Worried Your Solar Power System Might Not Be Approved by Decision 378/QĐ-EVN?

Decision 378/QĐ-EVN is now a crucial compliance requirement for solar power investors in Vietnam.
This article will help you understand the technical requirements of QĐ378/EVN and introduce Uboard – an intelligent platform for monitoring and controlling solar power systems that fully meets EVN standards, ensuring your system is approved, safe, and efficient in operation.

1. The concerns of solar investors in 2025

You may have already installed hundreds of kWp of rooftop solar panels, yet still feel uncertain: “Does my system comply with Decree 58/NĐ-CP and Decision 378/QĐ-EVN?”

This concern is shared by many – especially in 2025, as EVN strengthens its supervision and control requirements for solar power systems with a capacity of 100 kWp or higher.
Meeting the EVN 378 standard is no longer just a technical guideline – it has become a mandatory condition for grid connection and stable operation.

2. Technical requirements under Decision 378/QĐ-EVN

According to the latest regulations, every solar power project must:
✅ Monitor all inverter parameters, including voltage, current, power, and generation output.
✅ Deploy a centralized data-collection system that automatically transmits information to EVN’s dispatch center.
✅ Support the Modbus TCP / IEC 60870-5-104 communication protocols and generate reports in the standardized EVN data format.

These requirements help EVN effectively manage and control generation capacity while ensuring the safety of the national power grid.

⚠️ If your system fails to comply, your business may face:
• The risk of being denied grid connection approval.
• Delays in acceptance testing or operational interruptions.
• Higher corrective costs and lost opportunities for stable operation.
