PV4 Connector Case Study: 120MW Solar Project in Indonesia
This PV4 connector case study explains how PVLinkTech supplied IP68 PV4 connectors and Y-branch cable assemblies for a 120MW floating and ground-mount solar project in Indonesia. The connector configuration was selected for a 1,500V DC system operating in a humid tropical environment.
Project Background
The project involved a 120MW solar PV installation in Indonesia, combining floating and ground-mount applications. The EPC contractor required a DC connection solution for outdoor cable routing across a site exposed to humidity, seasonal rainfall, ultraviolet radiation and changing temperatures.
For a utility-scale solar project, connector selection is not limited to choosing a product with a stated protection rating. The connector has to match the cable specification, system voltage, branch layout and installation method.
PVLinkTech reviewed the project requirements before supply and prepared a PV4 connector and Y-branch cable assembly configuration for the confirmed 1,500V DC solar system.
The Challenge
Indonesia’s humid, tropical climate placed particular emphasis on outdoor connection protection. The project team needed connectors that could be used in the confirmed cable configuration while supporting the project’s requirements for water resistance and long-term outdoor use.
- Outdoor exposure to humidity, rainfall, dust and UV radiation
- A 1,500V DC solar PV system design
- PV4 connector compatibility for the confirmed project configuration
- Y-branch cable assemblies for applicable solar cable routing
PV4 Connector Case Study: The Connector Solution
PVLinkTech supplied IP68 PV4 connectors and Y-branch cable assemblies for the project. The solution was selected around the confirmed application requirements rather than as a general-purpose connector package.
| Application | Utility-scale floating and ground-mount solar PV |
|---|---|
| Project capacity | 120MW |
| Location | Indonesia |
| Connector type | PV4 connector configuration |
| Protection rating | IP68 |
| System voltage | 1,500V DC |
| Cable assembly | Y-branch cable assemblies for applicable connections |
| Compliance | TÜV / IEC 62852 for the applicable product configuration |
Verification and Delivery
Before production and shipment, the connector and cable assembly configuration was checked against the confirmed project requirements. Depending on the final product model and order requirements, applicable verification can include visual inspection, assembly checks, cable retention checks, continuity testing, labeling confirmation and packing inspection.
Project Outcome
The project received a PV4 connector and Y-branch cable assembly solution selected for its confirmed 1,500V DC design and tropical outdoor installation environment.
Key takeaway: For utility-scale solar PV, a connector must be selected as part of the complete cable and installation configuration—not only by its appearance or stated IP rating.
