Overview: Modified Sine Wave Power Inverters represent the most economical solution for powering a large number of appliances. The waveform produced by a Modified Sine Wave Power Inverter is “blocky” resembling a set of steps whereas the waveform produced by utility companies is smooth much like a curvy road. Therefore because of the type of waveform the Modified Sine Wave Power Inverters produce they are suitable for most applications. Modified Sine Wave Power Inverters are more efficient in converting battery power to AC. So if you’re looking to make a pot of coffee run a heater or air conditioner or appliances that can withstand occasional electrical noise a Modified Sine Wave Inverter is a cost-effective solution. To select the right inverter first determine what devices you would need to run in the event of a power outage. Then select the appropriate inverter that can carry the combined wattage requirements of these devices. Some appliances have a start up amperage. To see a list of average start up requirements see our Technical Support section on the left nav bar of our website. At AIMS you’ll discover our inverters range from 75 watts up to 12000 watts – more than enough to power nearly every application imaginable. /This 400 watt inverter is ideal for small devices.
