Performance is Non-Negotiable

How We Make Sure Endurance Actually Works for Your Operation

You've probably seen sustainability tech that looks impressive in presentations but falls apart in real-world applications. Electric transport that can't handle your actual operation. "Eco-friendly" products that could never work.

We get it. Performance isn't negotiable when your business depends on keeping products cold.

Here's how we make sure Endurance actually works for your operation. This isn’t theory, it is how we make sure it handles your hardest days with your toughest routes.

We Start with Your Operation

We start with what you need it to do.

Our requirements form isn't a tick-box exercise. We need to understand your actual operation: delivery cycles, door opening patterns, the difference between your busiest depot and your quietest route. We map where you can plug in and where you can't.

Because there's no point designing a solution that works perfectly – but not for how you would actually use it.

We Are Ready for Your Hardest Days

Once we understand your operation, we run it through Sunswap Analytics™ our modelling system that uses ten years of weather data to predict how Endurance will perform across your routes.

We don't model your average Tuesday. We model your worst-case scenarios: the hottest summer day with maximum door openings, the coldest winter morning with a delayed departure, the route that always runs longer than planned.

The goal is to ensure Endurance works for your fleet and that the battery is the right-size the system so you're covered when everything goes slightly wrong, which, in transport is always a possibility.

You get performance predictions across conditions: energy use per route, charging requirements, solar contribution by season. Real numbers you can challenge and verify.

We Prove It on Your Actual Routes

Models are useful. Real-world trials are decisive.

We don't run controlled demonstrations on convenient routes. Endurance goes live on your operation, same routes, same drivers, same delivery pressures. We say, try your best to push Endurance to its limits.

We design trials around two scenarios: your typical day and your hardest day. Because it has to handle both.

The trial data then shows exactly how Endurance performs against your current setup.

We Show You the Real Numbers

When the trial's complete, you get transparent total cost of ownership analysis. Every assumption listed. Every calculation explained. Analysis that shows what happens if diesel prices rise 20% or electricity costs fall.

We can compare line by line Endurance versus your current diesel units. Capital cost, energy, maintenance, downtime, charging infrastructure. We don't hide the unfavorable comparisons behind averages.

You can challenge our numbers because you can see our working. Make your own adjustments. Test different scenarios.

We have seen time and time again, the business case stand up with Endurance delivering up to 81% operational savings and 43% savings across the total cost of ownership. The trial is how we prove it.

We Configure for Your Needs

If the numbers work and the trial proves performance, we can configure Endurance specifically for your operation. Battery size based on your longest routes. Charging approach that fits your depot operations. Compartment configurations and remote evaporators.

There is no one size fits all in the logistics industry.

We can also help with driver training on plug-in procedures. Integration with your existing fleet management systems, and more.

What This Actually Looks Like

DFDS proved Endurance on their longest, toughest route - Peterborough to Scotland and back. 22 hours of cooling on a single charge. Matt O'Dell at DFDS called it "the only feasible zero-emission option aligned to our fleet emission reduction targets."

Tesco ran Endurance across their complete range of delivery cycles. Cliff Smith, Fleet Engineering Manager: "We found the Sunswap system to be the standout for performance."

Bannister Transport committed their entire trailer fleet after seeing trial results. Tom Owens: "We know Sunswap can deliver the sustainable technology needed for our operations"

They were business decisions based on operational performance and proof.

Ready to Test the Fit?

Performance claims are easy to make. Performance in your operation is what matters.

If you're ready to see whether Endurance actually works for your routes, costs and operational requirements, the first step is understanding what we're designing for.
