2026 태양광 변압기 동향: 스마트 그리드 및 AI 기반 에너지 시스템의 핵심 허브

Neglected photovoltaic core equipment

With the continuous explosive growth of global photovoltaic installed capacity in 2026, 업계의 초점은 모듈과 인버터에 있는 경우가 많습니다., but a key equipment is often overlooked – solar transformers.

In modern photovoltaic systems, transformers not only undertake the basic function of voltage conversion, but also gradually evolve into intelligent, digital, and monitored key node devices, playing a core role in improving grid stability, system efficiency, and energy dispatch capabilities.

What is a photovoltaic transformer?

Photovoltaic transformers are mainly used for:

• Step up the low-voltage AC power (usually 400V-800V) output by the inverter
• Realize long-distance power transmission (such as 10kV-220kV)
• Ensure grid connection safety and electrical isolation

The main types of photovoltaic transformers

1.Oil immersed transformer

• Suitable for large ground power stations
• Excellent heat dissipation performance
• strong carrying capacity

2.건식 변압기

• Commonly used in industrial and commercial rooftop photovoltaics
• High safety (oil-free)
• Low maintenance cost

3.Box type transformer (pre installed)

• integrated design
• 쉬운 설치
