Off-Grid PV-Storage-Diesel Microgrid for Mining & Oilfields
Replace diesel generation with PV and storage; build a stable, reliable microgrid in off-grid and weak-grid areas to keep production power continuous.
Problems We Solve
PV output replaces part of diesel generation, cutting fuel procurement and transport costs.
Independent power systems that don't rely on the main grid — for weak-grid or grid-free areas.
Storage buffering coordinated with diesel gensets supports critical loads through solar fluctuations and load shocks.
EMS dispatches PV, storage and diesel in real time against load and irradiance, minimizing manual intervention.
System Composition
Four subsystems working together, with capacity customized to load profile and site conditions.
PV Array
Modules laid out per site and solar conditions — the system's priority clean power source.
Lithium Battery Storage
Smooths PV variability, supports load shocks, and discharges when irradiance is insufficient.
Diesel Generation
Backstop power engaged when storage is low, with automatic start/stop per SOC strategy.
EMS Energy Management
Unified dispatch of PV, storage and diesel — seamless grid/off-grid switching and optimal operation.
Service Scope
Delivery path from load profiling to remote O&M; containerized modules become stations quickly upon arrival.
Compile power load, operating hours and diesel consumption baseline
Optimize capacity mix against solar resources and load curve
PV-first, storage-buffered, diesel-backstop operating strategy
Factory-preintegrated equipment; container modules transported and installed quickly on site
Remote monitoring of operating data, remote strategy adjustment and fault alerts
Technical Points
Unified dispatch of three power sources with priority-based automatic output allocation.
Genset start/stop controlled by storage state of charge and load forecasting, reducing idle running.
Both grid-connected and off-grid modes; critical loads stay powered through switching.
Capacity extended container-module by container-module, phased with load growth.
Equipment selection and structural protection designed for high-temperature, dusty, high-humidity sites.
Operating data returned remotely; supports strategy adjustment, efficiency analysis and fault alerts.

FAQ
Mines, oilfields, drilling platforms and remote areas with weak, unstable or absent grid coverage.
It depends on load profile, operating hours and local solar conditions. We provide the method and assumptions; actual savings depend on operating data.
The system supports seamless grid/off-grid switching, with storage and diesel coordinating to keep critical loads powered.
Containerized modules — factory-preintegrated, quickly installed and commissioned on site.
Equipment selection and structural protection are designed for site temperature, humidity and dust conditions.
