Our salt battery (sodium-ion) home storage systems in live use
We are pleased to present Europe's first sodium-ion battery projects to you. Here we want to demonstrate the first possible use cases for this new exciting technology. If you have any questions concerning your planned projects, we are happy to support you..
Single-family house with electric car
Alfons and Thomas from the Upper Palatinate built the first 32.4kWh sodium-ion pilot plant in Germany. In doing so, they connected 9 battery modules in parallel. This can be done if the battery inverter power is limited and does not exceed the maximum current of the battery module of 100A.
​Use Case: ​
-
3-phasige grid integration ​
-
11kW Wallbox
​​​​​
Key data of the project​​
-
Inverter: FSP Power Manager Hybrid 10kW
-
Storage size: 32,4kWh
-
PV-system: 29kWp
-
14kWp DC-coupled
-
15kWp AC-coupled
-
​
There are two PV systems on the house. The existing one has 15kWp PV power and a string inverter. On top of that, a new PV system with 14kWp and an FSP Power Manager hybrid inverter was installed. The energy management was realised with an energy management solution from Plexlog. Furthermore, there is an 11kW wallbox for charging the electric car.

Single-family house with heat pump
Jan, who lives in the greater Hannover area, has integrated the first test battery modules from Biwatt, each with 3.6kWh, into his PV system as an off-grid system. He is also looking into integrating the batteries into MQTT and Node-Red via Victron Cerbo GX.
​​​
Use Case: ​
-
Off-grid system (single-phase)​
-
7kW heat pump (from winter)
​
Key data of the project ​​
-
Inverter: Victron Multipus II (5kW) + MPPT
-
Storage size: 10,8kWh
-
PV-system: 6kWp​
​​
Jan is already operating a lithium iron phosphate (LFP) storage system and has come up with a sophisticated concept for using both storage technologies. The LFP battery system is already controlled by a Victron Mulitplus II inverter. Another Multiplus II was installed to integrate the sodium-ion battery. This separate circuit is operated as an off-grid system. This has the advantage that the battery charging voltage of the Mulitplus II can even be reduced to 35V, and 94% of the battery capacity can be used. A DC/DC step up connverter was also connected between the battery units to enable equalisation charging between the lithium and sodium battery system.​​​​​​​​​​​
