The low-voltage grid connection system is relatively simple. The main equipment includes low-voltage switchgear and distribution boxes, grid-connected inverters, electric energy metering equipment, etc.

What is the maximum output power of an inverter?

When the voltage of the grid is relatively low or around 340V, then the maximum output power of the inverter is 27.4*340*1.732=16kW. Under this voltage, no matter how large the module power is, the full-load output is impossible. 2. High grid voltage There are two conditions which might lead to a slightly high grid voltage.

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?

Its voltage level is generally above 10 kilovolts. Common voltage levels include 10 kV, 35 kV, etc. The high-voltage grid connection system can carry a larger power transmission capacity and is suitable for large-scale ground power stations, large industrial and commercial parks and other scenarios.
