The P2 Solar Pump Drive The P2 Solar Pump Drive is a dedicated variable frequency drive designed to take power from a photovoltaic (PV) array (DC) and operate a three phase electric pump. The in-built MPPT controller within the drive maximises the output of the pump (the flow) depending on the power available from the PV array under the varying environmental conditions.
Ensure that all terminals are tightened to the appropriate torque setting. Do not attempt to carry out any repair of the Optidrive. In the case of suspected fault or malfunction, contact your local Invertek Drives Sales Partner for further assistance.

Description Default Typical P1-01 Maximum Frequency / Speed 50.0Hz 50.0Hz Maximum output frequency/speed of the drive in Hertz (units will change to rpm if the motor rated speed has been entered into P1-10). This parameter is usually set to the rated frequency of the motor but can be adjusted above or below this value if necessary for the application. If this parameter is set above the motor rated frequency, it should be confirmed that the motor current does not exceed the motor rated current.

It is also beneficial to set up the drive to accelerate up to minimum speed quickly with the MPPT disabled so that submersible pumps with thrust bearings will not become damaged during slow starts. This method of starting can also help to force the drive into the low power standby detailed in section 6.2.4.

9.2. Parameter Group 3 – PID Control 9.2.1. Overview Optidrive P2 Solar provides an internal PID controller. Parameters for configuration of the PID controller are located together in Group 3. For simple applications, the user needs to only define the setpoint source (P3-05 to select the source or P3-06 for a fixed setpoint), feedback source (P3-10) and adjust the P Gain (P3-01), I time (P3-02) and optionally the differential time (P3-03).

Parameter Name Minimum Maximum Default Units P3-11 Maximum PID Error to Enable Ramps 25.0 Defines a threshold PID error level, whereby if the difference between the setpoint and feedback values is less than the set threshold, the internal ramp times of the drive are disabled. Where a greater PID error exists, the ramp times are enabled to limit the rate of change of motor speed on large PID errors, and react quickly to small errors.

11.2. Output Power and Current ratings The following tables provide the output current rating information for the various Optidrive P2 models. Invertek Drives always recommend that selection of the correct Optidrive is based upon the motor full load current at the incoming supply voltage. The PV DC Spply Fuse rating and type can be calculated based on the drive rated output current multiplied by the rated output voltage divided by the array Vmpp.
