Carval provides your mobile workshop with the necessary power supplies
To work optimally, you always want to have the necessary power supplies in your mobile workshop. This way, you can always efficiently charge your batteries, power tools or machines on the road or in your workshop. This way, you are always operational, even if no mains power is provided or your vehicle is not running.
At Carval, we believe in customization and start with one simple but crucial question, "What are the specifications of your equipment and operations?". In addition, the number of miles driven daily, weekly or monthly plays a very important role in the electrical configuration.
Based on this, we develop a customized power supply solution with high-tech components. These always comply with the latest vehicle technology and the highest standards for electronics. Carval has everything in stock and provides both turnkey systems and separate components.
(Accessory) Batteries
Batteries
Different batteries can be offered depending on your requested specifications. For Lithium batteries, we also work with a high-tech BMS (Battery Management System) that optimally regulates the cell balance. Contact us for more information about batteries.
Accessory batteries
Carval provides a variety of chargers for your accessory batteries.
- DC-DC chargers conduct power from your vehicle battery to your accessory battery, 12V to 12V or 24V to 24V.
- AC-DC chargers guarantee efficient and continuous power transfer from 230V to 12V or 24V, keeping your batteries optimally charged at all times.

Inverters
An inverter, also known as an inverter, is essential to convert the low DC voltage (12V & 24V) from a battery into usable 230V AC voltage. Carval provides the inverters you need, so you always have access to the power you need, wherever you are. Our inverters deliver a pure sine wave output, so everything works optimally and without interference, as if you were at home.
Inverters in various capacities
According to the need, the power of the inverter is adjusted. The inverters in our product range are available in various power ratings, ranging from 400 watts to 3500 watts. In addition, we offer inverters with various voltage options, ranging from 12V and 24V to 48V. Depending on your needs, we can customize packages to meet your specific energy needs.
Both 230 output and 380V output
What makes our inverters even more powerful is their ability to provide not only the standard 230V output, but also a 380V output. By connecting 3 230V inverters together, we create a powerful 380V supply. This functionality makes our system particularly suitable for a variety of applications.

Isolation Monitoring
Optimize personal safety at isolated voltage sources with Carval insulation monitoring. Although more isolated voltage sources such as DC-AC inverters and dedicated generators are often considered safe, there is a risk of electrocution due to undetected insulation faults. Even small inverters can be potentially lethal.
The Carval insulation monitoring module disconnects consumers at the slightest insulation fault (<100kOhm), eliminating any risk of electrocution. Avoid unnecessary risks and choose optimum safety with our Carval insulation monitoring.
CAN bus module
With our advanced CAN (Controller Area Network) bus module, a product of our own development, we communicate directly with your vehicle. This direct connection allows us to read and utilize essential information, resulting in an optimally tuned equipment that meets the highest standards.
This integrated approach not only ensures the performance of the commercial vehicle, but also optimizes the durability and safety of the electrical components. Thanks to the reliable vehicle communication of our CAN-bus module, we can respond to customer-specific needs with customized solutions.

Power generator
Carval provides the appropriate power group, also called power generator, for your commercial vehicle equipment. Through our years of experience, we have built up in-depth knowledge, which allows us to always offer the ideal solution for your commercial vehicle.
Trust our experience and let us install the suitable power group that perfectly supports your operational needs.

Fixed mounting or removable units
Whether you need a 230V or 400V power supply, we offer solutions to fit your specific needs. Choose between fixed mounting with outlet through a heat-resistant floor passage or go for removable units, depending on your preference and space requirements.

Compressor
Carval provides the appropriate compressor for your commercial vehicle equipment depending on your specific needs. We take into account the desired air flow rate and air pressure requirements. The compressor is always mounted on vibration dampers in the cargo area, for efficient operation and a quiet and stable working environment.
Choose our compressors and experience reliable and efficient compressed air supply in your commercial vehicle.

Combination power pack and compressor
For intensive tasks such as heavy on-site welding or long-term operation at high power, a battery and inverter can have limitations. In such situations, a power generator combined with a compressor offers the ability to deliver significantly higher power outputs. With this powerful combination of generator and compressor, you can meet even the most demanding needs.

Air reservoirs
Additional air tanks can be incorporated in the cargo area or under the vehicle chassis, allowing you to work autonomously for longer.
Outlets & Power Reels (hydraulic, air and electrical)
In the cargo area, we can provide electrical reels or power outlets at your designated location for a power supply that is completely tailored to your workflow. Cable length and cable section are accurately sized to the installation, for optimal efficiency and safety.

We help you find the energy installation that suits your operations
If you do not have a clear view of the installation that best suits your needs, we can conduct an analysis and develop a customized proposal.
We go beyond our own installations. Existing installations, implemented by other parties, can be optimized by Carval. Using advanced data loggers, we analyze the current installation and work with you to adjust the configuration to make your system work optimally.
