4 FAQs about Solar inverter master and slave control

Can a master-slave control system control parallel inverters connected to a PV system?

This study proposes a master-slave control system for controlling parallel inverters connected to a PV system. The master inverter is connected to Energy Storage Devices (ESDs) and is responsible for maintaining stable voltage on the load bus.

What is the difference between a master and a slave inverter?

The master inverter is connected to Energy Storage Devices (ESDs) and is responsible for maintaining stable voltage on the load bus. The PV units are connected via slave inverters and are managed using a dual-loop Proportional Integrator Derivative (PID) control approach, with the outer loop maximizing solar panel output.

What is a master-slave control system?

The proposed system is intended to decrease the initial cost of the system. A master-slave control system is employed to distribute power among parallel systems. The storage inverter serves as the master inverter and is responsible for maintaining the system output voltage within an acceptable range.

Do inverters see the full array in master/slave mode?

As a contrary, in Master/Slave operation both inverters should "see" the full array, that is you should connect the inverter's inputs in parallel. Many big inverters in the MW range are indeed an assembly of units of 100 to 200 kW, which internally operate in Master/Slave mode.
