From June 3 to 5, SNEC PV+ 2026 was successfully held at the National Exhibition and Convention Center (Shanghai). Topology Electric Power appeared at Booth D660, Hall 8.1, showcasing its latest energy storage solutions and core technologies across three key sectors: utility-scale energy storage, residential energy storage, and small-scale energy storage applications.
As a company with deep expertise in bidirectional power conversion and power electronics technologies, Topology Electric Power continues to drive product innovation around system reliability, application adaptability, and intelligent energy management, while actively exploring the future development and practical implementation of energy storage technologies together with industry partners.
Medium and Large-Scale Energy Storage Solutions
Designed for Large-Scale Energy Storage and Microgrid Applications
At the exhibition, Topology Electric Power highlighted several flagship solutions, including the String PCS & Step-Up Transformer Integrated System, MW-Level Energy Storage Solution Cabinet, and Microgrid Grid-Connected/Off-Grid Solution Cabinet.
The String PCS & Step-Up Transformer Integrated System integrates key components such as PCS modules, step-up transformers, and switchgear into a single platform. Flexible configuration of PCS and transformer capacities enables customers to build optimized energy storage systems with simplified deployment. Cluster-level management further enhances system efficiency, while multiple protection mechanisms ensure safe and reliable operation.
The MW-Level Energy Storage Solution Cabinet incorporates eight 125kW PCS modules, while the Microgrid Grid-Connected/Off-Grid Solution Cabinet integrates PCS, STS, and MPPT modules to meet advanced energy management requirements in complex energy scenarios.
To address the demands of utility-scale storage and microgrid applications, Topology Electric Power continues to optimize its PCS platform in terms of efficiency, scalability, reliability, and serviceability:
• Compact 3D design compatible with standard container transportation, reducing logistics and deployment costs
• Maximum conversion efficiency up to 99.1%, with average full-load efficiency reaching 98.3%
• Supports multi-unit parallel operation on both AC and DC sides for easy MW-scale system expansion
• 100% three-phase unbalance compensation capability
• Full-load operation at ambient temperatures up to 50°C
• No-load power consumption as low as 50W (customer verified)
• Hot-swappable maintenance for improved operational efficiency
Today, the solution has been deployed across Europe, Africa, Southeast Asia, and other global markets in applications such as PV-Storage-Diesel systems, peak shaving, mobile energy storage and charging, and off-grid backup power.
Residential Energy Storage Solutions
Intelligent Energy Management for Residential and Light Commercial Applications
For residential and small commercial energy storage applications, Topology Electric Power showcased its Stacked Residential & Commercial ESS Solution and All-in-One PV-Storage-Charging Solution.
The Stacked Split-Type High-Voltage Battery supports flexible mixed parallel operation of 6kWh and 9kWh battery modules, enabling scalable capacities from 6kWh to 144kWh. Built with 314Ah large-format battery cells and an integrated energy optimizer, the system supports mixed use of new and existing battery modules, eliminating capacity mismatch issues and maximizing lifetime energy throughput.
The modular architecture enables a single battery platform to support both residential and light commercial applications, offering advantages in capacity scalability, simplified SKU management, and rapid on-site deployment.
For light commercial scenarios, the 50/60kW Hybrid Inverter features IP66 protection, seamless grid/off-grid switching within 10ms, and support for 2× PV oversizing with a wide DC voltage range, providing greater system flexibility and improved energy utilization.
The All-in-One PV-Storage-Charging Solution is also built on a 314Ah large-format battery platform and supports PV-Storage, PV-Storage-Charging, and PV-Storage-Diesel-Charging applications. With an integrated energy optimizer, the system enables mixed battery operation and optimized energy throughput throughout its lifecycle.
The solution supports seamless integration with EV chargers, heat pumps, diesel generators, and VPP platforms, enabling intelligent energy dispatch across the entire energy ecosystem while maximizing overall system efficiency.
For overseas markets with high labor costs, the system adopts a plug-and-play installation design, significantly reducing installation and maintenance expenses. Meanwhile, coordinated management of battery storage and EV loads helps maximize solar energy self-consumption.
Small-Scale Energy Storage Solutions
Powering Balcony ESS and Lightweight Energy Applications
In the small-scale energy storage sector,Topology Electric Power demonstrated its latest balcony energy storage solution, marking the first application of 314Ah large-format battery cells in balcony ESS scenarios.
Rather than supplying complete balcony ESS products, Topology Electric Power focuses on providing core technologies and system solutions based on PCS, BMS, EMS, and MPPT platforms. This flexible approach allows customers to develop tailored solutions for both retrofit and new installation markets.
The solution supports both existing and newly installed residential systems, while its 2500W off-grid AC output is capable of powering common household appliances and critical loads.
Additional features include Bluetooth and Wi-Fi connectivity, cloud platform integration, IP65 protection, and built-in battery heating functionality, ensuring reliable operation under diverse environmental conditions.
The company also showcased its highly integrated 1kWh energy storage platform featuring:
• All-in-one EMS, BMS, PCS, and MPPT architecture
• 500W inverter power per battery cell
• Compact and high-efficiency design
• Comprehensive protection mechanisms
• Wide 12–60VDC PV input range
