Saft and Nedap cooperation brings effective storage and self-
consumption to domestic solar energy systems
Munich, June 13, 2012 - Saft and Nedap are presenting
the first commercially available system to result from their
cooperation in photovoltaic (PV) energy storage at Intersolar
2012. The new system, shipping in August, combines Nedap's
PowerRouter solar inverter with Saft's state-of-the- art
Synerion® lithium-ion (Li-ion) battery modules.
The new system enables domestic users with on-grid PV systems
to store surplus solar energy for later consumption, rather
than feeding it into the grid. It enables solar energy to be
used directly by connected domestic loads, and when output
from the PV system is insufficient, the batteries are used to
maintain continuity of supply. Only when the batteries are
fully charged and no local energy is required will surplus
energy be supplied to the grid - optimizing domestic
self-consumption. When no solar energy is available and the
batteries are at a low state of charge (SoC), energy demand
is met by the grid.
Intersolar is expected to confirm the high level of market
interest and the potential for several thousand such systems
annually in Germany alone. Visitors to the Nedap booth
(B5-270) will be able to see the complete system, comprising
the PowerRouter and battery cabinet, while Saft's booth
(B3-271) highlights the Synerion® modules. Both partners are
prepared for this market to take off in the second half of
the year.
Nedap's PowerRouter combines a solar inverter with battery
management
Nedap's PowerRouter is a solar inverter with integrated
battery manager in an efficient all-in-one easy to use
solution. Its technology allows energy sources, storage media
and loads to interchange energy and data within one product
enabling the solar power produced by PV systems to be
converted and routed in relation to energy supply and demand.
Saft's Synerion® modules are optimized for PV energy storage
The 48 V Li-ion battery system comprises two Synerion® 24M
modules with battery management module (BMM) in a compact,
stand-alone cabinet offering 4 kWh nominal capacity. It
offers efficient, flexible, all-year-round energy storage to
support the highly dynamic charge and discharge cycling
profiles of renewable applications, together with a 20-year
service life.
It provides vital operation and SoC information to the
PowerRouter for optimum management, control and diagnosis.
The compact battery cabinet can be located close to the
PowerRouter, typically in a garage or basement. The complete
system has undergone thorough functional and safety testing
and meets the most stringent standards.
