• Load Manager - display text “Load Management”:
Load Manager functionality it allow you to dene congurable power
thresholds for wich the relay is activated (status: switched) to a specic
congurable power thresholds.
Once this mode has been selected, the parameters for which the relay is
activated and deactivated have to be set.
The power thresholds “Power Threshold On” and “Power Threshold Off”
refers to the inverter output Power (Pout).

LOAD MANAGER RELAY
BEHAVIOR (METER INSTALLED)
- Mode: It’s possible to select AUTO (which is the default
values for a load management working), ON (which lock the
relay in switched status), OFF (which lock the relay in rest
status).
- Power Threshold On [W]: Upper Power threshold (Pgrid/
Pout) for which the relay is activated (status: switched).
- Power Threshold Off [W]: Lower Power threshold (Pgrid/
Pout) for which the relay is deactivated (status: rest position).
- TStableThOnM (Minutes): Minimum time for which the
Pgrid/Pout shall remain above the “Power Threshold On” re-
lay activation (status: switched).
- TStableThOffM (Minutes): Minimum time for which the
Pgrid/Pout shall remain under the “Power Threshold Off” be-
fore the relay deactivation (status: rest position).
