The inverter converts a DC voltage of 12/24 V into AC voltage 230 V/50 Hz pure sine wave. Through internal protection functions, battery, inverter and consumers are protected during operation. Optimal for sensitive consumers which require a pure sine wave for their operation. Comes with lead wire and ring terminal. (Version with 300 W has crocs). When installing in vehicles (non-earthed neutral) we recommend for your own safety that you install an insulation monitor (VDE 0100-410 and EN 60204-1).
