Saft and Nedap Cooperation Brings Effective Storage and Self-Consumption to Domestic Solar Energy Systems

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

Intersolar Europe 2012


MUNICH--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.

US Battery - Solar RE L16XC Renewable Energy Battery

Our batteries have Xtreme thick plates with (XC Diamond Plate Technology) added to them. They have been designed for hours of heavy discharge each day, followed by a fast recharge during the daylight hours. Very few batteries can take the grueling deep discharge-recharge cycle every day for long periods of time. U.S. Battery has proven time and time again that our solar battery line can stand up to this type of battery torture day in and day out for years to come. When you demand reliable energy storage count on U.S. Battery every time!
