TargMaxImprtP -30,000 to +30,000 Watts
0
Maximum Threshold for importing power before the battery will discharge in
Self Supply Mode to offset.
TargMinImprtP -30,000 to +30,000 Watts
0
Minimum power import maintained by charging the battery from the grid in
Self Supply Mode.
EnaIslanding
on / off
on
Allows system to go into island mode, providing backup power during a util
-
ity service interruption. Turn this setting off for PV only installations.
NumTranSwtchs
0 / 1 / 2
0
Defines the number of external automatic transfer switches installed and
enables transfer switch controls.
For AC Coupled PV, this must be 1.
ExtTransVolt
80 – 140 Volts
95
Minimum voltage from the utility that must be present for the inverter to
reconnect back to the grid. If an ATS is installed, this will be the voltage
required for the inverter to control the ATS back to the normal (utility) posi
-
tion.
ExportOverride
on / off
off
Formerly called Zero Export, this setting will inhibit the PWRcell system
from exporting power to the grid. This setting is for temporary use and will
not satisfy CRD200 Import Only Compliance. See
.
CalOverride
on / off
off
Overrides inverter logic for automatic detection of included Generac current
transformers (CTs).
CTTurnsRatio
1,500 – 3,000 Turns
1,500
Allows a different turns ratio to be set for specific CTs.
EnaLoadShed
0 / 1 / 2
0
Select 1 if using SMM devices to shed loads. Select 2 if using the PWRcell
ATS Controller to shed loads (with or without SMMs).
GridParInvrtrs
1 – 2
1
This setting allows for two inverters to share one set of CTs. Set to 2 if daisy
chaining CTs between two inverters.
ACPVPower
0 – 7.6 kW
0
Power rating of the attached AC coupled PV array. If no AC coupled PV
array is attached leave at 0.
Set this value to the cumulative power rating of all AC coupled PV systems
connected to this inverter. This value must not exceed 7.6 kW. An incorrect
higher value will result in insufficient charging of the batteries, an incorrect
lower value will result in the possibility of an over-voltage event.
GenPower
0 – 24 kW
