PV300 solar pump inverter specification 

H9 solar pump control special parameters
H9.00 Solar pump control



When it set to 0, the solar pump control function is disable, it used for normal motor speed control VFD.

When it set to 1, the solar pump control function is activate, H9 and HF group parameters is useful.

DI#51 solar pump control disable set by terminal function is priority than this setting.

H9.01 Vmpp voltage reference

0: Voltage reference (CVT) The reference voltage is set by H9.02, it is a constant value, the target frequency will increase tar wards to H9.04 upper limit frequency of PI when DC voltage is higher than H9.02, and target frequency will decrease tar wards to H9.05 lower limit frequency of PI when DC voltage is lower than H9.02.

1: Max. power point tracking(MPPT)

When it set 1, adopt MPPT function, inverter always pursuing maximum power point. H9.02 value is chaning always due to MPPT function, C0.34 can monitor the MPPT voltage value(H9.02 value)

Whatever control model has been selecting, the target frequency will change towards to upper limit of PI, when the DC bus voltage is lower than this setting, the target freqeuncy will change towards to lower limit of PI output frequency.

H9.02 Vmpp set by keypad reference


When H9.01=0, the DC bus control voltage target setting.

When H9.01=1, MPPT calculating entry point setting.

If user set it for actual Vmp of solar arrays, or 80% of Voc value, the inverter can able to quick enter MPPT calculating for better performance.
