How to manage the 12V & 220V electrical system

WHEN THE BOAT IS ON SHORE POWER (220V)

• There is a main switch on the 220V panel and 3 more ( one for the sockets , one for the battery charger and one for the boiler )
• The battery charger can keep your batteries in a good level so you don’t have to worry about the energy consuming by the fridge, the lights etc.
• You can have 220V power at all the sockets
•  DO NOT RUN THE ENGINE AT THE SAME TIME  (the isolator will get damaged )

WHEN THE BOAT IS OPERATING ON 12V

• There is a main switch for the engine battery
• There is a main switch for the domestic batteries
• When  you don’t run the engine you have to be very careful on energy consuming especially with the fridge which consumes a lot
• Take a look at batteries’ level. If the level is below 12.0V  you have to charge the batteries .
• The proper level when the engine ia running  is 13.8V that means that the alternator works properly 
• Do not let the batteries’ level go below 12V
• If you run the engine you can use anything you  like as the alternator provides the system with 12V
• If you want your batteries to get charged by the engine you have to run the engine at 1500rpm
• Even you run or not the engine you can’t have 220V at the sockets if the boat is not connected with shore power
