Your motorhome becomes intelligent – control via Bluetooth
Many campers rely on a self-sufficient power supply, be it through powerful on-board batteries or solar cells on the roof. But the question usually remains: Will the charge level be sufficient for the next night? Is the solar cell really charging optimally? And how long will the power last? This is exactly where the ONDA Smart System comes in.
With a Bluetooth connection between your motorhome and your smartphone, the ONDA Smart System app shows you all relevant data on charge status, consumption and energy supply in real time. The first devices will be launched on the market in the second quarter of 2025 – perfect for anyone who wants to make their motorhome smarter and more efficient.
Intelligent battery management – so you don’t run out of juice on the go
A central element of the system is the Battery Duo System (BDS200). It manages two 12-volt batteries simultaneously, even if they are of different ages. The maximum load per battery is 100 amps. If one of the batteries is faulty, the system automatically detects this and isolates it – you receive a message on your smartphone.
Advantages of the BDS200:
- Precise calculation of the remaining time and state of charge
- Supports both lithium and lead-acid batteries
- Bluetooth data transmission to the ONDA app
- Automatic fault detection and warning messages
Optimal use of solar power – more efficient charging with MPPT technology
If you supply your motorhome with solar power, the PRM400 solar controller gets the most out of your solar modules. Thanks to MPPT technology (Maximum Power Point Tracking), the energy yield is increased by up to 20 % – compared to conventional PWM chargers.
What does the PRM400 do?
- Optimizes the charging power of your solar system
- Supplies lithium and lead-acid batteries particularly gently
- Can display the data via the app or a permanently installed panel
This way, you can be sure that your motorhome is always charged with the maximum possible solar energy.
Full control over consumption and remaining time

In addition to the power supply, the current consumption is also crucial. The AM500 switching relay measures and analyzes the power consumption and calculates the remaining runtime of your on-board batteries.
With a capacity of up to 500 amps, you always have your power supply in view.
The best thing is that all devices in the ONDA Smart system work wirelessly via Bluetooth. This eliminates the hassle of laying data cables. You can therefore easily integrate the modules into your existing system.
Conclusion: Smart power supply for your motorhome
With the ONDA Smart System from AL-KO VTE, you get a smart solution for monitoring your on-board power supply in real time. Whether you are self-sufficient or on the road, you can always see how long your power lasts and how efficiently your solar cells are working. The simple Bluetooth connection makes installation child’s play without any annoying cables.
The first devices will be delivered from the second quarter of 2025 – perfect for anyone who wants to make their motorhome fit for the future!
