FbEq (16b/32b)
178 MPPT settings
178.03 Minimum voltage ref Sets the minimum MPPT voltage reference. 500 V
0 … 1000 V 1 = 1 V
178.04 Maximum voltage ref Sets the maximum MPPT voltage reference. 950 V
0 … 1000 V 1 = 1 V
178.12 Zero power level Sets power level in percent of nominal output
power where MPPT considers power to equal 0%
and starts to reduce the DC voltage. This avoids
MPPT from drifting at voltages above the panel
open circuit voltage.
1%
0 … 10% 1 = 1%
178.50 MPPT status word Shows the MPPT status word.
b0: MPPT MPPT is active.
b1: Limited mode Tracking is not active because active power is
limited.
b2: Minimum voltage MPPT reference is at the minimum voltage.
b3: Maximum voltage MPPT reference is at the maximum voltage.
b4...b15: Reserved
178.51 Input power Shows sum of DC string input power. -
- 100 = 1 kW
