Inverters

An inverter converts 12V power from a battery to 230V power (virtually the same as comes out of a domestic 3-pin plug socket at home.) This will allow you to bring a few of your creature comforts from home on the boat with you!

Below is a rough size guide for what inverter you would need to run the appliance of your choice.

 
How much battery will it use?

When hooked up to 240v shore power in a marina you are sharing the same earth as all the other boats. If some of those boats have worn out or missing anodes then they will be using YOURS!, or even worse your hull or outdrives. When connected in the earth lead of your shoreline this device will protect you against that problem.
