Extralink OPIP-1500W pure sine wave inverter
The Extralink OPIP-1500W inverter is a device that converts the output voltage of a battery (direct current, DC) into 230 V alternating current (AC). 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.
If you already have a charged battery, connecting the inverter allows you to power household appliances in areas where there is no access to the electrical grid; for example, in a motorhome, caravan, boat, campsite, 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 V wave, which is the 2nd. The AC output harmoniously follows the smooth sine wave and is almost identical to that of the normal electrical grid. The pure sine wave is much better than the square or modified sine wave for running equipment.

Advantages of the sine wave inverter:
The advantages of the wide range of sine waves: in the case of inverters, devices (for example, electric motor devices cannot be driven by modified sine wave inverters)
- More efficient compared to modified sine wave inverters.
The presented model can produce 1500 W continuous power and up to 3000 W peak power (the peak reserve capacity is useful when more power is needed to operate the device than for continuous operation).In addition, the inverter has a USB port for powering USB-compatible devices (e.g., mobile phones, tablets, laptops, MP3 players, etc.).
