Solar energy has the environmental protection and long-term cost savings, so that solar energy into many homes, but have you ever thought about the boat on the amp problem, below we will solve for you how to use solar panels to charge boat batteries and related issues.
1.Choose the right solar panel: generally, for small boats, 300watt solar panels can be used for it, but for large boats, it is more recommended to install 500watt solar panels.
The weight capacity of the boat is also a factor in the selection of solar panels. If 300 watts of solar panels, may lead to solar panels of power generation is not enough for the ship to use, then we have to increase the number of solar panels, but this makes the solar panels of the overall weight will also increase, the pressure on the ship’s load-bearing also increased, it is recommended that you choose to install a 500-watt solar panels can reduce the pressure on the ship.
It is recommended to install monocrystalline silicon solar panels on the boat, compared to polycrystalline silicon solar panels, monocrystalline silicon solar panels have a higher power generation efficiency, which is suitable for boats with high power usage. In addition, for the temperature on the water, humidity, etc. are factors to be considered when choosing solar panels.
2. Preparing other components for charging boat batteries with solar panels: A complete solar charging system requires an inverter, a battery management system, and the necessary wiring in addition to the solar panels.
It is best to choose an inverter that contains a solar charge controller module, otherwise, you will have to buy the solar charge controller again. The inverter converts the DC power into AC power, and then you can charge the boat batteries. Note in must ensure that the inverter power rating is close to the output power of the solar panels.
The battery management system controls when the battery starts charging by measuring the voltage and current of the battery, preventing the battery from being overcharged or over-discharged and prolonging the service life of the battery.
3. Choose a suitable location: First of all, consider a place with direct sunlight and no shade, preferably on the roof of the boat, of course, in addition to the roof of the boat, the bow and stern can also be. However, it is not recommended that you mount the solar panel directly in the middle of the deck, even though your boat may be big enough, it still increases the risk of being bumped by the solar panel.
4. Fixed solar panels: bracket fixing to choose a stable structure of the bracket, the boat will inevitably have water, will increase the probability of metal components rust, try to choose stainless steel or aluminium alloy. Sticky fixed using high-strength glue for sticking solar panels, will reduce the resistance of the boat traveling process, but its stability is not as good as the stent, generally flexible solar panels.
5. Connect all the components: The connection of the assembly is the most important step, if you do not connect the components, you have to spend time to check the components again to see if there is any problem. Pay attention to the positive and negative terminals of the batteries when connecting the marine batteries.
6. Check if the charging is normal: When using solar panels to charge marine batteries you should first use a battery tester or voltmeter to check the voltage of the marine batteries, which can reduce the risk of damage to the marine batteries caused by the failure of the solar panels.
Quiet and low clean-up cost: For yachts, solar panels are a good choice because there is no noise when solar panels are generating electricity, which will bring a quiet environment for visitors. Cleaning of solar panels does not require a professional, you can clean the dirt on the solar panels yourself using a cleaning brush.
High independence: Using solar panels to charge the boat’s batteries eliminates the need for the boat to go back to shore for charging. Especially when the boat is traveling in areas far from the power grid, there is no need to worry about the boat’s power supply.
Cost Savings: Using solar panels to charge the boat’s batteries reduces the boat’s dependence on the grid and saves on electricity costs. For boat owners who use their boats for long periods of time, this type of charging has a great advantage.
Keep the boat battery dry: It is normal for water to seep into the cabin when the boat is running. However, there should be no water in the boat battery attachment. Part of the reason is that water can cause the battery to burn out and leak, and part of the reason is that electric shock may occur.
Avoid overcharging and discharging: both overcharging and discharging can cause damage to the battery, affecting its life and performance. Try to charge your marine battery when it still has some charge left in it in order to extend the life of your marine battery.
Regular cleaning of solar panels and batteries maintenance: Using solar panels on the water, there may be condensation on the solar panels to form scale needs to be cleaned in a timely manner, marine batteries in the use of the process of the surface will fall on the dust, increasing the risk of electrical conductivity, but also need to be cleaned in a timely manner.
Using solar panels to charge your boat batteries is a practical and affordable way to reduce your boat’s mobility and make your experience more convenient.
