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 high-voltage grid connection mode is more suitable for large-scale ground photovoltaic power stations that require long-distance transmission, while the low-voltage grid connection is more suitable for small-scale, short-distance transmission distributed projects.
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.
The low-voltage grid connection system does not require complex power transmission equipment, and installation and maintenance are also more convenient. For residents and small industrial and commercial users, the low-voltage grid connection system is undoubtedly a more economical and practical choice.
The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.
