Why Euro 6 gensets often break down at low load (construction site explanation)

16-03-2026 Battery Trailer Waarom Euro 6 aggregaten vaak problemen krijgen bij lage belasting Op veel bouwplaatsen staat een dieselaggregaat dat de hele dag draait. Maar vaak gebruikt de bouwplaats slechts een klein deel van het beschikbare vermogen. Een aggregaat van 100 kVA dat slechts 20–30 kVA levert, draait op ongeveer 20–30% belasting. Dat lijkt efficiënt. In werkelijkheid veroorzaakt dit juist technische problemen.Steeds meer aannemers en verhuurbedrijven merken dat moderne Euro 6 aggregaten vaker storingen vertonen wanneer ze langdurig op lage belasting draaien. Om te begrijpen waarom, moeten we kijken naar hoe een dieselmotor werkt. Dieselaggregaten zijn ontworpen voor hoge belasting Een dieselmotor werkt het efficiëntst wanneer hij onder een relatief hoge belasting draait.Onder deze omstandigheden: Wanneer de belasting te laag is, gebeurt het tegenovergestelde. De motor draait wel, maar produceert onvoldoende warmte en druk voor een optimale verbranding. Het probleem van onvolledige verbranding Bij lage belasting ontstaat onvolledige verbranding van dieselbrandstof. Dat leidt tot: Dit verschijnsel staat in de sector bekend als “wet stacking”. De brandstof verbrandt niet volledig en laat residu achter in het systeem. Wet stacking ontstaat wanneer onverbrande brandstof en roet zich ophopen in het uitlaatsysteem doordat de motor niet op voldoende temperatuur komt. Waarom aggregaten op bouwplaatsen vaak te

Grid congestion and construction projects: What does it mean for construction and infra in 2026?

09-03-2026 Battery Trailer What grid congestion means for construction and infrastructure projects in 2026? Grid congestion is increasingly affecting construction projects. Where grid connection used to be taken for granted, construction companies now have to actively consider temporary energy supply. Grid congestion is often presented as a temporary bottleneck in the power grid. In reality, it structurally changes the way construction and infrastructure projects are planned and executed. Where grid connection used to be taken for granted, energy is now becoming a limiting factor. The shift taking place Three developments are converging: Construction sites that used to run on diesel are switching to electric machines. At the same time, the demand for temporary connections is growing. The power grid is not designed for this.The result is predictable: waiting times, limited connections and rejections of grid reinforcement. Why this is not a temporary phase Grid expansion takes years. Projects run today. Even when the grid is expanded, demand will continue to grow. Electrification is not a trend but a structural shift. For construction and infrastructure companies, this means that energy supply is no longer a prerequisite, but a strategic part of project planning. The impact on project risk When energy is not available: Energy security thus becomes a risk factor within projects. The necessary mental shift Instead of asking: “Is there power?” The question should become: “How do we temporarily organise our energy infrastructure?” This requires: From

What does a Battery Trailer cost? And why is it so much cheaper than a diesel generator?

01-12-2025 Battery Trailer What does a Battery Trailer cost - and why is it so much cheaper than a diesel aggregate? More and more construction and civil engineering companies are switching to emission-free power supply. Not only because of stricter regulations, but also because it is financially and operationally smarter.One of the most frequently asked questions is, “What does a Battery Trailer cost - and what are the running costs compared to a diesel generator?” In this article, we set it out clearly. Purchase price: from compact to powerful The price of a Battery Trailer depends on the battery capacity and power. Several models are available, ranging from 24 kWh to 192 kWh. This allows you to always choose a model that suits your project: from small-scale construction sites to complete infrastructure projects. Running costs: much lower than diesel A traditional diesel generator runs continuously, even when hardly any power is required. This leads to unnecessary fuel consumption, noise and emissions. A Battery Trailer works differently: it only supplies energy when power is actually being used. Calculation example Battery Trailer (96 kWh)Full charging costs around €0.22 per kWh → €21 per chargeDiesel generatorAverage consumption: 4 litres of diesel per hour → 4 × €1.65 = ± €100 per day, excluding maintenance, filters, oil and fuel transport. The cost of a diesel generator is thus

Why Euro 6 generators break down so often. And why Battery Trailers do solve the problem

01-12-2025 Battery Trailer Why Euro 6 gensets break down so often - and why Battery Trailers do solve the problemMany construction companies and rental companies report the same problem: modern Euro 6 gensets (or Stage V generators) break down much more often than older models. Especially when they only run at 10-25% of their power all day.But why does this happen? And more importantly, what does it mean for on-site reliability? In this blog, we clearly explain what goes wrong technically and what the consequences are. Why modern gensets cope poorly with low load Euro 6 and Stage V gensets are designed to run cleaner, but that only works if the engine is regularly under high load. On construction sites, this is hardly ever the case: machines are idle, consumption fluctuates, there is peak and off-peak load, which is why many generators run at only 10-25% of capacity most of the time. That's exactly where things go wrong. The real problem: too low temperature and poor combustion When a diesel engine runs underload, combustion does not get hot enough. This causes a chain reaction: This lowers lubrication and accelerates wear. Why this leads to lower reliability? Construction companies notice it immediately: Euro 6 units that are not properly loaded often do not even make it to the end of

Lenferink Vastgoedonderhoud puts Battery Trailer in Enschede: emission-free building in practice

16-09-2025 Battery Trailer Last weeks, Lenferink Vastgoedonderhoud deployed the Battery Trailer on a special project in Enschede. For housing corporation Ons Huis, the preservation of 73 homes on Borneostraat, Celebesstraat and Wooldriksweg is being carried out. The aim: to make homes with cultural-historical value ready for the future in a sustainable way. And that includes an emission-free construction site. Entire building site on power from the Battery Trailer According to site manager Gerben van de Ploeg, this trial was more than successful. The entire fleet, the 10-tonne crane, power tools and the plasterers' pump ran on the Battery Trailer all day long. Reactions on the construction site were unanimously positive: Gerben summed it up nicely: "Does what it's supposed to do, and it just works well." Why this is important More and more construction companies and housing associations are switching to emission-free solutions. The Battery Trailer is helping to do just that: This project shows that zero-emission construction is not a pipe dream, but practice today.

5 Common misconceptions about the Battery Trailer

06-08-2025 Battery Trailer When making construction sites and event venues more sustainable, we regularly encounter scepticism and misunderstandings with the Battery Trailer (aka battery trailer). Not surprisingly, because change raises questions. In this article, we set the facts straight and show why this mobile energy solution is making a difference right now. Misconception 1: "Surely a battery like this will run out in no time?" Wrong.A common concern is that a battery trailer will not last long. In practice, most Battery Trailers easily last an entire working week on an average project.Moreover, thanks to the smart Remote App, you can always see in real time how much power is still available. This makes planning, recharging or swapping convenient and reliable. Misconception 2: "You always need an expensive grid connection." Also not true.The Battery Trailer is plug & play: you simply charge it via a standard EV charging station or a power connection. No fixed building connection or special grid management is needed. This makes it perfect for temporary construction sites, renovations or events. Misconception 3: "A diesel generator is cheaper." Not when you do the math.A traditional diesel generator seems cheap to buy, but has long since ceased to be so in use. A Battery Trailer saves up to 55,000 litres of diesel and 130 tonnes of CO₂ emissions per
