Product Overview：

Photovoltaic isolation transformers use low-loss materials and have the characteristics of high output conversion efficiency. The product has a high load capacity, anti-interference, fireproof, moisture-proof, safe and reliable, power-saving and convenient maintenance, etc., and plays the role of isolated power supply in photoelectric conversion, and can work normally for a long time in outdoor high-temperature environment. Solar energy has attracted more and more attention due to its advantages of no pollution, no noise and wide distribution. At present, most of the photovoltaic grid-connected power generation systems contain isolation transformers, and there is a leakage current problem in photovoltaic power generation systems without isolation transformers.

Product features：

• Electrical isolation: The transformer is used to realize the electrical isolation between the photovoltaic power supply and the power grid.

• Prevent the DC component of the current from being injected into the grid: Since the DC power does not cause a change in the magnetic flux, the DC component of the PV inverter system will not flow into the grid through the isolation transformer.

• Anti-interference effect: the isolation transformer with a certain connection mode can eliminate the integer multiple harmonics of the 3rd and 3rd, and reduce the impact of higher harmonics and voltage fluctuations on the power grid.

• The role of stable voltage: when the system fails, it can effectively suppress the resonant overvoltage and steady-state overvoltage of the photovoltaic inverter system.
