Please set the following parameters for Single Line Keypad Display Models and Double Line Keypad Display Models):
Make sure that PV Mode has been enabled:
- FE-00 / A1-00 = 1
Make sure that all Motor Parameters has been set (F1-01 ~ F1-05 / d0-00 ~ d0-04):
- F1-01 / d0-00: Motor Rated Power
- F1-02 / d0-01: Motor Rated Voltage
- F1-03 / d0-02: Motor Rated Current
- F1-04 / d0-03: Motor Rated Frequency
- F1-05 / d0-04: Motor Rated Speed
Also make sure to set the Motor Overcurrent Protection Settings (FE-25 ~ FE-27 / for Double Line Keypad Display Models this is based on d0-02):
- FE-25: Overcurrent Detection Current
- FE-26: Overcurrent Delay Time
- FE-27: Overcurrent Reset Delay
Low Frequency Protection: To protect motors from running too slow during low sunlight periods (especially for borehole applications), please adjust the detection frequency of low frequency protection. The default = 10 or 15Hz (depending on model), adjust it to ~ 25Hz (please confirm with the pump manufacturer what the lowest acceptable speed for the pump is to prevent damage). The frequency should not be set to less than the lowest speed at which the system is functional (e.g., lowest speed at which the motor needs to run before water exits the borehole).
- FE-19 / A1-22
Also make sure to set the Dry Run Protection (if required) Settings (FE-22 ~ FE-24 / A1-25 ~ A1-27):
- FE-22 / A1-25: Underload Detection Current
- FE-23 / A1-25: Underload Delay Time
- FE-24 / A1-25: Underload Reset Delay
*When using a single PV Array and connecting multiple Solar Drives to the same array, please adjust the Sleep and Wake-Up Voltages and Frequencies of the drives to ensure they don’t start/stop simultaneously.
- FE-16 ~ FE-21 / A1-19 ~ A1-24
*Perform Auto tuning if applicable/required.
