300kW / 600kWh Energy Storage System | Reliable Power Solution for Indonesia

Project Overview

This project involves the delivery of six (6) customized 50kW / 100kWh energy storage cabinets to Indonesia for a commercial grid-connected (on-grid) application.

The system is designed to improve power stability, reduce electricity costs, and enhance operational efficiency under local grid conditions.

The cabinets are currently in final assembly and testing prior to shipment.

System Configuration

Each 50kW / 100kWh cabinet includes:

• Battery System – 5 × 20kWh lithium battery modules
• PCS (Power Conversion System) – Stable DC/AC conversion for grid interaction
• EMS Control System – Real-time monitoring & intelligent energy management
• High Voltage Box – Integrated protection & safe distribution
• Industrial Air Cooling System – Designed for tropical climates
• Fire Protection System – Built-in safety components
• Grid-Connected Design – Fully compliant with local utility requirements

Total System Capacity:
300kW / 600kWh

Why Grid-Connected ESS?

1. Reduce Electricity Costs
2. Peak shaving and load shifting lower overall power bills.
3. Improve Power Stability
4. Fast response to grid fluctuations protects critical loads.
5. Flexible Operation Modes
6. Configurable control strategies based on user requirements.
7. Renewable Integration Ready
8. Supports seamless integration with solar or other renewable sources.

Customization Highlights

This project follows a one-project-one-solution philosophy:

• Power & capacity customized to client demand
• Cabinet protection level tailored for tropical environment (IP21–IP66 available)
• Structure and internal layout optimized for site conditions
• Engineered based on real grid parameters — not off-the-shelf products

Engineering & Delivery Strength

• 12+ years of energy storage experience
• Expertise in C&I ESS and grid-connected systems
• Full in-house engineering: design → integration → testing → commissioning
• Proven deployment experience across Southeast Asia and emerging markets
