Nedap's PowerRouter with Dynamic Feed-in Limiter - the solution for the German EEG 2012

Groenlo, Niederlande (ots) - With the Dynamic Feed-in Limiter for
the PowerRouter, Nedap offers a unique solution to diminish the
consequences of the new German EEG 2012 law for the system owner. The
Dynamic Feed-in Limiter controls the flow of generated solar energy,
so that it is used directly to feed connected loads. Only the surplus
of energy is fed to the grid. A sensor measures the actual grid
current, which enables the PowerRouter to comply with the German 70%
reduction law at the point of feed-in instead of the output of the
inverter. Thus, by controlling the output power in an intelligent
way, reducing the output power of the inverter and loss of revenues
can be avoided. This solution is nominated for the Intersolar AWARD
2012.

Sensor measuring the grid current

Nedap's PowerRouter is provided with an easy-to-install, clip-on
sensor, which will measure the actual grid current. This makes it
possible for the PowerRouter to match generated solar energy with the
connected load, rather than feeding it to the grid. As the reduction
of 70% will be measured at the point of feed-in, instead of the
output of the inverter, the Dynamic Feed-in Limiter will subtract
consumed energy from the maximum allowed energy (70% of the installed
solar generator). By first making an optimal use of the
self-generated energy, only the surplus of energy - the energy that
cannot be used directly - will be fed to the grid. In the case that
the 70% limit is reached, and the surplus cannot be stored in
batteries, the Energy Management Relays allows to switch on
additional loads instead of switching off or reducing solar
generation. This way, the PowerRouter is always compliant with the
German EEG 2012 reduction law and no energy is wasted.

Connected batteries

Batteries may be connected to the PowerRouter to store the surplus
of generated energy, which makes it possible to further maximize the
use of own generated energy. At times when generated solar energy is
not sufficient to supply the loads, stored energy will be used to
feed the loads. Only when the batteries are fully charged and no
energy is required, the generated solar energy will be supplied to
the grid against the (lower) feed-in tariff.

All-in-one solution

Since the PowerRouter stores generated solar energy directly,
instead of converting it to AC voltage prior to charging, the
PowerRouter can skip one conversion step, which increases the overall
system efficiency. The patented Power Backbone technology of the
PowerRouter allows renewable energy sources, batteries and loads to
interchange energy and data within one product. Thus preventing
complicated installation of separate charger- and inverter products
and external logging devices. Direct input of solar power is
converted and routed in relation to supply and demand of energy,
resulting in an efficient easy-to-use solution.
