Can you run boat AC on battery?

Yes, you can run your boat AC on battery power. Standard marine AC systems typically require 115V or 230V, with 115V being the most common. While you can use a regular 12V battery to start the AC, you’ll need either a special inverter or a higher voltage battery to power the system on a regular basis.

The inverter size you would need would be dependent on the power requirement of the AC Unit and other onboard equipment. Most AC units are rated in BTUs/hr (British Thermal Units per Hour). To determine the inverter size, you’ll need to add the wattage of the AC unit to the wattage of any other onboard equipment that you plan on running in addition to the AC at the same time, and then divide that total wattage by the inverter’s voltage (most inverters run at either 12V or 24V).

If in doubt, you should always err on the side of caution and choose a larger inverter. In addition, it’s important to keep in mind that a standard 12V marine battery won’t be able to power your AC for very long.

To run for more than a few hours at a time, you will likely need multiple batteries, and/or a battery booster such as a generator or solar panel.

How big of an inverter do I need sailboat?

Your sailboat’s inverter size will depend on its power requirements, as well as your particular needs. A good place to begin when determining what size inverter to get is to calculate the wattage requirements for the electrical appliances and systems that you plan to use on your sailboat.
