Extralink OPIM-1000W modified sine wave inverter
The Extralink OPIM-1000W 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, etc. alt="">
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 modified wave, 20 V. The AC output is a quasi-sine wave. This solution is cheaper than pure sine wave inverters; however, due to the current output characteristics, it is not recommended for use with inductive motors, such as those used in central heating stoves.

Advantages of the modified inverter:
- Less complex design – fewer potential failure points
- lower price

The presented model can produce 1000W continuous power and up to 2000W peak power (the peak reserve capacity is useful when more power is needed for the device to operate than for continuous operation).
Additionally, the inverter has a USB port for powering USB-compatible devices (e.g., mobile phones, MP3 players, tablets, etc.).
