Africa Village Microgrid Solution
Summary: The solar-diesel-storage hybrid microgrid provides stable, economical, and green electricity for villages without power, supporting basic education and healthcare services.
Solution Overview
Build solar-diesel-storage hybrid microgrids for villages in Sub-Saharan Africa and other areas with no electricity or extremely weak power supply, giving villagers access to stable, economical, and green electricity.
Key Points
- PV/diesel/storage hybrid, designed specifically for villages without electricity
- EMS remote monitoring, with automatic start/stop of diesel generators as backup
- Stable power supply for village schools, clinics, and households
- Lower cost and cleaner than pure diesel power supply
Applicable Scenarios and Challenges
Villages have long been without electricity or rely only on small diesel generators for intermittent power supply. Electricity for education, healthcare, lighting, and processing is difficult to guarantee, and the cost of electricity is high.
VGRID System Composition
- Power Conversion System (PCS): Supports parallel operation of PV and diesel generators, flexibly controls charging and discharging, and adapts to village load fluctuations.
- Static Transfer Switch (STS): Seamlessly switches when the main grid occasionally arrives or diesel generators start/stop, ensuring village public loads.
- Battery Energy Storage System (BESS): Stores solar energy during the day and supplies power at night, smoothing day-night and weather fluctuations.
- Energy Management System (EMS): Schedules according to village routines and load curves, extending battery life and reducing diesel consumption.
- Microgrid Power Switchgear (MPS): Integrated AC cabinet with dust-proof and insect-proof design, adapted to Africa's outdoor environment.
Core Value
- Ends the history of no electricity, supporting schools, clinics, and farmers' production
- More economical and cleaner than pure diesel generators
- Remote monitoring and O&M, reducing on-site manpower
- Can be expanded in phases according to village scale
Typical Applications
Suitable for centralized power supply for villages in Sub-Saharan Africa, border settlements, and agricultural cooperatives.

FAQ
Is O&M of a village microgrid difficult?
The system is remotely monitored by EMS, with faults predictable; core equipment is modular, and on-site replacement only requires a basic electrician.
How is billing handled for villages without a grid?
Public metering points or household prepaid meters can be configured, selling electricity under a village operator model, flexibly adapting to off-grid communities.
What if solar power is insufficient or there are consecutive rainy days?
EMS automatically dispatches diesel generators as backup, while energy storage smooths fluctuations, ensuring basic daily electricity is not interrupted.
What is the approximate investment for a single village, and how is the payback?
Modular configuration is based on the number of households and load. Compared with pure diesel, long-term fuel expenditure can be significantly reduced, and payback improves with diesel prices.
