In response to the growing demand for on-site energy storage to accompany residential and small business rooftop solar installations, French battery manufacturer Saft has introduced its new Intensium® Home 10M lithium-ion (Li-ion) energy storage system. The battery pack offers high performance in a modern, aesthetically pleasing design intended specifically for high-end residential and small commercial solar PV installations.

The Intensium® Home 10M has been developed to complement Saft’s established range of Li-ion energy storage systems. In a new partnership with KACO new energy GmbH, one of Germany’s leading inverter brands, Saft is offering the Intensium® Home 10M in conjunction with KACO’s new three-phase inverter. This Saft and KACO package creates an ideal solution for the growing number of home and commercial prosumers (producers and consumers) who are keen to maximize their self-consumption.

The new Intensium® Home 10M 240 V system comprises five Li-ion modules to provide both high power capability, rated at 10 kW, with 10 kWh energy storage in an aesthetically designed cabinet specific for home and commercial installations. This high power Li-ion system is ideally suited to work in partnership with KACO new energy’s blueplanet gridsave 14.0 TL3 inverter in installations up to 30 kW. This combination will help domestic and small company users boost self-consumption of their own clean energy. Prosumers will be able to follow their system’s performance on their smartphone.

Volker Dietrich, Director of Energy Systems Technology Division, KACO new energy, commented, “Saft is a leader in Li-ion energy storage while KACO new energy is a top 10 inverter brand worldwide. Together we form a strong partnership that provides customers with a total package solution fully validated by testing in real homes. This approach smooths the way to delivering an effective, fast-track energy storage and management solution. The partnership will enable Saft and KACO new energy to undertake common promotion and training, transfer of expertise, and co-use of existing sales channels.”

Intensium® Home 10M – Ready for the Swarm

Prosumer PV installation users are both producers and consumers, as they produce solar electricity and consume electricity from the grid. By adding an energy storage system, prosumers increase their solar electricity self-consumption, with a very close match between their own production and consumption.

The combination of Saft’s Li-ion energy storage and KACO new energy’s inverter offers advanced energy management with the capability to operate as part of swarm-type schemes. These swarms offer the possibility of aggregating several decentralized energy storage installations to improve grid stability by helping balance supply and demand, as well as offering financially attractive ancillary services to grid operators such as frequency control. The smart energy management system enables remote control of the storage device via Internet or other communication interfaces, for example to switch from self-consumption to frequency regulation.

Swarm applications together with self-consumption, are set to play a key role in Germany’s energy transition – the “Energiewende.” Self-consumption, rather than feeding excess solar energy into the grid, is particularly attractive to the growing number of prosumers who are keen to take an active role in managing their energy production and usage.

In Germany in particular, the outlook for self-consumption is bright. According to Germany Trade & Invest, in 2020, 29 percent of residential electricity demand and 18 percent of commercial electricity demand could be met by self-produced photovoltaic power.
