Inverter Duty | Solar Transformer

An inverter duty transformer is also known as a Solar Transformer & Step-up Transformer. These transformers are generally used in grid-tied photovoltaic solar power applications for providing galvanic isolation, stepping up the voltage and transferring energy to the utility grid.

Most grid tied photovoltaic solar power plants have an inverter duty transformer in the voltage/power transfer loop. The photovoltaic modules are made of photovoltaic cells which take in the photons produced by the incident sun rays, thereby creating a flow of electrons.

The electricity generated is usually direct current (DC). This direct current is then fed into an invertor which transforms the DC into an alternating current (AC). However the voltage generated by this inverter is in few kilo volts (KV) which is not possible to transfer to the power grid for further distribution and usage. The power grid takes voltages from the range of 11kV, 22 kV, 33 kV mostly. This is where the inverter duty transformer plays a big part by increasing the voltage to the required level.

Servokon offers a broad portfolio of Three Phase Transformers for Photovoltaic power solutions. The transformer primary side has multiple windings (3, 4, 5 etc.) which allows to connect multiple inverters to the grid with minimum number of transformers. They are specially designed to fulfilll customer requirements and conform to various national and international standards.
