Southeast Asia Electronics Factory
SiRay Energy successfully delivered a complete PV + BESS + Diesel smart microgrid system for a large electronics manufacturing facility in Southeast Asia. The project addresses critical power reliability challenges in a weak-grid region while significantly reducing diesel fuel consumption through intelligent energy dispatch.
Located in an industrial zone with unstable grid infrastructure, the electronics factory operates 24/7 production lines that demand uninterrupted power supply. Before the microgrid installation, the facility relied heavily on diesel generators, facing high fuel costs, noise pollution, and frequent maintenance downtime.
Rooftop photovoltaic array covering the entire factory roof
The client required a turnkey solution that integrates renewable energy, energy storage, and backup generation with seamless automatic switching and remote monitoring capabilities.
Large-scale rooftop solar array provides daytime clean energy, reducing grid import and diesel runtime.
20-foot containerized battery energy storage system housed in a climate-controlled enclosure for safety and longevity.
Two high-efficiency diesel generator sets serve as reliable backup power for extended cloudy periods and peak loads.

The microgrid interfaces with the factory's existing load switchgear through a dedicated AC coupling point. All power sources - PV, battery, and diesel - are synchronized and dispatched according to real-time load demand and economic optimization algorithms.
