Used for setting key parameters of solar pump inverter system.
Table 8-9 DESCRIPTION of DSP parameter setting
DSP Parameter
Setting Information
Motor current protection value, reference pump motor
nameplate set this parameter, recommended to be equal
to 1.2 times the rated current value of the motor.
This value represents the operation mode of the inverter:
"Economy": the inverter is in the economic mode, and the
system automatically selects the grid energy intervention
according to the photovoltaic energy;
"Reliable": the inverter is in the reliable mode, the system
detects the power grid input, that is, uses the power grid
energy to ensure the maximum frequency operation of
the inverter;
"Group control": the inverter is in group control mode,
and the inverter operates as a slave machine;
Dry protection power, which shall be reset when the load
power rating is lower than Solar pumping inverter.
Recommended value is 40% of the rated output power of
Inverter. For example, the D-Power of 2.2kW pump is
880w.
Dry out recovery time, under auto dry out mode, after the
warning of dry out and inverter shut down, the duration
from shut down to restart. Default value is 30. Default
duration is 30 minutes.
