At Suleman Foods, a 400 kW solar system with 5 Huawei inverters was synchronized with multiple diesel generators: 200 kVA, 100 kVA, and 75 kVA. The system supports solar-DG operation, grid export when net metering is enabled, and zero-export operation when required.

PV-DG Synchronization
Primary Outcome
Solar Utilization Improvement
Industrial operations faced inefficient load management between solar and multiple DG sets, leading to excessive fuel consumption and unstable power distribution. The absence of proper export control also created challenges in managing surplus solar energy with and without net metering.
Design and deployment of a PV-DG Synchronization Controller for a 400 kW solar system integrated with multiple diesel generators, grid supply, and export-control operating modes.
Automatrix Engineering implemented an advanced PV-DG synchronization controller enabling dynamic load sharing between solar and generators. The system prioritizes solar energy, manages DG contribution, and ensures zero-export or controlled export based on grid conditions.
The system was integrated with 5 Huawei inverters and synchronized with 200 kVA, 100 kVA, and 75 kVA diesel generators. Customized control logic was deployed to maintain generator-safe hybrid operation and maximize solar utilization when grid power is available.
The project improved solar-DG coordination, reduced diesel dependency, and achieved stable power management with seamless transition modes. The system supports export under net metering and zero-export compliance when export is not allowed.
