The ePowerControl HFS Series is a Hybrid Fuel Saver controller and solar-diesel integration solution for power plants ranging from 100 \text{kWp} to 3 \text{MWp}.

​It maximizes PV production while ensuring zero export to the grid (grid feed-in management) and maintaining the gensets above their minimum loading requirement.

​The controller includes features like genset peak shaving, reactive power management to maintain the power factor at the Point of Common Coupling (PCC), and a fail-safe strategy triggered by communication loss.

​It offers guaranteed interoperability and multi-brand compatibility with various devices (inverters, genset controllers, etc.), supporting protocols like Modbus TCP/RTU.

​Commissioning is streamlined using the eConf² intuitive interface, and the system provides reliable data logging with secure local storage and multiple export options, including remote access via ePowerMonitor³.
