Microgrid Solution for African Villages
Summary: The PV-diesel-storage hybrid microgrid provides stable, economical and green power for villages without electricity, supporting basic education and healthcare services.
Solution Overview
For villages in Sub-Saharan Africa and similar regions that have no electricity or extremely weak supply, we build PV-diesel-storage hybrid microgrids so that villagers can access stable, economical and green power.
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 diesel-only supply
Application Scenarios and Challenges
Villages have long been without electricity or rely only on small diesel generators for intermittent supply, making it difficult to guarantee power for education, healthcare, lighting and processing, while electricity costs remain high.
VGRID System Composition
- Power Conversion System (PCS): supports parallel operation of PV and diesel generators, with flexible charge/discharge control to adapt to village load fluctuations.
- Static Transfer Switch (STS): seamless switching when the main grid occasionally reaches the area or when diesel generators start and stop, ensuring power for 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): dispatches according to village daily routines and load curves, extending battery life and reducing diesel consumption.
- Microgrid AC Cabinet (MPS): an integrated AC cabinet with dust-proof and insect-proof design, suited to African field environments.
Core Value
- Ends the history of no electricity, supporting schools, clinics and farmers' production
- More economical and cleaner than diesel-only generators
- Remote monitoring and O&M, reducing on-site manpower
- Phased expansion according to village scale
Typical Applications
Suitable for centralized power supply in Sub-Saharan African villages, border settlements and agricultural cooperatives.

FAQ
Is O&M for a village microgrid difficult?
The system is remotely monitored by the EMS, with fault pre-warning; core equipment is modular, so on-site replacement only requires a basic electrician.
How is billing handled for a village without a grid?
A communal metering point or household prepaid meters can be configured, selling electricity under a village operator model, flexibly suited to off-grid communities.
What if solar generation is insufficient or there are consecutive rainy days?
The EMS automatically dispatches the diesel generator as backup, while energy storage smooths fluctuations, ensuring basic daily electricity supply is not interrupted.
What is the approximate investment for a single village, and how does payback work?
Configured modularly according to household count and load, it can significantly reduce costs compared with long-term fuel expenditure on diesel alone, with payback improving as diesel prices rise.
