The largest financial savings will be achieved if the
power generated by the fuel cell module is consumed
on site. The energy manager optimises the fuel cell
module runtimes subject to power and heat consump-
tion within the building.
Operation with energy manager
The start times and runtimes of the fuel cell module
are adjusted to the times when you routinely require
power. This increases utilisation of power generated
on site.
You can choose from 2 operating strategies:
■
"Ecological"
: The optimal start point for the fuel cell
module is calculated using specific emission factors
to achieve the lowest possible CO
2
emissions.
■
"Economical"
: The optimal start point for the fuel
cell module is determined by the power supply price,
feed-in remuneration and gas price.
When there is no installed electricity meter, the energy
manager refers to a stored standard load profile as the
specific power consumption is unknown.
Operation without energy manager
The start times of the fuel cell module depend only on
the heat demand of the system.
Information on operation with power storage unit:
If the building mains has been disconnected from the
public grid (e.g. power cut), we recommend switching
off the energy manager.
