MRC Energy Pty Ltd Since 2016: EXCELLENCE IN INDUSTRIAL, COMMERCIAL & RESIDENTIAL ELECTRICAL & SOLAR Who are MRC Energy? MRC Energy is registered with the Department of Labour.

MRC Energy is an associated company to the refurbishment industry renowned MRC Group. We focus on the specification, installation and maintenance of ‘turn-key’ building electrical solutions such as all types of Lighting, Power Supply, Distribution Boards, Switch Rooms, PV Solar Panels and General Electrical work. We have a strong focus on Certificate of Compliance Inspections and repairs. We work

closely with property owners, developers, facility managers and landlords delivering the highest quality electrical and power generation solutions for existing industrial, commercial and retail buildings. By working closely with clients to provide innovation from the earliest design stages through to final installation, we are able to provide the most cost-effective solutions, designed, manufactured and installed to the highest standards in the industry. This is then supported with our maintenance division providing continuous long-term maintenance of the supplied and installed electrical system.

New edition of SANS 10142 has some interesting clarification on a number of issues with regards solar. Heavy onus on the installer on compliance across a number of disciplines. EG Fire and Structural issues. MRC will be attending a training session at the ECA to remain at the cutting edge of compliance. Watch this space!

A faulty extension cable can start a fire.

Now imagine that same level of compromise inside the system running your business.

This isn’t hypothetical.

There’s been a recent warning in South Africa about non-compliant electrical products being sold online.

From the outside, they look exactly the same.

But internally?
Different materials.
Lower capacity.
Higher risk.

And that’s where it becomes a problem.

Because the same thing happens in larger power systems.

Not all installations are equal.
Not all components are what they claim to be.
And not all systems are built to handle real-world conditions.

You don’t see the issue on day one.

You see it later:
• When your system is under load
• When temperatures increase
• When something fails that shouldn’t have

And by then, it’s not a small problem anymore.

It’s downtime.
It’s disruption.
It’s cost.

This is where engineering matters.

At MRC Energy, we don’t just install systems.

We assess how power behaves under pressure.
How components interact.
And where hidden risks can sit inside a setup.

Because reliability isn’t about what works today. It’s about what still works when everything is pushed.

If you’re relying on your current system, it’s worth knowing what’s actually behind it. https://mrc-energy.co.za/contact-us/

Most solar systems are built for homes.
But when it comes to commercial systems, there isn’t room for guesswork.

There is a large difference between installing a system and building one for a business that can’t afford downtime.

In a commercial environment, power isn’t a convenience; it is an integral part of how the business runs.

When demand changes or systems switch, everything needs to respond properly.
Not sometimes. Every time.

This is where many systems fall short.

On paper, everything looks right, but under real conditions, things don’t always behave the way they should.

At this level, it’s not about adding solar, it’s about how the system is put together:

• Generation
• Storage
• Backup
• and how all of it works under load

Because a system isn’t judged by whether it turns on. It’s judged by how it performs when it matters.

That’s the difference between installing equipment and engineering a solution.

If your business relies on consistent power, it’s worth understanding whether your system is built for that level of demand.

The problem is not power failure, it is unstable power.

When a system switches between grid, generator, and battery without proper coordination, the transition is not always clean, and that is where problems begin.

Power dips.
Voltage spikes.

Brief interruptions that are often too quick to notice, but long enough to cause damage.

Over time, this leads to:

• Equipment stress and reduced lifespan
• Unexpected system trips
• Production interruptions
• Inconsistent performance across operations

Most of the time, businesses assume these issues are random.
They are not. They are usually a result of how the system is designed to handle change.

Backup power is only one part of the solution.

How your system transitions between sources is what determines stability. This is why switching needs to be engineered, not assumed.

If your system has ever:

1. Restarted unexpectedly
2. Tripped without a clear cause
3. Felt inconsistent during load changes

There is usually a reason, and it is worth understanding.

Most businesses don’t lose power because of outages; they lose power during the switch.

When systems are not properly integrated, the moment between grid, generator, and battery becomes the weakest point in the entire setup.

That is where downtime happens.
That is where equipment takes strain.
That is where operations stop.
And in most cases, it’s completely preventable.

This is where engineering matters.

For this project, we designed a system that prioritises continuity, not just backup:

• 400kW solar generation to reduce reliance on the grid
• 430kW Deye lithium battery storage to carry load when it matters
• 250kVA generator integration for extended backup
• 250kW Deye inverters managing system control
• 500 amp static transfer switch ensuring seamless changeover

Every component has a role, but more importantly, every component is coordinated.

No gaps between systems.
No delays in switching.
No uncertainty under load.

Most providers install equipment, but we engineer how power behaves when it matters most.

If your business relies on consistent power, the real question is not: “Do you have backup?”

It’s: “What happens in the moment your power changes?”

System configuration as specified includes 400kW solar with MPPT, 250kW per hour solar output, and a 500kW static transfer switch.
