Technical FAQs 4

What is a bidirectional inverter?

In a solar power system equipped with a bidirectional inverter, excess energy generated during the day can be stored in batteries and then converted back to AC power for use when solar power generation is low. The bidirectional inverter's ability to manage energy flow more dynamically makes it an excellent choice for modern smart grid applications.

Are bidirectional inverters a good choice for energy management?

However, they do have limitations, particularly when it comes to energy storage and flexibility in energy management. Bidirectional inverters, on the other hand, offer greater flexibility. As the name suggests, they can convert energy in both directions – from DC to AC and from AC back to DC.

What is a bidirectional grid connected converter (BGC)?

The Bidirectional Grid Connected converter (BGC) is a key interface connecting the power grid and DC microgrid systems, which can realize bi-directional energy flow. The most common control method for grid-connected inverters is voltage and current double closed-loop control based on a proportional-integral (PI) regulator.

How do you control a grid connected inverter?

The most common control method for grid-connected inverters is voltage and current double closed-loop control based on a proportional-integral (PI) regulator. This control method can control the stability of the bus voltage on the DC side and ensure bi-directional power flow .
