About us
We started Camper-Elektra.com in 2021 to help vanlifers in the Netherlands build safe and reliable electrical systems. Since then, our platform has supported thousands of DIYers with clear, custom wiring diagrams. We’ve seen how challenging it can be to design a safe setup — that’s why we developed easy-to-use software that takes the guesswork out of van electrics.
Let me explain all the possibilities ⤵️
User Friendly easy to use software - For beginners and professionals
Whether you’re building your first camper or designing complex setups for clients*, our software makes it easy. The intuitive interface guides you step by step — no guesswork, no jargon. From choosing the right components to safe cable sizing, everything is clearly laid out. So you can focus on your build, not on figuring out the tech behind it.

Selection of the AC and DC voltage
Step 1: Choose your system voltage
This is the main voltage your setup will run on. Most people choose either 12V or 24V — just pick the one that fits your build best.
Step 2: Select your alternator voltage
This is the voltage of the alternator in your vehicle. Again, you can choose between 12V and 24V.
Step 3: Pick your AC voltage
This sets the voltage for your AC input and output. You can choose 230V or 120V. For example, if you’re in the UK, go with 230V — this won’t affect your wiring layout.
Busbar and battery selection
Choose your busbar setup
Next, you’ll decide how the different parts of your system are connected. You can choose between using individual busbars — which are separate connection points — or a Victron Lynx Distributor, which combines everything into one neat, organized unit.
Select your battery type and quantity
Now it’s time to choose the type of battery you’ll use in your setup. You can select from common options like Lithium or Lead Acid — whichever suits your needs best. Not sure yet? No problem — just pick “Not sure yet” and you can decide later. After that, choose how many batteries you plan to install. The system supports up to five.
Alternator charging
Choose how to charge your household battery from the alternator
In this step, you’ll select the type of charger you’d like to use to charge your household battery while driving. There are two main options:
A DC-DC charger, which is safe and ideal for modern vehicles
A Victron Cyrix relay, a simpler option that connects the batteries when voltage is high enough
If you choose a DC-DC charger, you can then select whether you want an isolated or non-isolated charger.
Based on your choices, there are quite some compatible chargers. You can find the full list here.
Battery monitoring
Battery monitoring
Now you can choose whether you want to monitor your battery. Some lithium batteries have a built-in battery monitor — others don’t. If yours doesn’t (or if you want extra insight), you can add a monitoring device. You have four options:
- No Battery monitor
A Battery Monitor
A Victron SmartShunt
A Victron Cerbo GX
Each option offers a different level of detail and connectivity, depending on how closely you want to track your system’s performance.
Battery protection
Add extra protection (optional)
If you want to build in some extra safety, there are two options to consider.
First, you can add a BatteryProtect device. This helps prevent your battery from discharging too deeply, which is especially important for lead-acid batteries. For lithium systems, this is usually not necessary — so we only recommend it for lead-acid setups.
Second, you can choose to install an isolator switch between your 12V or 24V appliances. This gives you more control over your system.
Inverter selection
Choose your inverter or inverter/charger
Based on the DC and AC settings you selected earlier, you can now choose from a range of compatible inverters or inverter/chargers.
You have several options:
No inverter
A basic inverter (W)
- A Victron Inverter (VA)
A Victron MultiPlus
An Ective SSI (And Pro version)
An Ective CSI (And Pro version)
The maximum recommended inverter size is 3000W. The largest supported MultiPlus model is the Victron MultiPlus II 24/5000/120-50.
You can find a full list of compatible models [here]
Solar panels
You can add up to five solar panels to your system, with panel sizes ranging from 90W up to 500W. Whether you’re planning a small setup or a more powerful array, the system gives you the flexibility to design it your way.
You’ll also be able to choose how to wire your panels:
In series, which increases voltage
In parallel, which increases current
Based on your panel configuration and system settings, the software will automatically select the right MPPT solar charge controller for you.
For extra safety and control, you can also choose to add a solar isolator. This allows you to disconnect your solar panels manually when needed.
