Description
mode
The system automatically manages power flows in or-
der to maximise self-consumption. All unused power
Self from domestic loads will feed into the grid. Using the
consumption Load Manager Relay, with the optional COM KIT, to
program a power-on/power-off of a specific Load is it
possible to increase the Self-consumption ratio
The system automatically manages power flows in or-
der to avoid the injection of energy to the grid. If the me-
Zero injection ter is disconnected or not working the inverter's output
power is restricted to zero in order to avoid accidental
power feeding to the grid.
The system automatically manages power flows in or-
der to avoid feeding the grid with power greater than:
Configurable where P
("PV GENERATOR POWER" parameter) and P
output power limit with respect to P
POWER" parameter).
- PV GENERATOR POWER: Insert the power value of the photovol-
taic system (kWp) installed.
- FEED-IN POWER: Set the percentage AC power restriction (with
reference to the value of the photovoltaic system (kWp) installed)
to be feed into the grid. This field can be edited only if the Energy
Policy selected is "Configurable".
Confirm the settings by clicking "END" and the inverter will test the meter
working.
