Standout specification
Current Australian approvals cover both phases and a much wider model ladder than one family card implies
Show 16 model variants

These model names sit inside the family above. Capacity, phase and output still need to match the installed configuration.

EDITORIAL OPINION - BASED ON THE CITED RESEARCH
The controller is why a SigenStor quote must name more than the battery modules. A 5 kW single-phase controller and a 20 kW three-phase controller are different systems even though both are sold as SigenStor.
Best suited to
SigenStor installations where battery capacity, solar input, phase and backup are designed as one ecosystem
What stands out
Current Australian approvals cover both phases and a much wider model ladder than one family card implies
  • It is tied to the SigenStor ecosystem rather than being a general third-party battery inverter.
  • The controller rating can exceed the battery stack's available discharge power, so both limits must be checked.

Ask for these points to be answered against the exact model numbers and installed configuration in your quote.
