TMR Transformers

Transforming Solar Energy

These transformers step up the alternating current (AC) output of solar inverters to the medium- or high-voltage level needed for the grid, enabling efficient energy transmission and distribution from PV plants.

Solar Transformers

TMR Transformers manufactures solar transformers purpose-built for solar photovoltaic (PV) power plants. In a PV plant the inverters produce alternating current from the panels; the solar transformer then steps this output up to the medium- or high-voltage level required to feed the grid, so energy can be evacuated efficiently with minimal loss.

Because PV output fluctuates with sunlight, solar transformers must tolerate frequent load cycling, harmonics from the inverters and wide temperature swings. Our solar transformers are engineered with robust insulation, low losses and low noise, in three-phase configurations at 50 Hz or 60 Hz, with primary voltages configured to match the array and inverter output and oil-immersed or air-cooled designs to suit the site. Custom cabinet and rating options are available for each project.

Whether for utility-scale solar farms, rooftop and commercial installations or hybrid renewable systems, TMR solar transformers maximise energy yield, support reliable grid integration and include protective features that safeguard the plant. As a manufacturer we tailor every unit to your PV design. Get a quote for a solar transformer for your installation.

FAQs

Frequently asked questions

What is a solar transformer?
A solar transformer is a transformer designed for solar photovoltaic power plants. It steps the alternating-current output of the PV inverters up to the medium- or high-voltage level required to feed the grid, allowing solar energy to be evacuated efficiently.
How is a solar transformer different from a standard transformer?
Solar transformers are built to handle the frequent load cycling, inverter harmonics and wide temperature swings typical of PV plants. They use robust insulation and low-loss designs to cope with fluctuating generation that a conventional transformer is not optimised for.
Does a solar transformer convert DC to AC?
No. Converting DC from the panels to AC is done by the inverter. The solar transformer then changes the voltage of that AC — typically stepping it up so the power can be exported to the grid.
What ratings does TMR offer for solar transformers?
TMR manufactures solar transformers in three-phase configurations at 50 Hz or 60 Hz, with primary voltages matched to your array and inverter output and oil-immersed or air-cooled designs. Each unit is custom-built for the installation.
