Function 3.1
The VARTA pulse energy storage system is intended for use on a
AC household electrical system and is capable of being connected
to a separate grid-coupled photovoltaic system. This must be a
generating unit which supplies to surplus rather than to full feed.
There is also provision for storing renewable energy, for example
from small wind turbines or other energy sources such as CHPs.
The energy stored system is intended to increase the in-house
consumption percentage and the economy of a photovoltaic
system. If the photovoltaic system generates more electricity than
immediately needed, it can be stored temporarily in the energy
storage system. The electricity will be fed into the building grid, as
soon as the consumption rises again above the electricity
generated by the photovoltaic system.
The energy storage system is integrated into the building grid as
an AC connection and operates independently of the photovoltaic
system. A current sensor controls the charge and discharge
processes of the energy storage system. It is mounted in the fuse
box, directly behind the consumption/feed-in meter, and measures
all incoming and outgoing currents.
If the current sensor measures outgoing currents in case of
available free charge capacity of the energy storage system, it will
be charged. During the process, the battery inverter inside the
energy storage system converts AC to DC and charges the battery
module. If the maximum charge capacity is reached, or the solar
electricity exceeds the maximum charging current, the surplus
solar electricity is fed into the public grid. If the photovoltaic system
is not able to cover the current electricity demand inside the
building, the current sensor measures incoming currents. As a
