Insufficient current on board is a source of sailors lasting concern, and an in-search for an accessible electric harness affects the planning of sailing and sailing in ports that might not be sailed. However, the need for power on a motorboat can be met by engine operation or with an additional aggregate, but it is inconceivable to stay in a quiet bay and increase fuel consumption.
On board, most sailors want to have the possibility of a long-lasting supply of the entire ship system with no generator or port connection. So far, the ship has gained electric energy in these two ways. But when the boat was resting on the anchor away from the current on the shore, the generator had to be activated. At night, on some remote and quiet anchorage, the noise did not disturb only the mood of the crew, but of other nautical sailors nearby. On a comfortably equipped motor boat that sails has lighting, refrigerators and electronic equipment that would spend electricity and fuel generators. And with low consumption, for the most desperate needs, the generator was rolling all night … And it is well known that the generator does not even use the least load and proportionally less fuel. This gave birth to the idea that the generator should be switched off from evening to morning, and the refrigerator and other needs should be satisfied from the silent sources. When the engine and boat are switched on, and the generator is switched on, it is also possible to charge the battery pack more abundantly. There are two benefits to this: while the engine generator operates with a higher degree of utilization of the energy produced per liter of fuel, at night, with the silent energy of the battery, all important boat systems can be maintained, and a lot of those intended for comfort or entertainment. Of course, there is a need to power up the electricity connection with marine battery, and so the ship prepares for longer sailing and carefree anchoring on remote parts of the coast.
To achieve these goals, it is not enough to have conventional bulk marine batteries designed to cover the most demanding and elemental safety requirements. The ship shall be equipped with a generous battery bank for storage of electricity, and such installation shall be accompanied by devices for efficient charging, constant control and monitoring of the condition of the
battery and thus have a controlled discharge.
The importance of marine battery monitor is cruital. A system to monitor and control the state of the marine battery, the usage of the power and remaining work time of the battery is important. To be able to monitor the usage of current charge and discarge of the marine battery. Monitors are ussually equipped with alarm systems to ensure you never run out of electricity. The aggregates can be turned on to refill the battery before its depletion.
Nowdays the marine battery monitors are almost a must have on every battery using vessel on the sea.
