Project Overview
Project Background
An LVK 522kWh energy storage cabinet paired with carport rooftop solar and DC fast-charging piles at a Jakarta logistics park, featuring a 250kW STS module for millisecond-level grid-to-island transitions.
Customer Needs
As the park fully adopted electric trucks, simultaneous high-power fast charging by multiple vehicles caused severe instantaneous power surges, leading to frequent transformer overloads and tripping. Furthermore, due to local grid transmission capacity limits, the utility company rejected the park's application for a capacity upgrade.
Application Focus
EV Charging Hub
Solution Design
Integrated ESS Design For Site Operations
LVK tailored a 522kWh integrated solar-storage-charging solution for the park. The system incorporates a 250kW STS (Static Transfer Switch) module, allowing the energy storage system to act as a grid buffer. This resolved the power bottleneck associated with high-power fast charging without requiring a transformer upgrade.

Results & Benefits
Project Outcomes
Green charging costs for the logistics fleet were reduced by 45%.
Achieved "virtual capacity expansion," eliminating the need for the massive investment and lengthy approval processes associated with applying to the utility for a grid capacity upgrade.
The estimated payback period (ROI) is 3.1 years.
