Page 8: Warnings And Cautions
8. Warnings and Cautions Read the manual carefully before starting and retain for future reference. Any changes or modification to the wiring must be carried out by competent, skilled and suitably qualified personnel only. A qualified electrician should correctly size and install circuit breakers to protect the power supply. -
Page 9: Solar Array Selection
9. Solar array selection Before starting a selection, ensure that you have accurate data about the solar panels you intend to use. ● Maximum power voltage Vmpp or Vmp – the panel voltage under load ● Open Circuit voltage Voc – the panel voltage without load The size of the solar array required is driven by three key factors A. - Page 10 Example 1: 400W solar panel FLEXI-SOLAR 22 2.2kW P2 Pump Voc 41 volts Maximum VOC 450V 230V 3Ph Vmpp 34 volts Minimum Vmpp 200V FLC 7.4 Amps Step One 200V minimum input voltage / 34 Vmpp per panel = 5.88 panels. Round the answer up. A minimum of 6 panels will be required to achieve the necessary voltage Step Two 450V maximum input voltage / 41 Voc = 10.97 panels.
- Page 11 Example 3: 400W solar panel FLEXI-SOLAR 75 5.5 kW P2 Pump Voc 41 volts Maximum VOC 800V 415V 3Ph Vmpp 34 volts Minimum Vmpp 440V FLC 9.8 Amps Step One 440V minimum input voltage / 34 Vmpp per panel = 12.94 panels. Round the answer up. A minimum of 13 panels will be required to achieve the necessary voltage Step Two 800V maximum input voltage / 41 Voc = 19.51 panels.

10. Solar array installation. SOLAR ARRAY • The Solar array must face True North. • The solar panel angle should correspond to the latitude of the site. Consult the instructions supplied with the solar array to assist your decision regarding the best angle for your situation. As a general rule, solar panels should be more vertical during winter to gain most of the low winter sun, and flatter during summer to maximize the output. -

Page 15: Flexi Solar Installation
12. FLEXI-SOLAR installation FLEXI-SOLAR has an IP65 rating but avoid installing the controller exposed to direct sunlight or weather. Installing under the solar panels will provide protection. Ambient temperature should be maintained in the range 0- 45 deg C and humidity between 20 to 90%. At higher temperatures the output of the controller will be de-rated When installing and moving, please hold the bottom of the product, not just the casing, to prevent injury or damage to... - Page 16 Low Level Float Switch Wiring (Optional) DI2 / GND In order to avoid damage to the pump caused by dry running, a source water level float can be connected to the DI2 & GND terminals of the Flexi-Solar. Ensure the float delivers a closed signal to DI2 and GND terminals when water level is too low.

Page 19: Controller Programming
14. Controller Programming Programming should only be carried out by suitably trained personnel. Parameters randomly modified or altered in error can induce abnormal operation and have the potential to harm the controller as well as the water supply system, or even to cause personal injury or accidents. -
Page 20: Power On And Commissioning
14a. Controller Programming con’t Example: Setting the rated motor power in Parameter Group 2, address F2.01 If the controller is behaving in an unusual manner, it is highly possible that a parameter has been altered in error. In this event, navigate through each Group and every Parameter, resetting to factory default values. - Page 21 Press the START/STOP button to start the motor briefly and slowly to check whether the rotation of it is correct. If the pump is in a dry running state, the maximum running time should not exceed 15s, otherwise the pump mechanical seal may be damaged. If the direction is wrong, turn off the DC switch, then swap any two of the 3 cables connecting the motor and controller U/V/W ports.
