What is a centralized photovoltaic inverter?
An inverter, also known as a power regulator or power controller, is a device that converts direct current (DC) electricity into alternating current (AC) electricity. The process of converting DC to AC is called inversion, and the device that performs this process is known as an inverter or inverter equipment.
A centralized photovoltaic inverter is a system that first gathers multiple parallel strings of solar modules to a DC input, performs maximum power point tracking (MPPT), and then converts the power to AC. Typically, the individual capacity of these inverters is over 500 kW.
Centralized photovoltaic inverter systems have high integration and power density. The power capacity has gradually increased from the initial 500 kW to 630 kW, 1.25 MW, 2.5 MW, 3.125 MW, 3.3 MW, 4.4 MW, and so on.
Centralized photovoltaic inverters are mainly applied in large-scale, ground-mounted photovoltaic power stations with uniform sunlight, such as those in mountainous areas, deserts, or on water surfaces.
