Batteries & Charger & Inverter
It is essential for a boat to operate healthily and efficiently at sea. Therefore, it is important to choose batteries that offer the highest performance and effectively store the energy obtained, whether for the engine battery or the service battery.
In the marine sector, marine batteries should be preferred as gel batteries instead of older technology batteries. Gel batteries are more deep-cycle compared to other batteries and do not contain any liquid. Boats can be subjected to considerable turbulence and may be in choppy waters for extended periods. In such situations, the batteries inside the boat can leak liquid, which may cause short circuits and lead to battery failure. Battery failure while underway is a serious issue that can result in more severe consequences. Therefore, with the advancement of technology, more efficient and lower-risk gel marine batteries have been developed.
If the boat is in the marina or on land, identifying and addressing potential faults is easier. However, while sailing in open waters, this process can be more difficult, and the fault may not be resolvable. For this reason, choosing a long-lasting and maintenance-free battery for the electrical supply will be beneficial. This way, our journeys will be safer and more comfortable.
Marine batteries are designed and manufactured to withstand extreme hot and cold environments. Additionally, marine batteries have a longer lifespan than batteries produced for automobiles. Since marine batteries are maintenance-free, there is no need to add any liquids or electrolytes. Due to the harsher and more turbulent conditions at sea, marine batteries are resistant to shocks and vibrations.
As Daphne Marine, we calculate the energy requirements of your boat to ensure that your equipment operates efficiently and as uninterrupted as possible. Based on these needs, we provide battery supply and installation services.
Charger
Sinusoidal alternating electrical energy is converted into the direct current energy we refer to through semiconductor devices such as thyristors and diodes, as well as devices that charge batteries with this direct current energy.
The devices have measures in place to prevent leakage and grounding faults at the output, minimizing vital risks to zero levels. If desired, residual current devices (RCDs) can be used with these devices.
In all our rectifier systems, safety equipment is used flawlessly and completely, and above all, this equipment is of great importance to our company and is utilized in its entirety without reducing costs.
The most important components of rectifiers are the rectifier groups. In these groups, the aluminum sections that serve as coolers and the working currents of the diodes are very important, so their percentage values must be calculated very accurately. The devices should be able to operate smoothly at a minimum efficiency of 90% without having to stop their functions due to overheating. Battery charging rectifiers are specially designed for each type of battery because the supply voltage and percentage charging current vary according to the type of battery.
Battery charging rectifiers should have a minimum charging frequency of 100 Hz. The peak voltages for the battery group to be charged should be calculated accurately according to the battery type, and the float charge durations should be assessed between a minimum of 1 hour and up to 5 hours, with protection against overvoltage. This is because the most important point with batteries is to know the charging voltages well, ensuring they are charged in a way that does not damage the battery plates, and it is essential to avoid leaving the batteries discharged to prevent wear on the battery plates.
Inverter
The use of inverters on boats is quite common today. Simply put, an inverter is a device that converts 12 Volt DC current into 110/220 Volt AC current. Many of the electrical appliances used on boats operate on 12 volt and 24 volt DC current. However, it may not always be possible to find alternatives for every electrical appliance that works on 12 volt and 24 volt. Additionally, it should be noted that 12/24 volt electrical appliances are relatively more expensive compared to their 110/220 volt counterparts.
Before selecting an inverter for the boat, the most important task is to calculate how many watts will be consumed on board. Once the watt consumption has been calculated, our inverter selection should be higher than the total watts used.
However, it is important to focus not only on the calculated watt consumption but also on the assessment of surge load.
