DETAILED PARAMETER DESCRIPTION
P1139 - Apparent power at the inverter input
Acesso: Menu → Status → Measurements → Power
Description:
Indicates the apparent power in the inverter input, in kVA.
The total power in the input is calculated according to the equation below:
P1139 =
√
3 × P1136 × P1137
Being:
P1136 = Inverter input current;
P1137 = Inverter input line voltage.
P1140 - Active power at the inverter input
Acesso: Menu → Status → Measurements → Power
Description:
Indicates the real power in the inverter input, in kW.
Positive numbers indicate that the inverter is consuming power from the power grid.
Negative numbers indicate that the inverter is regenerating power to the power grid.
The real power in the input is calculated according to the equation below:
P1140 =
√
3 × active current × P1137
Being:
P1137 = Inverter input line voltage.
P1141 - Reactive power at the inverter input
Acesso: Menu → Status → Measurements → Power
Description:
Indicates the reactive power in the inverter input, in kVAr.
In P1137 you can see the angle between voltage and current in the inverter input.
The reactive power in the input is calculated according to the equation below:
P1141 =
√
3 × reactive current × P1137
Being:
P1137 = Inverter input line voltage.
