Notes for Safe Operation
■Before Installation
WARNING
Do not install or operate the controller which is damaged or has missing parts.
Otherwise, it may result in equipment damage or life harm.
■ Installation
CAUTION
◎Hold the bottom of the controller when installing or moving the controller, you must
not just hold the shell，in order to prevent the injury or breaking of controller.
◎Install the controller on nonflammable material like metal. Otherwise it may cause a
fire.
◎When the controller is mounted in a protective cabinet, the cabinet needs to set vents
to ensure ambient temperature is below 40℃,Otherwise it may be damaged because of high
temperature.
◎When installing the controller, you should avoid direct sunlight, the controller can be
installed under the PV arrays.
WARNING
◎Ensure only qualified personnel can install and operate the controller. Otherwise it can
cause an electrical shock or damage of the controller.
◎Make sure the controller is isolated from power supply by the circuit breaker. Otherwise
it may cause a fire.
◎Make sure that the ground terminal is grounded correctly.
◎Do not touch the power input terminals or the pump’s terminals . Otherwise it may
cause an electrical shock.

■ Operation
CAUTION
◎Do not open or remove the front cover during operation. Otherwise it may cause an
electrical shock.
◎Before testing the pump must be installed; you cannot make the pump dry-run for a long
time. In order to test the pump, the maximum dry-run time is not more than 15s
◎If the pump turning is reversed, it can change any two cables of the pump’s three power
cables.
◎When the water pump is stopped due to the light shadow, it will restart the operation
after 300s.
◎If a water level probe is installed in the well, when the water level is below the level of
water shortage, the water pump will stop. If there is no water level probe, it will need to be
short connection of controller’s related terminals. If a water level probe is not used, the
controller’s terminals must be short connected
■ Maintenance and check
WARNING
◎Only qualified or authorized professional personnel can maintain, replace and inspect
the controller. Otherwise it may cause damage and injury.
◎Wait at least 10 minutes after the power failure, or make sure that is no residual voltage
before carry out maintenance and inspection, otherwise it may cause damage.
■Others
WARNING
◎Failing to follow these instructions, which result in damage to the machine, cannot
enjoy the warranty service.

Chapter 1 How It Works
The PDS33 solar pumping system serves to provide water in remote applications
where electrical grid power is either unreliable or unavailable. The controller can
convert DC power from the PV array to AC power，and drive variable kinds of
pumps. In sunny days, the PDS33 solar pumping system can continuously pump
water. The system is without batteries and other energy storage devices, it is
recommended to take water to a reservoir for later use and water sources are those
natural or special such as river, lake, well or waterway, etc. A float switch can be
installed in the water tower to control the pump operation. And install a low-level
probe in well to detect the well water so that when the water shortage pump is
stopped. Figure 1 shows a typical diagram of a PDS33 solar pumping system. The
major parts and components in the system are listed after the diagram.
Figure 1 PDS33 solar pumping system
The PDS33 solar pumping system is designed which consists of:
A. Solar Array
PDS33 Series

B. DC Breaker or Disconnecting Switch
C. PDS33 series Solar Pump Controller
D. Pump and Motor
E. Water Source Level Switches (optional)
F. Tank Level Switches (optional)
The PDS33 solar pump controller runs at variable speed while matching the
changing power provided by the solar array. Variable speed operation means there
is no in-rush or surge of energy during the pump/motor start-up, helping to
eliminate wear on the motor and pumping system.
Pump Check Valve Requirements
Notice: In order to ensure maximum system reliability and water delivery, check
valves must be installed in the drop pipe. The first check valve must be installed at
the pump and additional check valves should be installed every 30m (100 ft) of
vertical pipe after the pump.

1.1 Features
System Diagnostics
The PDS33 solar pump controller continuously monitors system performance and
detects a variety of abnormal conditions. In many cases, the controller will
compensate as needed to maintain continuous system operation; however, if there
is high risk of equipment damage, the controller will protect the system and display
the fault condition. If possible, the controller will try to restart itself when the fault
condition subsides. See Diagnostics and Troubleshooting section for a list of Fault
Codes and corrective actions.
Motor Soft-Start
Normally, when there is a demand for water and power is available, the PDS33
solar pump controller will be operating. Whenever the PDS33 solar pump
controller detects a need for water, the controller always “ramps up” the motor
speed while gradually increasing motor voltage, resulting in a cooler motor and
lower start-up current compared to conventional water systems. Due to the
controller’s soft-start feature this will not harm the motor.
Over Temperature Monitoring
The PDS33 solar pump controller can be operated at full power when the ambient
temperature reaches 45 °C. At temperatures above 45 °C, the controller reduces the
carrier frequency and maintains operation as much as possible.
Level Control Switch
The PDS33 solar pump controller can access two water level switch detects
remotely control the pump automatically. Level switch for PDS33 solar pump
controller is optional, not mandatory.
