Choose your energy section.
Explore the parts of your electrical system and go straight to what you need. If unsure where to start, calculate consumption before comparing capacities.
The quick answer
Capacity, output and charging: decide on all three.
Wh describe stored energy; W describe instantaneous power. You can have a large battery with inadequate charging, or a powerful station with insufficient energy for several days. For portability, consider a power station. For an integrated fixed system, compare the auxiliary battery, chargers and protection as a whole. Start with the consumption calculator ↗

How to choose energy for a camper with a real calculation.
1. Calculate daily consumption
Write down the devices, their power and the time of use. As a starting point, energy in Wh = power in W × hours. For equipment that cycles on and off, such as a refrigerator, use a measured consumption or an estimate representative of the entire day. Avoid multiplying the maximum power by 24 hours without considering its operation.
2. Distinguish output power from runtime
A 600 W power station may run a device within that limit, but the rating does not tell you how long. Runtime depends on usable energy and consumption. Include conversion losses and simultaneous loads; also check startup surges and each output's limits.
3. Convert Ah to Wh correctly
To compare batteries, multiply Ah by the nominal voltage on the specification sheet. For example, 100 Ah × 12.8 V = 1,280 Wh nominal. Your appliances will not receive all of that energy: discharge allowance, losses, temperature and usage conditions affect the result.
4. Plan to recharge before expanding
A larger battery stores more energy but may take longer to charge. Consider driving time, available sunshine and external hook-ups. Choose chargers for your battery and vehicle; a solution that works for another model may not suit yours.
5. Check solar compatibility
The panel must respect the voltage range and current and power limits of the regulator or station. Check Voc, temperature, polarity and connectors, in addition to wiring. Two devices with XT60 or MC4 are not automatically compatible. You should also not connect a panel directly to a battery without the appropriate regulation system.
6. Allow for space and installation
Measure the available space, assess weight and allow the ventilation and access specified by the manufacturer. In a fixed installation, size batteries, cables, protection and charging equipment together. Use each device's instructions and qualified professional support when designing or modifying it.
An example to put the figures in order
If your loads total 500 Wh a day, two days without charging mean 1,000 Wh of planned consumption before losses and operating margin. This does not mean any 1,000 Wh battery will cover it. Nor does a 200 W panel constantly produce 200 W: output changes with sunlight, orientation and shade.
Inverter and DC-DC charger: different functions
The inverter converts battery DC into AC for compatible appliances. The DC-DC manages charging from the vehicle system to the auxiliary battery. Choose according to voltage, chemistry, alternator, currents and protection; buying both by rated power alone is not enough to design the installation.
Monitoring and control: understand your consumption
A monitor helps track inputs, outputs and state of charge. A battery or station app displays the data supported by that device, which may not cover all campervan loads. Check what you need to measure and how to install and calibrate the chosen system.
Your questions answered
Frequently asked questions
Is an auxiliary battery or a portable power station better?
A power station combines a battery, electronics and connections in a portable unit. An auxiliary battery is part of an installation requiring chargers, protection and distribution. Decide according to consumption, integration, total budget and whether you need power outside the campervan.
Is a 100 Ah battery enough?
Capacity alone cannot tell you. Calculate daily consumption, desired runtime and available charging. Compare in Wh using nominal voltage and allow for usable energy and system losses.
Can I connect any solar panel to any power station?
No. Check voltage range, Voc, current, permitted power, polarity and connection. A plug fitting does not prove compatibility. Follow the power station manufacturer's limits and accessory requirements.
Does the BMS replace installation fuses?
No. The BMS manages and protects the battery within its functions, but does not replace the protection and sizing needed for external cables and circuits. Design the installation as a whole.
How much energy does a 200 W solar panel produce per day?
The 200 W rating refers to test conditions. Daily energy production varies with location, season, orientation, shade, temperature and losses. For sizing, use a reasonable local estimate, then check actual production.
Can I charge a LiFePO4 battery with my existing charger?
Only if both charger and battery manufacturers confirm compatibility and suitable parameters. Check voltage, current, charging profile and temperature conditions. Do not assume a lead-acid charger is suitable simply because it shares the 12 V label.
