PV grid-connected inverter regard as photovoltaic cells and power grid interface device to make the photovoltaic battery power into AC power and transmit to the power grid, which plays a key role in a PV grid power generation system. Modern inverter technology provides a strong technical and theoretical support in the development of PV grid power. Grid-connected inverter is moving toward high efficiency, high power density, high reliability, intelligent direction
At present, Zhejiang Ever-Shining New-Tech-Energy Co; Ltd has successfully developed two series of high power and small power with 28 types of PV grid-connected inverters, which including high-power system: 500.0KW, 250.0KW, 100.0KW, 50.0KW, 30.0KW, 17.0KW, 12.0KW and 10.0KW totally 8 types mainly apply into domestic large-scale solar power station. Small power including 1.5KW, 2.0KW, 2.5KW, 3.0KW, 5.0KW, 5.4KW totally 6 types mainly apply into the household type roof solar PV power generation systems.
