Solar PV has experienced unprecedented growth in the last decade, with the most significant additions being utility-scale solar PV. The role of grid inverters is very critical in feeding power from distributed sources into the grid.
The high-voltage grid-connected inverter has a high-voltage output capacity. The AC grid-connected voltage levels of 1100V DC high-voltage inverters are generally 480Vac, 500Vac, 540Vac, etc., and the AC grid-connected voltage level of 1500V DC high-voltage inverters is 800Vac.
Next, we will explain in detail the differences between these two grid connection methods. High-voltage grid connection usually refers to directly connecting a photovoltaic power station to a medium-high voltage power grid. Its voltage level is generally above 10 kilovolts. Common voltage levels include 10 kV, 35 kV, etc.
The voltage level of the low-voltage grid connection system accessing the power grid is usually 380V (three-phase) or 220V (single-phase), which is exactly the common voltage in our daily electricity consumption.
