2. Project Background
Industrial parks in Southeast Asia commonly face weak grids, voltage fluctuations, and frequent power outages. Combined with high-temperature, high-humidity, and salt spray environments, traditional power supply methods have high costs and poor stability.
This industrial customer customized a 1500VDC high-voltage microgrid system and required direct 400VAC industrial voltage output to realize coordinated operation of solar PV, diesel generators, and the utility grid.
The technical threshold of this high-voltage customized solution was very high. Many energy storage manufacturers declined the project due to the complexity of multi-energy coupling control and high-voltage to low-voltage adaptation. The customer finally selected GSL Energy for the customized project deployment.
Core Customer Requirements
High-voltage architecture: 1500VDC high-voltage DC system to reduce line losses in high-temperature environments
Direct power supply: Direct 400VAC output without external transformers
Multi-energy coordination: PV/GEN/GRID hybrid microgrid architecture
Harsh environment adaptation: High-temperature resistance, moisture-proof, salt spray corrosion protection
On-grid/off-grid switching: Automatic islanding operation during faults to ensure uninterrupted production
One-stop delivery: Full-process integrated customization service
3. Technical Breakthrough: 690VAC Power Conversion Technology
Mainstream 1000VDC low-voltage PCS solutions in the industry cannot support high-voltage systems. GSL Energy adopted a self-developed 690VAC high-voltage conversion solution to solve the technical challenge of converting 1500VDC high-voltage energy storage to direct 400VAC output, suitable for weak-grid conditions in Southeast Asia.
Core Technical Highlights
Native support for 1500VDC high-voltage battery clusters with containerized integrated layout and high energy density
690VAC to 400VAC secondary voltage stabilization with low voltage fluctuation for precision industrial loads
High-voltage circuits reduce current losses, slow equipment aging in high temperatures, and extend service life
Customized weak-grid EMS algorithm with automatic voltage stabilization, frequency regulation, and harmonic suppression
Enhanced heat dissipation, dehumidification, and anti-corrosion structure for tropical environments
Reserved multi-energy interfaces compatible with intelligent multi-power-source coordination
4. One-Stop Mass Production and Prefabricated Delivery
Based on the intelligent manufacturing factory of GSL Energy, this project achieved full factory prefabrication, integration, and commissioning, demonstrating both large-scale production capability and non-standard customization capability.
Integrated Manufacturing
Battery systems, high-voltage PCS, fire protection, temperature control, and wiring fully pre-installed in the factory
Customized anti-corrosion, dehumidification, and enhanced cooling structure for high-temperature salt spray environments
EMS logic, on-grid/off-grid switching, and multi-energy coordination fully simulated and tested before delivery
Simplified onsite delivery with only lifting and grid connection required, greatly reducing overseas construction time
Integrated Core Systems
6MWh energy storage battery system + 2MW customized high-voltage PCS
Solar PV access system and diesel generator linkage module
Self-developed EMS energy management system and on-grid/off-grid protection device
Cloud-based remote intelligent monitoring and operation platform
5. Technical Service Capability and Long-Term Cooperation
For the complex requirements of the customized high-voltage microgrid project, the GSL technical team coordinated with the local time zone, accurately matched customer technical requirements, and quickly optimized electrical topology and control logic to efficiently complete the customized solution.
The strong factory manufacturing capability and technical service capability received high recognition from the customer.
6. Project Summary
The Southeast Asia 2MW/4.6MWh microgrid project verified the mature technical capability of GSL Energy in 1500VDC high-voltage architecture, high-voltage and low-voltage conversion, harsh environment adaptation, and multi-energy coupling.
With its own manufacturing factory, the company can quickly complete non-standard customization, integrated mass production, and overseas delivery, providing rare high-voltage microgrid manufacturing capability in the industry.
In the future, GSL Energy will continue to optimize high-voltage energy storage and microgrid technology, providing highly reliable and integrated energy storage microgrid solutions for industrial customers in weak-grid and harsh-environment regions worldwide.
