32 Program features
MPPT algorithm achieves this increased speed limit only if the actual DC bus voltage is
appropriate to the boost factor.
Settings
Voltage limits
The solar pump inverter operates within the voltage limits defined for PV cells and beyond
these limits the inverter trips. At maximum voltage limit, the inverter trips to a PV MAX
VOLT fault. Below the minimum DC voltage limit, the inverter stops modulating.

Speed limits
The ACS355 solar pump inverter operates within the defined speed limits set in the group
60 PUMP CONTROL parameters.
• Minimum pump speed—Below this value, inverter stops the pump operation. The
inverter restarts automatically only after the 6019 FAULT RESET TIME, see page 58.
This operation of the inverter prevents the pump from running at a low speed (where
the pump capacity drops and is near zero).
• Maximum pump speed—The pump operates within this speed limit defined by MPPT
in 6007 PUMP MAXIMUM SPD, provided that the maximum speed limit of the inverter
in 2002 MAXIMUM SPEED is equal to or higher than this value.
Note: Ensure that the pump speed is always defined within the allowed speed limit of the
inverter.
Parameter Additional information
6008 BOOST VOLT
DC voltage reference to activate boost factor.
6009 BOOST FACTOR
Factor at which the inverter functions the best.
Parameter Additional information
6004 PV CELL MIN VOLT
Minimum DC voltage below which the inverter cannot
operate.
6005 PV CELL MAX VOLT
Maximum DC voltage.
Fault Additional information
PV MAX VOLT
Fault message to notify that DC bus voltage in the inverter is
higher than the maximum DC voltage (6005 PV CELL MAX
VOLT).

- Note use two poles of the changeover switch in series to ensure that the voltage applied across each pole is half of the full dc voltage 17
- The i v curve is not constant since intensity and temperature changes during day time under constant temperature current changes linearly with intensity and voltage changes logarithmically with intensity since the voltage variation is small with respect to intensity changes maximum power varies proportionally with intensity 17
- The solar pump inverter operates in dual supply mode either with a three phase input supply from the grid or with dc input supply from pv cells a four pole changeover switch enables switching between the two supply modes at a given time only one supply pv cell or grid will be connected to the drive 17
