When using a storage system in photovoltaic diesel hybrid systems: Measurement of PV power via
the measurement inputs of the Fuel Save Controller
If a storage system is implemented in the photovoltaic diesel hybrid system, the Fuel Save Controller has to
calculate the setpoints of the storage system for the charging and discharging of the battery depending on the PV
power. To correctly calculate the setpoints, the Fuel Save Controller requires the data of the PV power in a very
high temporal resolution.
For this, a current measurement input and a voltage measurement input of the Fuel Save Controller or of the
optional Data Acquisition Module must be used for capturing the PV power. The data transmitted via the internal
communication network of the PV diesel hybrid system do not have the required resolution.
In the basic configuration of the Fuel Save Controller, only the terminals X700:1 to X700:13 are available for current
measurement (see Section 6.1.2 "Interior View", page 19).
