Solar Back-up Systems

We need electricity for the many comforts of modern life – from lighting, to appliances like refrigerators, air conditioners and heating units. So it pays to have a back-up system, especially in hospitals, schools and public buildings, but also in your own house. In the event of grid failure, the back-up system powers up immediately to continue supplying your critical machines and appliances.

1. Solar modules

The solar modules on your roof silently convert sunlight into emissions-free direct current.

2. Inverters

The direct current produced by the solar modules is then converted into grid-compatible alternating current and fed into the local grid.

3. Grid feed electricity meter

The grid feed electricity meter is installed next to your existing electricity meter. It measures the amount of electricity in kilowatt hours that you feed into the public grid and indicates how much you’ve produced.

4. Electricity meter

You continue to draw electricity for personal use from the public grid. It is measured like always by the electricity meter and billed by your energy provider.

5. Backup-Inverter

In case the 230V grid goes dark, the back-up inverter powers up to supply solar electricity until the public grid is normalized.
