What is a Power Inverter?
A power inverter converts DC power or direct current to standard AC power or alternating current, which allows you to run electrical equipment off your car or marine battery for mobile applications, emergencies or simple convenience. Power inverters are small rectangular devices that have a trailing wire with a jack that plugs directly into the cigarette lighter on the dashboard. They might also come with jumper-like cables for connecting directly to a battery. The device normally has one or two outlets for standard electrical cords. Your laptop, small-screen television, video game player or portable DVD theater are all examples of devices that will get you through a long ride, assuming you’re not the one driving! Power inverters are great for camping at parks that do not provide electricity. The toaster, blender, and boom box can all still be used. On your boat you can plug in the digital movie camera to capture those great water-skiing videos you might have missed after the camera’s
As mentioned in my articles on solar power basics and solar panels, the current produced by a panel (and consequently from a deep cycle battery) is DC (Direct Current). While there’s many appliances available that will run directly from DC; most household appliances that you plug into an ordinary wall socket require AC (Alternating Current). In order to switch the current type, you’ll need a power inverter. The inverter sits between the solar panels and your mains wiring in a mains grid connect system, or between the batteries and your appliances in a stand alone power setup. In the case of grid connect, the inverter feeds any surplus power your panel has generated directly into the power grid for use by other customers – no; the utility doesn’t get it for free – you get a credit for the electricity you’ve contributed, and in some countries you’ll even get paid extra!

A power inverter is a device that converts DC (Direct Current) power into AC (Alternating Current) power. The AC output is usually 120 VAC, 60 Hz (USA domestic power) or 230 VAC, 50 Hz (International power). Aircraft applications often require 115 VAC, 400 Hz. Nova Electric offers all three of these common output voltages, in both single and three-phase configurations, as well as other special / custom outputs.
