Self-sufficient power supply – independent with solar energy, storage & system technology
With a self-sufficient power supply from Solarkontor , you become independent of the public power grid. Whether in a motorhome , boat , garden shed , or off-grid system – here you'll find all the components you need to efficiently generate, store, and safely use solar energy. Our systems combine solar panels , inverters , charge controllers , and batteries into a smart, comprehensive solution for maximum energy independence.
Whether you want to set up a mobile system in your camper or equip your home with its own power grid – at Solarkontor you will find high-quality, tested technology for your self-sufficient energy supply .
What does self-sufficient power supply mean?
A self-sufficient power supply refers to an independent energy system that generates and stores electricity without a connection to the public grid. Energy is captured using solar panels , stored in batteries via charge controllers , and converted into usable alternating current by inverters . Additional components such as DC-DC converters , chargers , and monitoring systems ensure maximum efficiency and safety.
This is how you build your own self-sufficient power supply
- 1. Energy generation: Via solar panels or other sources such as wind or generator power.
- 2. Charge controller: Regulates the voltage and protects your batteries from overcharging.
- 3. Energy storage: Modern LiFePO4 batteries store electricity safely and efficiently.
- 4. Inverters: Convert the stored direct current into 230V alternating current for household appliances.
- 5. DC-DC converters & chargers: Optimize voltages for different consumers & charging sources.
- 6. Monitoring: Keep an eye on energy flow and consumption in real time.
Typical applications
- Motorhome & Vanlife: Electricity for lights, laptop, refrigerator & e-bike – independent of the campsite.
- Boat & Marine: Reliable energy at sea for navigation, lighting & comfort.
- Garden shed & weekend house: Off-grid power supply – clean & quiet.
- Off-grid systems & emergency power: Secure operation even during power outages or in remote regions.
Advantages of an independent power supply
- Independent of the power grid and rising energy prices
- Clean & sustainable through solar energy
- Flexibly expandable through modular components
- High efficiency through coordinated system technology
- Ideal for camping, home & off-grid applications
Balcony power plants – the easy entry into energy independence
For many, a balcony power plant is the first step towards generating their own electricity. These compact plug-and-play systems are easy to install, require no permits, and deliver direct solar power for self-consumption. Ideal for apartments, balconies, and small households – simply plug it in and become more independent.

FAQ | 7 frequently asked questions about self-sufficient power supply
What exactly does self-sufficient power supply mean?
Self-sufficient means independent – you generate, store, and use your own electricity without being connected to the public grid. Perfect for campers, garden sheds, or remote locations.
What components do I need?
A complete system consists of solar panels, charge controller, battery, inverter, and optionally a DC-DC converter, charger, and monitoring system. All components must be compatible.
Can I retrofit an existing system?
Yes, many systems are modular. You can add solar panels, batteries, or inverters later to achieve more power or capacity.
Which battery is best suited?
For high efficiency, we recommend LiFePO₄ batteries. They are lightweight, safe, fast-charging, and last up to 10 years – ideal for solar and off-grid systems.
Are there also solutions for apartments or balconies?
Yes, balcony power plants are the simplest form of self-sufficient electricity supply for your home. They can be connected without any electrical installation and directly reduce your electricity costs.
How long does a self-sufficient power supply last?
With high-quality components such as MPPT charge controllers, LiFePO4 batteries and pure sine wave inverters, your system can run reliably for many years.
Is an independent power supply expensive?
The costs depend on performance and capacity. Small sets for campers start in the low three-figure range, while stationary systems can cost several thousand euros – but pay for themselves in the long run through electricity savings.
