding our mobile power bank and custom charger manufacturing divisions. In 2012, we established the Litongwei Technology Research Institute. We received the Del New Energy Quality Excellence Award in 2014 and earned the Gold Partner title from Gaogong Lithium Battery in 2015.
We upgraded our quality systems to meet IATF16949 automotive-grade compliance in 2018. The company implemented a fully integrated MES system to achieve end-to-end traceability from raw components to finished products. Recognized as a market leader in protection board technology for two-wheeled vehicles in 2020.
Deepening our technical expertise under the Smart Manufacturing+ strategy, Litongwei has embraced IoT, industrial automation, and high-efficiency smart grid solutions. We continue to engineer premium power controls, micro-inverters, and high-voltage BMS systems for global portable solar charger applications.
LITONGWEI has always adhered to the philosophy of "Technology as King, Efficient Service" in all aspects of design, production, and supply operations. Our ultimate corporate vision is to serve as a reliable global provider of intelligent green energy management solutions. We design each product with environmental sustainability, high recovery efficiency, and carbon footprint reduction in mind.
We work closely with global industrial partners, system integrators, and distributors to ensure that the transition to green energy is safe, cost-efficient, and structurally sound. Our partnerships with household names and industry leaders highlight our commitment to zero-defect standards.
Adapting advanced power architectures to specific regional demands and technical developments.
From micro-solar grids for residential balcony systems in Central Europe to high-capacity rugged backup power systems for remote telecommunications stations in North America, Litongwei products adapt to local climate profiles. Our integrated heating elements in Bluetooth BMS units ensure battery charging can continue safely in sub-zero environments without causing lithium plating damage.
Our long-term R&D roadmap focuses on adapting current BMS configurations to manage hybrid solid-state battery systems. These next-generation systems deliver double the energy density of conventional cells while keeping charge control safe and operating stability high under variable solar irradiance profiles.
Integrating Maximum Power Point Tracking (MPPT) logic directly with BMS overcurrent systems allows solar generators to capture peak power even in partial shade. Bi-directional charging designs simplify internal component needs, reducing weight while retaining overall systems efficiency.
Custom engineering integrations built to lower structural overhead, maintain traceability, and minimize downtime.
Continuous backup power systems featuring custom 23S 60A/100A CAN bus BMS blocks. These systems maintain off-grid telecom towers using automated cellular solar arrays, reducing field dispatch costs.
High-discharge automated battery packs utilizing custom 13S/20S BMS systems. These setups allow autonomous vehicles to rapid-charge safely during operating intervals on the warehouse floor.
Integrating our IP67 96.5% high-efficiency micro-inverters with domestic solar systems. This enables urban residents to generate clean grid-tied AC electricity directly from window or balcony PV arrays.
Reliable, portable solar generators featuring 500W-1kWh single-cell capacities and bidirectional inverters. These units supply stable power to medical and diagnostic equipment in post-disaster zones.
