Extralink OPIM-300W modified sine wave voltage converter

The Extralink OPIM-300W voltage converter is a device that converts battery output voltage (direct current, DC) to 230V AC (alternating current). 230V AC is the type of current provided by utilities to power standard household appliances such as TV, refrigerator, radio, lighting, or to charge a laptop/mobile phone, etc.

If you already have a charged battery then connecting an inverter will enable you to power household appliances in areas without access to the electric grid; for example, in an RV, caravan, boat, allotment or other remote location. Inverters are also ideal for off-grid systems and backup power systems in case of accidental power outages.

This is a modified sine wave inverter, which means that the 230V AC output is an approximated 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 induction motors that are used, for example, with central heating stoves.

Advantages of modified inverter:

• Less complicated design - fewer potential points of failure
• Lower price

The presented model can generate 300W of continuous power and up to 600W of peak power (peak reserve capacity is useful if more power is needed to run the device than for its continuous operation).

In addition, the inverter has a USB port for powering USB-compatible devices (e.g. cell phones, tablets, laptops, MP3 players, etc.).
