Delta C1000 User Manual

There are 19 parameters in Grid Settings page. User can refer to Table 5-2. for the
function of each parameter.
Parameter Description
Vac High Off
Inverter will be disconnected from grid if the phase voltage of AC rises
to this value.
Vac High On
Inverter will be reconnected to grid if the phase voltage of AC drops to
this value.
Vac High Off T
If AC voltage reaches to the value of Vac High Off, inverter will be
disconnected in this time.
Vac Low Off
Inverter will be disconnected from grid if the phase voltage of AC drops
to this value.
Vac Low On
Inverter will be reconnected to grid if the phase voltage of AC rises to
this value.
Vac Low Off T
If AC voltage reaches to the value of Vac Low Off, inverter will be
disconnected in this time.
