Input protection: Over voltage protection, low voltage protection.LED indicators for fault status and working status.Optional output voltage 220 or 230VAC by using DIP switch.Adoption of advanced SPWM technology, pure sine wave output.

Safe design with input and output electrical isolation.High power inverters also need very thick DC input power cables, so if they look thin on the images, it’s not likely to be up to the job.ĮpEver Pure Sine Wave Inverter – Features: There are reports that 75% of unbranded inverters cannot achieve anywhere near the specified power outputs. Beware of unbranded inverters which have very high wattage output and appear to be very good value. Sale of inverters is a long-standing and competitive market. In general, because the total harmonic distortion is higher in modified square wave inverters, motors will run hotter (less efficiently, consuming up to 30% more energy than with pure sine wave inverters). Pure Sine wave inverters should be used for televisions, laptops, digital microwaves, fridges and other sensitive electronic equipment. Modified inverters are best suited for resistive loads which don’t have a start up surge. In fact, some computers simply will not run off modified sine wave inverters. Modified sine wave is a simple form of power output adequate for simple electronics but may damage more complex electronics such as computers. See the image showing the two types of alternating current curve.īoth types of inverter will power your AC appliances but pure sine wave inverters are high quality (or better than) the power output in your home. There are two types of inverters, modified sine wave and pure sine wave. Inverters are also available to convert 24V or 48V DC into 240V AC, for example where you may have larger battery banks configured in series. This allows household items to be powered from a battery. An inverter takes a 12V Direct Current (DC) input of electricity, usually from battery storage, and changes it 240V alternating current (AC) power output, the same as mains power voltage.
