All from a single source
Chargers are necessary for a complete and efficient charge of your on-board batteries, regardless of the energy source. An optimum charge maximises the service life of the batteries.
Charging booster supply consumer batteries with energy while driving and can be used as jump starters.
Inverter convert 12 V DC voltage into 230 V AC voltage and are ideal for sensitive electrical appliances thanks to their pure sine wave.
Weatherproof solar panels and MPPT charge controller enable a self-sufficient power supply and the efficient use of solar energy.
With intelligent Battery monitorswhich can be operated via app, you always have an overview.
With these components, you ensure maximum flexibility, self-sufficiency and efficiency - perfectly tailored to the needs of your customers.

Two different types of battery can be found in motorhomes. The starterbatteries, which are responsible for starting the combustion engine, and the Supplybatteries that supply the lighting, refrigerator, radio or television, for example, when the engine is switched off.
Both battery systems are charged while the engine is running.It is important that the battery systems are disconnected from each other when the engine is switched off so that, for example, the TV does not drain the starter battery and it is then not possible to restart the combustion engine and alternator.
The use of a starter battery for the supply of consumers in the caravan is generally not recommended. Starter batteries are designed for short-term power output so that they can be recharged immediately after starting the combustion engine. Supply batteries are designed for cyclical loading. They can be used over a longer Period relative emit low currents.
The supply batteries with AGM technology are particularly versatile and the best choice in combination with an inverter.
Gel batteries are the most popular on the market for supplying electrical consumers in the caravan/marine sector. They are easy to transport and can withstand long periods of storage.
Lithium iron phosphate batteries are becoming increasingly popular, particularly due to their low weight and high energy density. The higher purchase costs are offset by a long service life thanks to excellent cycle stability.
The specification C10 or C20 is always linked to the battery capacity in Ah. Two values are often given:
e.g.: 225Ah (C10) and 242 Ah (C20)
This means that the battery can deliver more power if it is used for more than 20 hours. The faster the battery is discharged, the less current it can deliver.
If you are currently using a liquid battery and are considering a conversion due to the maintenance-free, non-gassing, longer service life and higher capacity, you should first clarify whether the existing battery is suitable.e charger is also suitable for AGM or gel batteries. At the same time, you should bear in mind the operating conditions.
Those who Supply baseIf you only use your batteries a little, you can probably get by with the inexpensive liquid version. If, on the other hand, you plan to use your batteries more cyclically and expect a high power requirement, you will probably be better off with the cheaper liquid variant.d will not be able to avoid retrofitting in the long term.
Lead supply batteries last a very long time if they are always full as often as possible and are discharged as little as possible. The following standard errors occur again and again in practice:
- The batteries are so large that the charger, wind generator or solar panels do not provide the necessary charging current to fully charge the batteries. This damages the batteries in the long term. The capacity decreases. A charger that is designed for the battery capacity provides a remedy.
- The batteries are too small. The loads draw so much current from the supply batteries that a deep discharge occurs and the batteries are damaged. In this example, the battery capacity needs to be increased.
The following sample calculation can be used to roughly determine the required capacity (Ah) of your battery system:
Power (W) / voltage (V) = amperage (A)
Amperage * utilisation time/day = required capacity (Ah)
Example: 60 W / 12 V = 5 A
5 A * 10 h = 50 Ah
Using this calculation, you can calculate the consumption individually and determine the total capacity required by adding them together. As the usable capacity is not equal to the specified capacity, the calculated capacity must be multiplied by a factor depending on the battery type.
In this case, we suggest the following factors:
50 Ah * liquid battery factor 1.7 = 85 Ah
50 Ah * factor AGM & gel battery 1.4 = 70 Ah
While travelling, the on-board batteries are charged by the engine's alternator. However, an optimum full charge is usually only achieved using a charger with a 220 V connection. For this reason, every opportunity for charging should be utilised. Wind generators and solar panels are usually only used for supplementary charging, i.e. a charger is required to optimally charge the batteries and thus maximise their service life. We will be happy to help you select a suitable charger.
Be careful with the different batteries! For acid, gel, AGM and There are different charging technologies for lithium batteriesen. An incorrect charger can damage the battery and, in the worst case, can lead to an explosion. Always seek advice!
