A look back at an installation from the Emerald project archives.

For this Touws River project, we installed two 10 kVA Eaton UPS units to provide a redundant power arrangement.

If the supplying UPS becomes unavailable, the Eaton transfer unit automatically transfers the load to the alternative UPS. This allows one UPS to be taken offline for servicing while the other continues supplying user loads and circuits.

We completed the UPS installation, distribution boards, associated cabling, testing and commissioning.

The equipment may reflect an earlier generation of UPS technology, but the objective remains relevant: continuity during equipment failure or planned servicing.

A 550 kVA generator was only the starting point.

The client had already procured the generator, but it still needed the infrastructure required to operate as a complete standby-power system for a public-sector disaster-recovery IT centre.

Emerald collected the generator and delivered the project from container construction through to installation and commissioning.

The completed system included a purpose-built acoustic container, ventilation and exhaust routing, Deep Sea DSE335 controls, a Socomec ATyS-R 800 A automatic transfer switch, a Hager distribution-board retrofit, and the required electrical integration and protection.

The project was completed within one month, including the collection of the generator from the client.

Before handover, the generator, ATS and control sequence were tested under simulated utility-failure conditions to confirm that the complete system would start and perform the automatic changeover as intended.

Swipe through Project Spotlight Episode 04 to see how the generator became a complete standby-power solution.

The existing solar system was no longer giving the client the backup capacity they needed—so the solution required more than a simple equipment replacement.

For this project, Emerald retained and rewired the existing solar-panel array while redesigning and replacing the remaining system infrastructure.

The upgraded solution included:

⚡ 10 kW of inverter capacity
🔋 15 kWh of battery storage
☀️ Existing PV array retained and rewired
🏠 Household loads placed on backup
🍳 Geyser and stove left as non-essential loads
✅ Distribution and protection equipment redesigned
✅ COC and City approval completed

This installation comes from the Emerald project archive and demonstrates the type of backup-power assessment, redesign and upgrade work our team can provide.

Reliable infrastructure isn’t built by choosing equipment first.

It begins with understanding the operational requirements, identifying the risks and designing the right system around the needs of the site.

That is why Emerald Infrastructure Solutions provides independent technology advice rather than being tied to one manufacturer.

We support clients through the complete project lifecycle—from site assessment and system design to procurement, installation, commissioning and long-term maintenance.

Our practical experience includes critical power, standby generation, renewable energy, electrical infrastructure and server-room environments.

With 40+ years of combined experience, more than 100 critical power projects and over 30 maintenance clients, our focus remains the same: reliable solutions, structured delivery and continued support.

Built around reliability. Driven by practical experience.

A correctly sized cable must do more than carry the current—it must also deliver an acceptable voltage at the load.

Longer cable runs and higher load currents can increase voltage drop, potentially affecting equipment performance and overall system reliability.

In Episode 09 of Emerald Insights, we look at the Emerald Voltage Drop Calculator.

The calculator uses key project inputs—including load current, system voltage, phase type, cable length, cable construction and conductor size—to estimate:

• Voltage drop in volts
• Voltage drop as a percentage
• Whether the result falls within the entered allowable limit

In the example shown, the estimated voltage drop is 12.00 V, or 3.00%, against a maximum entered limit of 5%.

This provides a useful planning check, but final cable selection should always be verified by a qualified electrical professional against the actual installation conditions and applicable requirements.

Swipe through the slides to see how the calculator works.

Choosing a cable based on current alone can leave important installation risks unchecked.

The Emerald Cable Size Calculator considers the load, system voltage, cable length, conductor type, allowable voltage drop and installation derating before producing a preliminary recommendation.

For the example shown in this carousel, a 50 A three-phase load over a 30 m route produces a recommendation of:

• 10 mm² copper cable
• 10 mm² earth conductor
• 3.15 V estimated voltage drop
• 0.79% estimated voltage drop

Swipe through to see how the inputs become a cable recommendation—and which technical checks still matter before final selection.

Final cable sizing must always be confirmed by a qualified electrical professional according to the actual installation conditions and applicable requirements.

How much energy could a solar system generate—and what could that mean for electricity savings?

Emerald Insights — Episode 07 introduces our Solar Yield Calculator, a practical planning tool designed to provide an initial view of solar feasibility.

By entering information such as PV system size, daily electricity consumption, peak sun hours, electricity tariff, battery capacity and system cost, the calculator can estimate:

☀️ Daily, monthly and annual solar generation
🔋 Battery storage and estimated backup time
⚡ Solar contribution to daily consumption
💰 Potential annual savings and simple payback
🏢 Approximate panel quantity and roof area
🌱 Estimated long-term generation and CO₂ reduction

These results provide a useful starting point for discussing a potential solar project. Final system design should still account for the site’s load profile, roof conditions, shading, electrical infrastructure and operational requirements.

View the carousel to see how the calculator works, or visit the Emerald Knowledge Centre to explore the tool.

What role should a UPS play — and when is a standby generator needed as well?

We’ve launched the first edition of the Emerald Insights newsletter, where we’ll be taking a deeper look at practical topics around critical power, infrastructure and business continuity.

In our first edition, we explore the different roles of UPS systems and standby generators.

A generator can provide power through a longer outage once it has started and taken over the required load. A UPS can provide immediate continuity to selected equipment while that process takes place — but whether an operation needs one, the other, or both depends on the requirement.

The discussion starts with a simple question:
What happens to the operation when this load loses power?

Read the first edition of Emerald Insights and let us know what technical topics you’d like to see us explore in future editions:
