Whether you're running a fleet of service vans, utility vehicles, or mobile workshops, having reliable onboard power is critical. Pure sine wave inverters are the gold standard for converting DC battery power into clean, stable AC power—making them ideal for sensitive equipment and heavy-duty tools alike. In this guide, we’ll cover everything from what makes pure sine wave inverters superior, to why your fleet needs them, how to choose the right size, and what mistakes to avoid during installation.
What is a Pure Sine Wave Inverter – and Why Does It Matter for Your Fleet?
When it comes to powering tools, electronics, or essential systems in your vehicle, not all inverters are created equal. A pure sine wave inverter delivers a clean, stable current that's equivalent to what you'd get from the mains. Unlike modified sine wave inverters, which can produce a choppy or distorted waveform, pure sine wave inverters ensure compatibility with sensitive equipment like:
- Laptops and monitors
- Power tools with variable speed controls
- Utilities
- Audio-visual equipment
- Medical devices
At Daltec, our inverters are designed multi vehicle use ranging from fleet of vans to campervans to motorhomes. They offer consistent output and reliability in demanding environments. Whether you're on location, on call, or on the move – choose performance you can trust.
Top 5 Reasons You Need an Inverter in Your Fleet Vehicle
Modern fleet vehicles are more than just a means of transport—they’re mobile workstations. Here are five key reasons why your van or truck should be fitted with an inverter:
- Power Tools On-Site – Run drills, saws, or compressors without relying on site power.
- Charge Laptops & Devices – Perfect for engineers, surveyors, and mobile offices.
- Stay Compliant – Essential for certain equipment in emergency or regulated services.
- Improve Productivity – Reduce downtime by powering kit anywhere, anytime.
- Customer Service – Deliver faster results without waiting for external power sources
Daltec offers a range of pure sine wave inverters ideal for trades, fleet operators, and service-based businesses.
Inverter Sizing Made Easy – What Wattage Do You Actually Need?
Choosing the right inverter can feel overwhelming, especially with multiple wattages on offer. Here’s a quick breakdown:
- 300W–500W: Ideal for small devices like laptops, phone chargers, or low-power LED lighting.
- 1000W–1200W: Suitable for powering TVs, small tools, or printers.
- 2000W–3000W: Needed for larger tools, kettles, heaters, or multiple devices running simultaneously.
Top tip: Always add up the total wattage of your devices, then choose an inverter with at least 20% headroom. And don’t forget to consider peak power demand – some devices like drills or fridges spike when they start.
Daltec’s team can help you match the right inverter to your vehicle and equipment.
Avoid These 4 Common Inverter Mistakes
Installing or using an inverter incorrectly can cause damage or lead to inefficient performance. Here are some of the most common mistakes we see—and how to avoid them:
- Overloading the Inverter
Exceeding the wattage limit can trip your inverter or even damage connected devices. However, Daltec Pure Sine Wave Power Inverters automatically shutdown if overloaded to avoid this problem. - Poor Ventilation
Inverters generate heat. If installed in a tight, unventilated space, they can overheat and shut down. - Wrong Cable Sizes
Undersized wiring can create voltage drops or overheating. Always use cable suitable for the inverter’s draw. - No Surge Protection or Fuse
Power surges can damage both the inverter and your equipment. Always install appropriate fuses or breakers.
Daltec’s inverters are designed for durability—but they perform best when installed and maintained correctly.
