SINACON HC

Reduce system complexity, component count and cost while increasing efficiency. SINACON HC is the AC grid inverter that connects up to three DC sources (e.g., PV, batteries, etc.) simultaneously for clean and reliable power on  public grids.


Rely on SINACON HC – the efficient hybrid converter for innovative grid applications

SINACON HC is a ready-to-run grid converter with all required grid functionalities. This converter combines renewable energy source and storage within one unit for diverse applications. The innovative product concept with its high operational flexibility gives the user optimization benefits for on-grid and off-grid operation.

The SINACON HC converter’s universal capability combined with its high-performance architecture and advanced control features is the Siemens answer to the challenges of a rapidly growing distributed energy market.

Components are sourced from the U.S. and the widereaching Siemens global supply chain and assembled in our Alpharetta, GA, assembly center. U.S.-centered production makes it easy to confirm firsthand our quality materials and manufacturing process. It allows for shorter production timelines, transitioning quickly from specs to provisioning to an up-and-running installation. And if replacement parts are needed, they can be provided quickly and efficiently, reducing your risk of disruption to smooth delivery of power.
