Microgrids & Stand Alone Power Systems

Microgrids & Stand Alone Power Systems

Switchboards to protect and control stand alone power systems (SAPS) and microgrids control various electricity sources such as BESS, gensets, solar and the grid to provide consistent power.

Microgrids and Stand-Alone Power Systems (SAPS) are both decentralized energy solutions that provide reliable electricity supply, especially in areas where traditional grid infrastructure may be unreliable or unavailable. They offer a degree of energy independence and can be crucial for remote communities, critical infrastructure, and even as a means of improving energy resilience in urban areas.

Microgrids and Stand-Alone Power Systems (SAPS) are both decentralized energy solutions.


In summary, both microgrids and stand-alone power systems offer solutions for decentralized and resilient energy generation and distribution. Microgrids are typically connected to the main grid but can operate independently when needed, whereas stand-alone power systems are completely isolated from the grid. Both systems play essential roles in improving energy access, reliability, and sustainability, depending on the specific application and requirements.

Here’s an overview of both concepts:




A microgrid is a small-scale, localized energy system that can operate either connected to the main grid or autonomously as an islanded system. It integrates various distributed energy resources (DERs) such as solar panels, wind turbines, batteries, and backup generators.


Main characteristics:



Microgrids can operate autonomously during grid outages, providing a reliable power source for critical infrastructure like hospitals, military bases, and remote communities.

Renewable Energy Integration

Microgrids often incorporate renewable energy sources, promoting sustainability and reducing greenhouse gas emissions.

Energy management

Advanced control systems and software manage the flow of electricity within a microgrid, optimizing energy use and minimizing costs.

Grid support

Microgrids can provide grid support services, such as peak shaving and frequency regulation, when connected to the main grid.




Remote communities

Microgrids can bring electricity to remote areas where grid access is impractical or too costly.

Industrial facilities

Microgrids enhance energy reliability for critical industrial operations.

Military bases

They improve energy security and reduce dependence on external power sources.

Urban areas

Some cities implement microgrids for localized energy resilience and renewable energy integration


Stand-Alone Power Systems (SAPS)


Stand-alone power systems, also known as off-grid systems, are completely independent of the main electrical grid. They generate, store, and distribute electricity locally, often using renewable energy sources and batteries.


Main characteristics:



SAPS operate independently of the main grid, making them suitable for remote locations or areas with unreliable grid access.

Energy storage

Battery systems are typically a crucial component of SAPS, allowing for energy storage when renewable resources are unavailable.

Diesel generators

In some cases, SAPS may include diesel generators as backup power sources during extended periods of low renewable energy generation.

Energy management

Advanced energy management systems are used to optimize the use of available energy sources and ensure reliability.




Remote homes and cabins

SAPS are used in rural and off-grid residences.


They provide power for remote cell towers and communication infrastructure.


SAPS can support off-grid agricultural operations and irrigation.

Mining and explorations

Remote mining sites often rely on SAPS for power supply.

What Our Clients Say

This company is excellent. We go to them first for Grid Protection Units. They offer great value especially when you add their top notch customer service. As usual, we needed something STAT this week and the team didn't leave us hanging, even finishing it up and testing on a Saturday to meet our timetable. Graham Dennis shout out.
Mark Horsfall (Simmark)

CTC has always provided great service on the many occasions we have worked with them on our solar projects. They are reliable, responsive, and overall an excellent company.
Daphne from The Greenguys Group

Big fan of these guys - always answer the phone. They helped me out when Endeavour Energy required a neutral voltage displacement protection function on the solar installation
