Shore power systems, which allow you to connect to shoreside electricity, are a boon to amateur boaters. Included in most large vessels, shore power systems draw AC power into the boat that can then be used for your various equipment and accessories.

This type of system presents plenty of advantages. Using an onboard charger, you can maintain and recharge the boat’s batteries, which in turn feed all 12-volt equipment for prolonged periods of time, without draining the batteries or causing a power-out.

Like at home, shore power can be used for all your household appliances, such as TVs, microwaves, water heaters, etc. Wall outlets are useful for connecting these appliances, as well as phone chargers and more. Essentially, it helps bring a little luxury onboard!

Not all boats are equipped with shore power systems, however. If your boat doesn’t have one, rest assured that there are a few different solutions on the market – many of which are reasonably priced.

Installing a battery charger
The first thing you might want to consider doing is installing a marine battery charger on your boat. When you’re docked, it connects to a domestic outlet using a regular extension cord and can charge a couple of batteries to supply your 12-volt equipment. This is perfect for a sound system, electric cooler or other 12-volt appliance. A marine battery charger will ensure that you get all the power you need – something you’ll appreciate when it comes time to start up the engine!

Installing a charger is fairly simple, as there is often space for one in the engine compartment. Just screw the charger into place and connect it to the battery’s positive and negative terminals. Several types of charger exist; it’s up to you to determine which one suits your needs best and how many you require. You can also install a permanent outlet to make it easier to connect the charger to an extension cord – this option is also more attractive.

For added practicality, you might want to add an inverter to convert the boat’s 12-volt current into 120 volts or 230 volts. This will allow you to connect household appliances at a low cost.

A comprehensive solution
For those of you looking to cover more bases, there are shore power kits that are relatively easy to hook up. These usually include an Shore power inlet (to plug in the marine cordset), a small AC panel (to connect to a few domestic outlets) and a battery charger. Obviously, this involves a certain degree of handiwork, as you’ll have to install the shore power inlet and the AC panel, but at the end of the day you’ll have a shore power system for a fraction of the price.

EZ ACDC is one company that makes a good kit for an affordable price. It includes everything you need and installation is made easier with all the right connectors. It’s hard to go wrong with this system.

If you don’t feel comfortable tackling this project on your own, consider contacting a professional for assistance.
