Storing energy. Managing energy.
Solar independence with the Powador-gridsave system.
Now nothing stands in the way of environmentally friendly solar power that
is available around the clock. The Powador-gridsave stores solar power during
the day and makes it available for later
use. Thus, the Powador-gridsave closes
the time gap between power generation
and power consumption.
The Powador-gridsave is an energy storage system that is best suitable for integration in new photovoltaic plants. Connection to existing photovoltaic plants
is also possible. It combines the battery,
controller and interface of the photovoltaic plant into one compact system.
A stable supply of power is taken
for granted, but local power failures
throughout Europe, including Germany,
cannot be ruled out. Conventional gridconnected photovoltaic plants cannot
guarantee a reliable supply of power at
the present time, since feed-in inverters
are immediately disconnected from the
grid for safety reasons when there is a
power failure. Integrating the Powadorgridsave in a grid-connected system remedies this situation. The grid-connected
photovoltaic plant is turned into a solarfed energy centre: In case of a power
failure, the energy management system
(EMS) switches to standalone mode
and disconnects the in-house grid from
the public power grid. The photovoltaic
plant and the Powador-gridsave are now
used as an energy source that can directly supply power to electrical devices or
charge batteries.
