Reduce Maximum Demand Charges. Expand Power Capacity. Strengthen Energy Resilience.
Solunar helps factories, commercial buildings, industrial facilities and large power users deploy advanced Battery Energy Storage Systems to reduce peak demand, support power expansion and improve energy cost control.
Electricity cost is no longer just about consumption
For many commercial and industrial users in Malaysia, the electricity bill is no longer driven by energy consumption alone. Maximum demand charges, limited incoming capacity and the cost of grid upgrades now shape the true cost of power.
As factories expand production, install more machinery, add EV chargers or increase cooling load, many sites hit the same wall: the available power supply is not enough, and upgrading it can be costly, slow and complex.
What C&I energy users are facing
Commercial and industrial sites across Malaysia share a common set of pressures:
- Higher maximum demand charges
- Limited incoming power capacity
- Expensive TNB power-upgrade requirements
- Operational risk from power interruptions
- Pressure to integrate solar, EV charging and electrification
- Difficulty justifying large upfront CAPEX for energy infrastructure
The Solunar solution
Solunar provides integrated Commercial & Industrial BESS solutions designed to help businesses manage power intelligently. We do not only supply batteries — we design a complete, bankable and operational BESS solution around your load, tariff and growth plans.
What a C&I BESS can do for you
A well-designed system turns energy from a fixed cost into a managed asset:
- Reduce maximum demand charges through peak shaving
- Store solar energy and discharge during high-demand periods
- Support power expansion without immediately upgrading the grid
- Improve power stability for critical operations
- Enable future EV charging, automation and electrification
- Improve energy resilience and business continuity
What we provide
Solunar supports C&I customers, solar EPCCs, project developers and financiers with:
- BESS system design and sizing
- Battery container or cabinet solution
- PCS and inverter integration
- EMS and control system integration
- Solar + BESS hybrid design
- Maximum demand peak shaving strategy
- Load profile analysis
- Project feasibility support
- Installation partner coordination
- Testing and commissioning support
- Remote monitoring and performance tracking
- Long-term O&M support
Designed for real business outcomes
Our BESS systems are not designed as standalone equipment. They are designed to solve business problems.
For industrial customers, that can mean reducing monthly maximum demand charges. For commercial buildings, managing peak load from air-conditioning, tenants and EV chargers. For factories, expanding production capacity without waiting for costly infrastructure upgrades. For solar owners, improving self-consumption and reducing exported or wasted solar energy.
C&I BESS use cases
The same battery can serve several roles depending on how the EMS is configured:
Maximum demand peak shaving
Discharge during peak periods to reduce the maximum demand the utility records.
Power expansion support
Add usable load when existing grid capacity is constrained — without waiting for upgrades.
Solar energy storage
Store excess solar generation and use it when the building needs it most.
Backup & resilience
Support critical loads and reduce disruption during power instability.
EV charging support
Enable higher-capacity EV charging without overstressing the site supply.
Frequently Asked Questions
Payback depends on your maximum-demand charges, tariff, load profile, system size and operating strategy. Solunar models this per site rather than promising a fixed figure.
Yes. BESS pairs with existing or new rooftop solar to store excess generation, lift self-consumption and shave demand — coordinated through the EMS.
Often not immediately. A BESS can supply additional peak power on demand, supporting expansion while any longer-term grid upgrade is planned.
