Synchronizing panels coordinate two or more power sources (multiple generators, generator plus utility, or generator plus solar) so that they share load smoothly. The panel matches voltage, frequency, and phase before paralleling, then balances active and reactive power between sources in real time.

Built around Schneider Electric's PowerLogic measurement and protection devices with a synchronising module and PLC-based load-sharing logic, the panel handles both manual and fully automatic paralleling sequences.

FAQ

Frequently asked questions

What does a synchronizing panel do?

It coordinates two or more power sources (multiple generators, generator plus utility, or generator plus solar) so they share load smoothly, matching voltage, frequency, and phase before paralleling, then balancing active and reactive power in real time.

Which sources can the panel parallel together?

It supports multi-source paralleling of generator, utility, and PV (solar), with active and reactive load sharing between sources.

What control and protection equipment is used?

It is built around Schneider Electric's PowerLogic measurement and protection devices, with a synchronising module, Modicon M580 PLC-based load-sharing logic, and a Magelis HMI touchscreen.

Does the panel support automatic paralleling?

Yes. It handles both manual and fully automatic paralleling sequences, with Modbus / Ethernet communication to the BMS.

Where are synchronizing panels typically deployed?

Typical applications include large hospitals and tertiary healthcare, data centres with multiple generators, industrial cogeneration plants, and mission-critical campus power systems.

How many generators can the panel parallel together?

The panel is configured to the project, sharing active and reactive load across multiple generators, and can also parallel generators with utility or PV (solar) sources.

Does the panel integrate with a building management system?

Yes. It provides Modbus / Ethernet communication to the BMS, with PowerLogic metering and an HMI touchscreen for monitoring and control.

Can paralleling run without operator intervention?

Yes. The PLC-based load-sharing logic handles fully automatic paralleling sequences, while manual operation remains available from the HMI when required.
