Future Local Assembly for Battery Energy Storage Systems
Building a stronger local BESS supply chain for Malaysia and Southeast Asia — moving beyond distribution and system integration towards local assembly, customisation and value-added support.
Malaysia needs a stronger local energy-storage supply chain
The rapid growth of solar, BESS, data centres, industrial electrification and grid modernisation is creating strong demand for reliable energy storage solutions. Yet many BESS projects still depend heavily on imported, fully assembled systems.
As Malaysia develops more renewable energy and storage projects, the market will require stronger local participation.
The cost of import dependence
Relying on imported, fully assembled systems creates challenges such as:
- Longer delivery timelines
- Foreign-exchange exposure
- Limited local customisation
- Higher logistics costs
- Limited local technical support
- Dependency on overseas production schedules
- Harder after-sales service and spare-parts planning
- Limited local value creation
From importing products to building local capability
Solunar's local-assembly strategy is to build capability step by step — starting with system integration, testing and localisation, then assembly support, and eventually selected local assembly of BESS-related solutions.
This lets us create local value while maintaining product reliability, safety standards and global technology partnerships.
What future local assembly may include
Local value, global technology — potential activities include:
- Battery cabinet assembly
- Containerised BESS integration
- PCS and EMS integration
- Wiring and control-panel assembly
- Thermal management system integration
- Fire safety system integration
- Factory acceptance testing
- System configuration and software setup
- Local branding and project customisation
- Spare-parts and after-sales support centre
- O&M and technical training centre
Our roadmap for local BESS capability
A practical, scalable four-stage roadmap:
- 01
Stage 1 — Distribution & integration
Integrate proven international BESS solutions for the Malaysian market, with design, engineering and O&M support.
- 02
Stage 2 — Local testing & configuration
Factory acceptance support, local configuration, pre-commissioning checks, battery-health verification and training.
- 03
Stage 3 — Local assembly & customisation
Cabinet and container assembly, control-panel and auxiliary integration, fire and thermal systems, project-specific packaging.
- 04
Stage 4 — Regional BESS platform
Serve Malaysia and Southeast Asia across C&I, utility-scale, solar + BESS, microgrids and regional O&M.
Why local capability matters for customers
Local assembly is about trust, speed and serviceability across the value chain:
- Faster project delivery
- Better local technical support
- Improved spare-parts availability
- More flexible system customisation
- Reduced logistics complexity
- Potential cost optimisation
- Higher local-content participation
- Stronger after-sales service
- Better responsiveness during execution
- Greater confidence for long-term O&M
Local assembly must never compromise safety or reliability. Our approach prioritises approved battery technology, reliable architecture, electrical protection, thermal management, fire detection and suppression, quality control, factory and site acceptance testing, and compliance with applicable standards — combining global technology quality with local execution strength. These are forward-looking opportunities; current engagement focuses on technology distribution, system integration and O&M support.
