2026 太陽光発電トランスのトレンド: スマートグリッドとAI駆動エネルギーシステムの中核ハブ

Neglected photovoltaic core equipment

With the continuous explosive growth of global photovoltaic installed capacity in 2026, 業界ではモジュールとインバータに焦点が当てられることが多い, 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.油入変圧器

• Suitable for large ground power stations
• 優れた放熱性能
• strong carrying capacity

2.Dry type transformer

• Commonly used in industrial and commercial rooftop photovoltaics
• High safety (oil-free)
• 低いメンテナンスコスト

3.Box type transformer (pre installed)

• integrated design
• 簡単な取り付け
