2026 Fotovoltaiske transformatortrender: Kjernenav for Smart Grid og AI-drevne energisystemer

Neglected photovoltaic core equipment

With the continuous explosive growth of global photovoltaic installed capacity in 2026, bransjens fokus er ofte på moduler og invertere, but a key equipment is often overlooked – solcelletransformatorer.

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.Olje nedsenket transformator

• Suitable for large ground power stations
• Utmerket varmeavledningsytelse
• strong carrying capacity

2.Transformator av tørr type

• Commonly used in industrial and commercial rooftop photovoltaics
• High safety (oil-free)
• Lav vedlikeholdskostnad

3.Box type transformer (pre installed)

• integrated design
• Enkel installasjon
