Shanghai, June 2025 —
As global attention continues to focus on the scalability, efficiency, and resilience of renewable energy systems, BOCO Electronics showcased a comprehensive portfolio of advanced power conversion and energy management solutions at SNEC PV+ 2025. Through three system-level solution demonstrations and the launch of a new 130kW commercial and industrial (C&I) energy storage PCS, the company addressed critical bottlenecks in next-generation photovoltaic, energy storage, and microgrid applications.
Rather than presenting isolated components, BOCO Electronics emphasized architecture-level optimization, reflecting a growing industry shift from device-level efficiency gains toward holistic system performance improvements.
One of the central challenges in high-power applications—such as ultra-fast EV charging hubs and industrial parks—is the limitation of available grid capacity. Conventional AC-coupled solutions often require costly grid upgrades and suffer from cumulative conversion losses.
BOCO Electronics presented a DC-coupled PV–storage–load architecture that integrates DC-DC converters, energy storage PCS, rectifiers, and MPPT controllers into a unified DC microgrid. By reducing the number of AC–DC and DC–AC conversion stages, the system achieves up to 98% energy conversion efficiency across PV-to-storage, PV-to-load, and storage-to-load pathways.
The architecture supports both 750V and 1500V DC platforms, enabling flexible battery cluster configurations and compatibility with a wide range of PV and storage technologies. Modular parallel expansion allows system capacity to scale incrementally, reducing upfront investment and shortening deployment cycles.
This solution is designed for applications including ultra-fast charging stations, PV-integrated industrial parks, and renewable-powered hydrogen production, where energy efficiency, scalability, and controllability are critical economic drivers.
In large-scale PV and storage systems, energy losses frequently arise from PV string mismatch, battery chemistry constraints, and multi-stage conversion architectures. To address these issues, BOCO Electronics introduced a silicon carbide (SiC)-based bidirectional DC-DC solution focused on fine-grained energy management.
The system employs independent multi-channel MPPT tracking, significantly improving energy yield under partial shading and low-irradiance conditions. Its modular architecture supports 5 to 20 battery clusters, enabling the parallel use of lithium-ion, sodium-ion, and flow batteries within the same system.
With a wide DC bus range of 750V to 1500V and single-stage conversion efficiency reaching 99.2%, the solution minimizes thermal losses and simplifies system design. High power density and compact form factors improve cabinet utilization, directly enhancing return on investment per square meter.
This approach allows system designers to adapt a single platform across centralized utility-scale storage, distributed PV-storage systems, and hybrid microgrids, reducing engineering complexity and lifecycle costs.
Beyond stationary systems, BOCO Electronics also demonstrated its GaN-based bidirectional energy storage solution targeting portable, emergency, and mobile power applications. Built on third-generation gallium nitride semiconductors, the system integrates a bidirectional inverter and MPPT controller into a compact architecture.
The solution delivers up to 96.5% charge–discharge efficiency, with 200% instantaneous overload capability, ensuring reliable operation of power tools and mission-critical equipment. An IP65-rated enclosure allows stable performance in harsh environments such as dust, rain, and extreme temperatures.
Supporting configurable capacities from 0.5 kWh to 5 kWh, the system can be deployed as a backpack power unit, mobile emergency supply, or modular household storage device. Cumulative shipments have exceeded 1.2 million units, demonstrating both technical maturity and market validation.
A highlight of the exhibition was the launch of BOCO Electronics’ 130kW C&I PCS, designed to serve as a high-reliability core component in distributed energy storage systems.
The PCS employs full SiC power devices and advanced magnetic integration, achieving 98% full-load efficiency and 99% peak efficiency. Thermal stability is a key design focus, enabling continuous full-load operation at 50°C ambient temperature and stable performance across a range of –20°C to +60°C.
The All-in-One architecture supports 20 ms on/off-grid switching, black-start functionality, and compatibility with lithium-ion, sodium-ion, and flow batteries. Modular parallel operation allows system capacity to scale up to 1.3 MW, supporting complex scenarios such as virtual power plants, desert charging infrastructure, and islanded microgrids.
At SNEC 2025, BOCO Electronics’ Gemini 125 bidirectional DC-DC converter received the “Top Ten Highlights Award”, an industry recognition shared with leading global energy equipment manufacturers.
The Gemini 125 features a full SiC topology, conversion efficiency exceeding 99.2%, and an ultra-wide voltage range of 600–1500V on both sides, enabling seamless integration of PV arrays and diverse battery technologies. Built-in MPPT functionality further simplifies system architecture.
The product has already been deployed in benchmark projects across Jiangsu, Shanxi, Shandong, and Xinjiang, delivering measurable improvements in system efficiency and operational flexibility.
From semiconductor selection and topology optimization to intelligent control algorithms and system-level integration, BOCO Electronics continues to invest in the fundamentals of power conversion engineering. By aligning component-level innovation with real-world application requirements, the company aims to enable safer, more efficient, and more resilient energy systems.
As renewable penetration increases and energy systems grow more complex, BOCO Electronics positions itself not merely as a component supplier, but as a system solution partner supporting the global transition toward cleaner and more intelligent energy infrastructure.
