Configuring the Operating Mode

Damage to the PV inverters, gensets, or loads caused by the input of incorrect setpoints
In Manual mode, the setpoints for the PV inverters and the reserve power to be kept by the gensets are specified via
the user interface. If the specifications are incorrect, the technical thresholds of the PV inverters, gensets, or loads can
be exceeded. An exceeding of technical thresholds can lead to damage of the PV power plant, gensets or loads.
• For continuous operation of the Fuel Save Controller, always use the automatic operating mode.
• Only activate the manual operating mode in temporary and exceptional situations (e.g., when carrying out
maintenance).
• In the operating mode, verify that the technical thresholds for PV inverters, gensets, and loads are being
adhered to:
– For the manual operating mode, at least 2 persons must be present at all times and must be trained in the
use of the manual operating mode.
– Both persons must continuously monitor the adherence to technical thresholds during manual operating
mode via the Fuel Save Controller user interface.

Specification of Setpoints for PV Power Plant by SCADA System

When this function is active, a SCADA (Supervisory Control and Data Acquisition) system specifies the setpoints for the
PV power plant and the reserve power to be retained by the gensets in the Fuel Save Controller. The
Fuel Save Controller checks these setpoints. Should the setpoints issued by the SCADA system jeopardize the stability
of the PV diesel hybrid system, they will be corrected by the Fuel Save Controller. Finally the setpoints are forwarded to
the PV power plant by the Fuel Save Controller.
Procedure:
1. To do this you must be logged in as Installer: Go to the menu Plant Overview via the page and menu selection.
2. Choose Operations > Mode via the page and menu selection (see Section 6.9.1 "Overview of Operating
Modes and Setpoints", page 41).
3. In the Control Mode area activate the Enable SCADA to send setpoints checkbox.
