The Steca Solarix series of sine wave inverters has proved itself time and again in over 15,000 applications. These devices have been used throughout the world.

With its compact construction and optimally integrated solar charge regulator, this ‘plug & play’ solution is easy to install. A switch on the front of the device enables the user to choose between automatic load detection mode, continuous operation or sleep mode. This can considerably reduce the standby time, which is particularly important for systems in stand-alone operation.
