Project Case | 6 × 50kW / 100kWh Custom Energy Storage Cabinets for Indonesia Project Overview

This project involves the delivery of six (6) customized 50kW / 100kWh energy storage cabinets to Indonesia, designed for a grid-connected (on-grid) application.
The systems are currently in final assembly and testing and will be shipped soon.

Unlike standard off-the-shelf products, this project follows a one-project-one-solution design philosophy. The system configuration, cabinet structure, protection level, and internal components were all customized according to the local grid conditions, climate, and application requirements in Indonesia.

This project once again demonstrates our strong capabilities in custom energy storage system (ESS) design, manufacturing, and delivery.

Why Grid-Connected Energy Storage?

This project adopts a grid-connected (on-grid) energy storage system, which offers several key advantages for users in Indonesia:

Reduce Electricity Costs

By storing energy during off-peak hours and discharging during peak periods, the system helps reduce electricity bills through peak shaving and load shifting.

Improve Power Stability

The ESS responds quickly to grid fluctuations, improving power quality and ensuring stable operation for critical loads.

Support Renewable Energy Integration

Grid-connected storage works seamlessly with solar or other renewables, increasing self-consumption and reducing energy waste.

 Flexible Operation Modes

The system can be configured for different control strategies depending on grid conditions and user requirements.

Cabinet Design: Built for Harsh Environments

Indonesia’s climate is characterized by high humidity, heat, and frequent rainfall. To ensure long-term reliability, special attention was given to cabinet design.

Waterproof & Dustproof Structure

The cabinets in this project are designed with excellent waterproof and dustproof performance, suitable for outdoor installation.

More importantly, we do not limit customers to one fixed cabinet standard.

We provide customized cabinet protection levels, including but not limited to:

• IP21 – Suitable for indoor or protected environments
• IP54 – Basic outdoor protection
• IP65 – Dust-tight and strong water jet protection
• IP66 – Enhanced protection for extreme outdoor conditions

The protection level is fully customized based on project location, climate, and installation environment.

Capacity Customization: One Project, One Solution

There is no “standard size” for energy storage.

For this project:

• Each cabinet is 50kW / 100kWh
• Six cabinets are deployed as a system solution
• Designed to meet the customer’s specific power and energy requirements

Our approach is always:

One project → One dedicated solution

We support:

• Power customization from kW to multi-MW scale
• Capacity customization from kWh to MWh level
• System architecture customization (C&I ESS, BESS, microgrids, hybrid systems)
• Cabinet layout and internal structure customization

Whether it is a small commercial installation or a utility-scale, multi-MW energy storage project, every system is engineered based on actual load demand, grid conditions, and site environment — not predefined, off-the-shelf products.

Engineering Expertise You Can Trust

Behind every customized system is a strong engineering team.

• 12+ years of experience in the energy storage industry
•  Extensive experience in C&I ESS, microgrids, and grid-connected systems
• Long-term cooperation with China Top 500 enterprises
• Strong capabilities in system design, calculation, and optimization

Our engineers participate in the project from:

• Requirement analysis
• System design
• Component selection
• Cabinet integration
• Testing and commissioning

This ensures that every delivered system is safe, reliable, and tailored to real-world conditions.

Proven Track Record: Multiple Global Projects

This Indonesia project is not an isolated case.

We have delivered multiple customized energy storage projects across different regions and applications, including:

• Commercial & industrial energy storage
• Microgrid systems
• Grid-connected and off-grid solutions
• Projects in Southeast Asia, Africa, and other emerging markets

Each project strengthens our understanding of local grids, environments, and customer needs.

Commitment to the Indonesian Market

To better serve local customers, we are actively preparing to establish an Indonesian branch.

This means:

• Faster response time
• Local technical support
• Improved communication
• Stronger long-term cooperation

We are not just shipping systems — we are building long-term partnerships in Indonesia.
