Marine Electrical Power Systems
Power systems that safely and effectively integrate all components to support the electrical needs of your vessel in the most cost effective manner.
The information on this site is by no means comprehensive, but will hopefully provide a basic knowledge level on the subject. If would like to discuss your project or a current issue with your boat's power system, feel free to contact us by email or telephone. Contact Us
Electrical Requirements - Understanding the power needs of a vessel is usually dependent on its use as well as the systems to be supported. For example, does the boat spend most of its time connected to shore power at a marina dock or is it anchored for long periods, requiring electrical self-sufficiency. Most boaters understand they may need more capacity, but may not know exactly how much or the benefits from adding renewable energy. The process to figure this out is not that complex. Our Electrical Requirements Page will take you through this process.
Budget - While most marine contractors would like to have you believe that maintaing a boat is necessarily an expensive proposition and you should be prepared to fork over an exorbidant sum for everything they touch, that does not have to (always) be the case. Conversely, buying only the lowest cost components and having an inexperienced installer can lead to premature failure and much higher costs down the road. The key is to design your system to support your real needs, selecting the components that can provide them cost-effectively and installing them in a manner that maximizes their life, reliability and output
System Design - The most important aspects of a marine renewable marine power system are: 1) Sizing the system to meet your electrical needs and your budget, 2) Locating the panels and turbines to maximize their output and safety, 3) Sizing the components and wiring to minimize losses, and 4) Designing the mounts to be structurally sound and as protected as possible. Personal safety and potential damage to the boat should take precedence here, but all are important. Even what appears to be a small, low voltage system, can generate enough power to cause a fire or in the case of the wind turbine, cause serious injury. The System Design Page will give you more detail. If you have more questions, feel free to Contact Us. We are happy to discuss your project, and if you want, help you with the specifics of your design.
Installation - Many boaters are handy enough to install their own systems. If you are contemplating this, there are some issues you need to consider: Solar panels are very sensitive to shading, even small amount, so selecting the right location is critical; Wind generators can transmit a lot of vibration/noise to the hull so their mounts should be properly designed, and like a solar panel, location is critical so they receive undisturbed air flow. Proper equipment selection can have a significant effect on output, so do your research. Proper equipment matching and location selection can double the output of a poorly designed system. You may be dealing with a lot of electrical power, so a poor installation be a serious fire or safety hazzard. If you are not very familiar with marine electrical power systems, please enlist the help of someone who is. If you are comfortable with all this, you can save a lot by doing most or all of the work yourself. If not, you may want to consult with a professional that can provide services from reviewing your design to providing a turnkey installation
