Enjoy green energy
SigenStor is a stackable energy storage system made up of three building blocks: the Sigen Energy Controller (hybrid inverter), Sigen Battery modules (SigenStor BAT 5.0 / 8.0) and the optional Sigen EV DC Charging Module. The Energy Controller is available in single phase from 3.0 to 6.0 kW and three phase from 5.0 to 25.0 kW, with 1 to 6 battery modules per controller.

¹ Load-side disruption time. To achieve this, the Sigen Energy Gateway needs to be used together with the Sigen Energy Controller and Sigen Battery. Test conditions: in the open-circuit state of the power grid, the nominal power of the Sigen Energy Controller is higher than the total power of the home loads.
² For all standards, refer to the certificates category on the Sigenergy website.
* 0 ms load-side disruption, see note 1.
