The WhisperPower WP-Sine-12-1000 is an electrical inverter which takes a direct current (DC) input and changes this into an alternating current (AC) output. This means it can be connected to a 12V DC battery and produce a 230V AC current to power regular household appliances on board boats, recreational vehicles, caravans and holiday homes.

Unlike many other power inverters, the WhisperPower WP-Sine produces a true, high frequency sine wave output to exactly replicate domestic current. This ensures appliances are powered in the way that they were designed and will not be damaged through improper use. Despite replicating true sine wave, the unit is silent in operation and is a very compact size.

The WhisperPower inverter will regulate the AC output to appliances to ensure they don't get damaged, it supplies a constant voltage and never supplies too much. A temperature sensor is provided which will provide information to shut down the inverter if the battery is too hot. The inverter is also programmed to shut down automatically if the battery reaches a low level to ensure it is not discharged fully.

The body of the inverter features an LED display on the side which provides information on battery voltage, inverter AC output and any error messages that arise. It will also display a green, amber or red status light to indicate whether the unit is running normally or not. This WP-Sine-12-1000 model features one UK socket located near this display as well as a USB port used to charge items like mobile phones and cameras.
