FAQs 6

What is a high voltage grid connected inverter?

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.

What is the difference between high voltage and low voltage grid connection?

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.

What is a high-voltage grid connection?

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.

What is the voltage level of a low-voltage grid connection system?

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.

Why should you choose a low-voltage grid connection system?

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.

How to choose a grid-connected PV inverter?

Efficiency: The selection of a grid-connected PV inverter is mainly based on its efficiency. The inverter must b e capable to attain a high ef ficiency over a wide range of loads. Due to the reduced, and high efficiency is achieved. and disconnect it fro m the grid for safety purposes, while supplying power to the local l oad. In
