The essential circuits of the direct current consumers are:
position lights
interior and deck lighting
electrical devices
220 V devices via current converters (according to the contract specification)
The interior and deck lighting consists of energy-saving halogen or fluorescent lamps and requires
relatively little power. The navigation electronics also require very little power. Nevertheless, you
should turn off the consumers you no longer need as soon as possible. This can also be done
centrally from the central control panel.
If, for certain reasons, it is not possible to recharge the batteries at sea, you must be economical
with the electrical energy. Nautical lighting has absolute priority. In case a capacity bottleneck
occurs due to a failure in the supply, all other consumers must be switched off first.
We recommend switching on the consumers according to their importance:
at night only the position lights
chart table lighting only when it is used
switch navigational instruments to “stand-by” if possible
VHF radio only in critical situations
Note: If an autopilot is installed, it can consume a lot of power,
especially when sailing in heavy swell, because the hydraulic steering
pump may have to carry out significant steering corrections
depending on the swell conditions.
The general lighting should also only be switched on when necessary. One should dispense with
the refrigerator box, the heating and other consumers that require a great amount of energy.
Remember to recharge the batteries when at sea, as well. Running the engine while sailing can
recharge the batteries up to the desired state so that the next most important consumers can be
switched on.
In case of malfunctions, you should check the electrical systems and installations to find out the
reason for insufficient charging.

The gel batteries require little maintenance and should be well charged at all times. Please regularly
check if this is the case.
In the winter season it is necessary to store the well-charged batteries in a dry and frost-protected
place. Take care that the poles are clean and protected against corrosion with pole grease.
