12 Volt System

At the moment the only one and running - light, fridge, water, gas, 240V. All projects running with 12 V with DC-DC converters. The devices in Moment: 2 Raspberry PIs for Grundl-TV and Sat-Uplink, WIFI-AP - Router and WSPR beacons.

Voltage control 20V volt scale - here y see 10,9V at 10,5 the power shutdown

Lifepo4 - batteries 4 pcs 176Ah in a wooden box ca 20cmx20cmheight ca 40cm

The Lifepo4

Chargeing Lifepo4 4S 4 in serie. LIFEPO4 Charging from 12.2Volt to 14.4Volt.

The charging current and consumer current can be read off the black charge controller by the battery.

The 12V solar panels are the small ones hanging horizontally on the south side and the solar ZILLE(SMALL SOLARBOAT OUTSIDE) which should always be connected, it is important it brings 300W.

The main fuse is on the battery. Further fuse in the lounge behind the grey circle.

24V System

Currently out of service - these are the 2 large 250W solar panels which also hang vertically.

WHY ARE THE PANELS HANGING DOWN: Because we need most of the energy in winter when the days are short and the sun does not rise higher than 15 degrees above the horizon and furthermore the snow does not stay on it. Please no more discussions why they are not on the roof. DOTO the 24 volt panels could also be connected to the 12 volt battery via the existing charge controller. the charge controller is an MPPT system which is nothing other than a DC-DC converter. This means that optimal battery voltage is always generated.

The 24V batteries are NIFE batteries, indestructible Edison batteries. They are in a red metal box of approx. 120cm x 80cm and a height of approx. 40 cm.

This BAtterien was last used for lighting only.

Solar charging before LAderegler and BAtterien

24V and 12V solar panels can be switched on/off manually by the system in the “Red Cross” box in the lounge. In this “Red Cross” box there is also a working car cigarette lighter with various charging cables. If possible, always charge everything via the 12V charging cable, which saves electricity.

220 Volt

There is a 24 V and a 12 V inverter for 240 volts. The 12-volt inverter can be switched on and off with a switch on the companionway. Switching the inverter off saves electricity.

GAS

Basically - GAS in the ship

Gas is heavier than air, it sinks down and fills the space. Unlike a camping bus or a caravan, however, there is no opening at the bottom of the ship where the gas can escape.

Therefore PLEASE BE CAREFUL.

The gas is therefore switched off 3 times.

Gas regulator on the gas cooker:

12 o'clock off

9 o'clock full power

6 o'clock(stop) minimum power.

Switch on the gas flame:

Press on a gas regulator and set to 6 o'clock. Use a lighter to light the flame. alternate between 9 o'clock and 6 o'clock with the regulator until the flame burns nicely on all sides of the nozzle.

The gas bottle is on the outside of the sundeck in the left-hand metal box, and there should always be a spare bottle inside.

Water

In the water circuit, the pressure is always kept at approx. 3 bar via a pressurised water pump. This pressurised water pump is located by the sink and can be switched on and off at the control panel near the gas cooker via the black switch near the gas cooker.

UP ON - DOWN OFF.

Turning off the water is important because:

Heating

The heating system is a gravity heating system. This means that when the kitchen cooker is heated, the hot water rises, cools down over the radiators and circulates back to the kitchen cooker.

Service

Waste-holding Tank

The waste-holding tank is located directly under the toilet. The holding tank has a capacity of 750 litres.

Check the waste-holding tank from time to time to make sure it is full:

TODO the holding tank has an overflow, but it is too small and always clogs. The overflow diameter should be increased. The overflow can be found in the rear bulkhead.

Hot water

Hot water collector outside

Hot water boiler behind the grey circle.
