How is a solar transformer different from a standard transformer?

It is designed for inverter output, including harmonics, daily load cycling and sometimes dual LV windings for central inverters.

Can solar transformers be supplied with inverter skids?

Transformers can be supplied for integration into inverter skids or as standalone units, matched to the inverter specification.

Do you supply solar transformers for export?

Yes. Solar transformers are supplied to international PV projects, with standards and documentation for the destination.

Solar Transformer Supplier and Exporter

We supply inverter-duty step-up transformers for solar PV plants, designed for the harmonics and load cycles of inverter output. Designs include double-LV-winding units for central inverters and compact units for string inverter skids.

Before you request a quote

Winding arrangement: Central inverters often need double-LV-winding transformers; confirm with the inverter design.
Harmonics: State the inverter make or harmonic spectrum so the design allows for it.
Duty cycle: Daily load cycling affects ageing, so share the expected generation profile.
