6 FAQs about [Anti-reverse charging function of photovoltaic inverter]

Why do photovoltaic power generation systems need anti-reverse flow equipment?

If there are many such power generating sources to transmit electricity to the power grid, the power quality of the power grid will be seriously degraded. Therefore, this type of photovoltaic power generation system must be equipped with anti-reverse flow equipment to prevent the occurrence of reverse power. How does backflow prevention work?

Is a photovoltaic grid connected system an anti-reverse current generation system?

The power grid company requires the photovoltaic grid-connected system to be built later to be an anti-reverse current generation system. What is anti-backflow? What is "countercurrent"? In the power system, the power is generally sent from the grid to the load, which is called forward current.

What is a power electronic based inverter?

In both standalone or grid-connected PV systems, power electronic based inverter is the main component that converts the DC power to AC power, delivering in this way the power to the AC loads or electrical grid.

What is reverse power relay (RPR) for solar?

Reverse power relay (RPR) for solar is used to eliminate any power reverse back to gird from an on-grid (grid-tie) PV power plant to the grid or to the generator by tripping either on-grid solar inverter or breaker or any contactor depending upon the type of power distribution and a control circuit.

What is a power inverter & a converter?

The power electronic devices such as converters, inverters contain various controlling and switching elements. The continuous operation of switching elements in the inverter and converter generates harmonic currents during non-linear loads. The injection of current distortions will cause power quality issues in the interconnected power network.

What is a safety feature of a PV inverter?

Islanding is the process in which the PV system continues to supply power to the local load even though the power grid is cutoff . A safety feature is to detect islanding condition and disable PV inverters to get rid of the hazardous conditions. The function of inverter is commonly referred to as the anti-islanding.
