Epever 2000w Pure Sine Wave Power Inverter

What is an Inverter?

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. This allows household items to be powered from a battery. 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.

Pure Sine Wave is the Best

There are two types of inverters, modified sine wave and pure sine wave. See the image showing the two types of alternating current curve.

Both 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. Modified sine wave is a simple form of power output adequate for simple electronics but may damage more complex electronics such as computers. In fact, some computers simply will not run off modified sine wave inverters. Modified inverters are best suited for resistive loads which don’t have a start up surge. Pure Sine wave inverters should be used for televisions, laptops, digital microwaves, fridges and other sensitive electronic equipment. 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).

Beware!

Sale of inverters is a long-standing and competitive market. Beware of unbranded inverters which have very high wattage output and appear to be very good value. There are reports that 75% of unbranded inverters cannot achieve anywhere near the specified power outputs. 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.

Technical Specification – 2000W, 24V Model

We have recommended a 24V input for this amount of output power, otherwise a 12V inverter would have 160A in the input cables with high voltage drop and expensive cables, 24V only has 80A in the input cables. 24V is acheived by using 2 X 12V batteries in series
