SigenStack for C&I installations: modular storage

A commercial and technical guide for installers and engineering companies that need to define power, capacity and architecture before requesting a SigenStack quotation.

Request SigenStack sizing

When does SigenStack fit a C&I project?

Evaluate the system when the goal is to increase self-consumption, shift energy, limit peaks, back up critical loads or integrate a microgrid. The solution is not selected by kWh alone: power, load profile, phases, grid, generator and control strategy also matter.

  • Self-consumption with storage and surplus management
  • Peak shaving and demand control
  • Critical-load backup when supported by the architecture
  • Integration of PV, grid and generator in compatible projects

Components that must be validated in the design

The professional catalogue includes SigenStack BAT 12 modules, battery controllers, bases, covers, Sigen PV hybrid inverters and Gateways for C&I architectures. Exact configuration, compatibility and component quantities are verified for each project.

  • SigenStack BAT 12: 12 kWh battery module
  • Battery Controller and required charge/discharge rate
  • Hybrid inverter, Gateway and protection according to the single-line diagram
  • Communications, EMS, metering and commissioning

Minimum data required for a proposal

A useful quotation requires real project data. A monthly bill alone is not always enough to define the best power or capacity.

  • Hourly or 15-minute load curve
  • Contracted power, maximum demand and penalties
  • Existing or planned PV production
  • Goal: savings, backup, zero export or microgrid
  • Single-line diagram, voltage, phases, space and environmental conditions

Frequently asked questions

What is the difference between kW and kWh in SigenStack?

kW indicates the instantaneous power the system can deliver or absorb; kWh indicates stored energy. Both values must be sized against the load profile and operating goal.

Can SigenStack work with an existing PV installation?

It depends on the architecture, inverters, metering point and goal. Review the single-line diagram and existing-system compatibility before defining an AC- or DC-coupled solution.

Does SigenStack support industrial backup?

It can form part of compatible backup architectures, but critical loads, starting power, autonomy, switching, protection and Gateway must be defined. The entire installation does not necessarily need backup.

What do I receive when requesting a study?

An indicative proposal covering architecture, power, capacity, main equipment and data still to be validated. The final quotation depends on the project’s technical and commercial information.
