Establish a stable local grid
A grid-forming source provides voltage and frequency references. Not every PCS supports grid-forming operation.

Microgrids & off-grid
A controllable local grid that balances variable generation, storage, backup generation and diverse loads.
01 / Microgrids & off-grid
Find your configuration
Start with your actual energy needs. These are design pathways; site conditions determine equipment, capacity and functions.
System configuration / 01
Weak-grid campus: connected & islanded
Coordinate with the grid in normal operation and isolate when designed to do so, managing buildings, PV, storage and generators.
Discuss this configurationSystem configurationPV + BESS + PCC transfer/protection + microgrid controller
Design consideration
Validate island transitions, resynchronisation and supply restoration as system functions.
02 / SYSTEM LOGIC
How the system works together
SYSTEM FLOW / CONCEPT
Understand where power comes from — and where it goes
Explain the solution by operating state, not just equipment. The key questions: how it charges by day, supplies at night, and protects loads during local or citywide outages.
01Solar generation
Serve loads first, charge surplus
02Inverter / PCS / protection
Defines safe transfer
03Site loads
Use power by operating strategy
Day charging
Conceptual flow, not an electrical single-line diagram. Wiring, protection and transfer performance require project design and testing.Day: solar serves loads first; surplus charges storage or exports where permitted.
01Solar & wind
Uses assessed local solar or wind resources.
02BESS
Buffers variation and stores energy for later.
03Grid-forming PCS
Establishes voltage and frequency in island mode.
04Genset
Supports low-resource or high-demand periods.
05Microgrid controller
Coordinates sources, priorities, transitions and recovery.
Functional overview · wiring, protection and equipment follow the project design.
Balance sources, storage & demand
The controller allocates generation and storage, curtailing lower-priority loads when needed to preserve energy.
Retain backup for low generation
Schedule generators against battery state and forecasts, supported by fuel, spares and local operational capability.
Worst-season resource data
Combine solar resource, prolonged low-generation periods and seasonal demand. Add wind only where resources and maintenance justify it.
Dynamic stability & black start
Verify load steps, generator loss, communication failures and start sequence after a full outage; battery capacity alone cannot answer these.
Maintainable site conditions
Account for heat, dust, altitude, transport, fuel and local spares. Remote monitoring needs offline operation and recovery strategies.

Remote communities: year-round off-grid Design around household and public-service loads, seasonal resources and acceptable energy-shortfall risk, with maintainable backup.

Diesel-powered sites: reduce fuel use Integrate solar and storage with existing gensets, improving schedules and loading while respecting frequency, voltage and reverse-power limits.

Questions worth asking
Does a microgrid need wind?
No. A microgrid combines local sources, loads and coordinated controls. Select PV, wind, generators and storage according to the site.
Can generators be removed?
Assess worst-season output, prolonged low solar and acceptable shortfall risk. Retaining smaller backup generation may be more practical than very large batteries.
