With great efficiency, the solar inverter converts the direct current produced at the solar panel modules into the alternating current. In turn, this is fed into the house grid without further loss during normal operation. If there is a grid failure, the Backup Set becomes active automatically: the switching feature separates the solar plant and electric devices from the grid safely.
While the system switches to stand-alone operation, the most important loads, such as lamps, heating devices and freezers, are supplied from the battery with only 50 milliseconds pause at most. Due to the presence of the solar plant, the battery usually only has to bridge the night hours. Acting as the system manager, the backup device coordinates all switching operations, namely the disconnection from the grid and the switching over of the solar plant. In this way, every grid failure is compensated reliably.
Regardless of the location of the back-up system, the Remote Control allows the reading of all data, and the switching over to stand-alone operation. This is a comfortable solution if the system is located in a basement or under a staircase with difficult access. We also include a power management device to regulate peak power demand.
