1. Introduzione
The Volt Polska SINUS 3000 12/230V Pure Sine Wave Inverter is designed to convert 12V DC power from batteries or vehicle electrical systems into 230V AC power. This device is ideal for powering electrical appliances that require a pure sine wave output, similar to the mains electricity grid. It is particularly well-suited for use in vehicles such as campers, and in locations where direct connection to the power grid is not available.
This inverter features a pure sine wave output, making it compatible with inductive loads such as power tools, air compressors, air conditioners, refrigerators, and freezers. The PLUS version includes a remote control panel with a cable, allowing for convenient remote operation.
