Please set the following parameters for Single Line Keypad Display Models and Double Line Keypad Display Models:
PV Mode
Make sure that PV Mode has been enabled:
- FE-00 / A1-00 = 1
Low Voltage Protection
Set the Sleep and Wake-Up Voltages of the drive (as well as Recovery Time).
- FE-16 / A1-19: Sleep Voltage (Dormancy Voltage) – ideally set this slightly higher (this setting refers to DC Supply Voltage, which can generate an AC Output = DC Supply/1.414)
- FE-17 / A1-20: WakeUp Voltage (Dormancy WakeUp Voltage) – ideally set this slightly higher (this setting refers to DC Supply Voltage, which can generate an AC Output = DC Supply/1.414)
- FE-18 / A1-21: WakeUp Time (Dormancy WakeUp Time) – ideally set this slightly longer to reduce the potential number of starts/stops per hour/day (default value is only 60s).
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 (Sleep Frequency).
- FE-19 / A1-22: Frequency of Low Frequency Protection (Sleep Frequency) – 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-20 / A1-23: Low Frequency Detection Time (Sleep Delay) – ensure that this is set to be longer than the Acceleration Time (F0-17 / b0-21), otherwise it might cause the Solar Drive to go into sleep mode during start-up.
- FE-21 / A1-24: Low Frequency Protection Automatic Recovery Time (WakeUp Time) – ideally set this slightly longer to reduce the potential number of starts/stops per hour/day (default value is only 60s).
Dry Run Protection
Set the Dry Run Protection (if required) Settings (FE-22 ~ FE-24 / A1-25 ~ A1-27):
- FE-22 / A1-25: Underload Detection Current (Dry Run Current) – set higher than the dry run / no load running current of the motor.
- FE-23 / A1-26: Underload Delay Time (Dry Run Detection Time) – ensure that this is set to be longer than the Acceleration Time (F0-17 / b0-21), otherwise it might cause the Solar Drive to go into sleep mode during start-up.
- FE-24 / A1-27: Underload Reset Delay (Dry Run Recovery Time) – please increase this time as required, default value is only 60s (depends on water level recovery time).
Motor Overcurrent Protection
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 (Over Current Detection Time) – if set very short this could cause unwanted over current alarms for short/sudden load changes.
- FE-27: Overcurrent Reset Delay – please increase this time as required (ideally much longer), default value is only 60s.
*Please Note: When using a Solar Drive in AC Mode (FE-00=0), then the above Overcurrent Protection settings will not be active, to set Overcurrent Protection when using AC Mode, please use the following settings and wiring:
- Wiring: Wire DI3 and to TA2 and TC2 to COM
- F4-02: DI3 Function = 48 (External Stop Terminal)
- F8-36: Output Current Over Limit (example: set as 105%)
- F8-37: Output Current Over Limit Detect Relay Time (example: set as 30s)
- F5-02: Relay 2 (TA2 and TC2) = 36 (Output Current Exceeded)
Fault Auto Reset Times
Update the Fault Auto Reset Parameter:
- F9-09 / bb-09: Reset Times = 0
Output Phase Loss Protection
Update the Output Phase Loss Protection Parameter:
- For SP3 Series set F9-13 / bb-13 = 1
- For SP1/S Series: If Motor Selection FE-03 = 0 (for 3-Phase 230V Motor) or FE-03 = 2 (for Single-Phase Motor without Capacitor), update the Output Phase Loss Protection Parameter: F9-13 = 1 (otherwise keep it = 0).
Free Stop Mode
Update the Stop Mode Parameter:
- F6-10 / b1-07: Free Stop = 1
*When using Deceleration instead of Free Stop it can cause Err08/09 errors if the drive is unable to decelerate quick enough during sudden PV power supply losses.
*Please Note: When using a Solar Drive in AC Mode (FE-00 = 0 / A1-00 = 0), all the FE / A1 Parameters and features are not applicable/active. Also, when using a Solar Drive in AC Mode the Input Phase Loss Protection also needs to be activated (deactivated by default since it’s not applicable when using PV Input), please set parameter F9-12 = 11 / bb-12 = 11).
Please Note: Using Multiple Drives with a Single Array
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 (as well as Delay/Recovery Times) to ensure they don’t start/stop simultaneously.
- FE-16 / A1-19: Sleep Voltage (Dormancy Voltage) – ideally set this slightly higher for the larger drive (or drive that typically needs to go into sleep mode first)
- FE-17 / A1-20: WakeUp Voltage (Dormancy WakeUp Voltage) – ideally set this slightly higher for the larger drive (or drive that typically needs to WakeUp last)
- FE-18 / A1-21: WakeUp Time (Dormancy WakeUp Time) – ideally set this slightly longer for the larger drive (or drive that typically needs to WakeUp last)
- FE-19 / A1-22: Frequency of Low Frequency Protection (Sleep Frequency) – ideally set this slightly higher for the larger drive (or drive that typically needs to go into sleep mode first)
- FE-20 / A1-23: Low Frequency Detection Time (Sleep Delay) – ideally set this slightly shorter for the larger drive (or drive that typically needs to go into sleep mode first)
- FE-21 / A1-24: Low Frequency Protection Automatic Recovery Time (WakeUp Time) – ideally set this slightly longer for the larger drive (or drive that typically needs to WakeUp last)
