Solar Photovoltaic Isolation Transformer

  • Solar Photovoltaic Isolation Transformer
  • Solar Photovoltaic Isolation Transformer

The Sike' s solar photovoltaic isolation transformer is applied to solve power grid problems in photovoltaic power generation, such as harmonic waves, flash changes, DC magnetic bias and overvoltage. The product is deployed between the electrical grid and grid connected inverters to segregate inverting and sending electric energy back to the grid.

Main applications of the transformer include photovoltaic power generation, wind power transmission, high power UPS devices, inverters, machine tools, medical devices and rectifiers.
