Extralink OPIP-500W pure sine wave inverter
The Extralink OPIP-500W inverter is a device that converts the output voltage of a battery (direct current, DC) into 230 V AC (alternating current) voltage. The 230 V AC is the type of current provided by utilities for standard household appliances such as TVs, refrigerators, radios, lighting, or charging laptops/mobile phones, etc. Connecting a charged battery and then an inverter allows powering household appliances in areas where there is no access to the electrical grid; for example, in a motorhome, caravan, boat, construction site, or other remote locations. Inverters are also ideal for off-grid systems and backup power supply systems in case of unexpected power outages.

This is a pure VAC output, which means 0 distortion. It harmonically follows the smooth sine wave and is almost identical to the normal electrical grid. The pure sine wave is much better than square or modified sine waves for running equipment.

Advantages of the sine wave inverter:
The advantages of a wide range of sine wave inverters (compared to modified sine wave inverters) include that electric motor equipment cannot be powered by modified sine wave inverters)
- More efficient compared to modified sine wave inverters.
The presented model has a continuous power of 500 W and a peak power of up to 1000 W (the peak reserve capacity is useful when more power is needed to operate the device than for continuous operation).
Additionally, the inverter has a USB port for powering USB-compatible devices (e.g., mobile phones, tablets, laptops, MP3 players, etc.).
