PV solar application flow (for PV inverter 100kVA-1250kVA)

Shinenergy PV solar transformer in the power grid not only has the function of pressure change, but also can isolate the power grid of the three harmonic equipment, protect the heating and insulation materials to reduce the life of the generator.

Due to the particularity of photovoltaic power generation, large-scale investment of photovoltaic grid connected system will inevitably lead to hidden trouble of reliability and stability of power grid, such as harmonic, flicker, DC bias, over-voltage and so on. Because of the isolated transformer, The leakage current resulting from potential fluctuations caused by the switching of an inverter power device and the small direct current produced by an inverter in control are effectively isolated and suppressed, then it will not adversely affect the power grid.
