PREFACE
ever.
Thanks for choosing our product, we will supply you with considerate service as well as
This product is suitable for solar photovoltaic pump system, aimed at environmental and economy market, to replace battery with retain water and without any battery components.
Photovoltaic Pump Controller receives the DC which produced by Solar Modules and then transform into AC to drive all kinds of pump directly.
It is reaction rapidly, little temperature and humidity influence, balance the system’s supply and demands, do well in energy-saving, and so on.
●Through adopting advanced MPPT technology, this product can make full use of the efficiency of the solar cell array.
● It can automatically adjust the motor speed and the water flow along with the intensity of sunlight.
● Automatic sleep when on high-water level and automatic restart when on low-water level to realize automatic control through water level.
● Can prevent pump from anhydrous idling.
● It also can enter automatically to sleep mode when the intensity of sunlight is weak (e.g. the sunset.), as well as can exit the sleep mode when the intensity of sunlight is becoming strong
(e.g. the sun rise.).
● Protect itself in trouble and improve the reliability of whole system.

Power On Sequencing:
Disconnect Q2 firstly, and then wait at least 5 minuets until controller discharge (or digital LED and all indicators extinguish ), then close Q1. Otherwise, will cause the damage of controller.
Notice:
(1) If there is no protection diode connected to the port of input-bus, it is forbidden to close photovoltaic cell switch (“Q1”) and power grid switch (“Q2”) at the same time.
Otherwise, will cause the damage of solar panels.
(2) When need to transform the power supply mode from power frequency to

4.2 Operation Process
4.2.1 Parameter setting
Three levels of menu are:
1. Function code group (first-level);
2. Function code (second-level);
3. Function code value (third-level).
Remarks: Press both the and the third-class menu. The difference is: pressing can return to the second-class menu from the will save the set parameters into the control panel, and then return to the second-class menu with shifting to the next function code
17
automatically; while pressing will directly return to the second-class menu without saving the parameters, and keep staying at the current function code.
4.2.2 Fault reset
If the controller has fault, it will prompt the related fault information. User can use to reset the fault. After fault reset, the controller is at stand-by state. If user does not reset the controller when it is at fault state, the controller will be at operation protection state, and can not run.
4.3 Running State
4.3.1 Power-on initialization
Firstly the system initializes during the controller power-on, and LED displays “SL503”, and seven indicator lights are all on. After the initialization is completed, the controller is on stand-by status.
4.3.2 Stand-by
At stand-by status, parameters of reference frequency and DC bus voltage can be display.

7.2 Common Faults and Solutions
Controller may have following faults or malfunctions during operation, please refer to the following solutions.
(1) No display after power on:
Inspect whether the voltage of power supply is the same as the controller rated voltage or not with multi-meter. If the power supply has problem, inspect and solve it.
Check the CHARGE light. If the light is off, Please ask for support. If the light is on, the fault may be lies in the switching power supply. Please ask for support.
(2) Power supply air switch trips off when power on:
Inspect whether the input power supply is grounded or short circuit. Please solve the problem.
(3) Motor doesn’t move after controller running:
Inspect if there is balanced three-phase output among U, V, W. If yes, then motor could be damaged, or mechanically locked. Please solve it.
If the output is unbalanced or lost, the controller drive board or the output module may be damaged, ask for support.
(4) Controller displays normally when power on, but switch at the input side trips when running:
Inspect whether the output side of controller is short circuit. If yes, ask for support.
Inspect whether ground fault exists. If yes, solve it.
If trip happens occasionally and the distance between motor and controller is too far, it is recommended to install output AC reactor.

8 MAINTENANCE
！ WARNING
Maintenance must be performed according to designated maintenance methods.
Maintenance, inspection and replacement of parts must be performed only by authorized personnel.
After turning off the main circuit power supply, waiting for 10 minutes before performance maintenance or inspection.
DO NOT directly touch components or devices of PCB board. Otherwise controller can be damaged by electrostatic.
After maintenance, all screws must be tightened.
8.1 Daily Maintenance

Customer should check the drive every 3 months or 6 months according to the actual environment:
(1) Check whether the screws of control terminals are loose. If so, tighten them with a screwdriver;
(2) Check whether the main circuit terminals are properly connected; whether the mains cables are over heated;
(3) Check whether the power cables and control cables are damaged, check especially for any wear on the cable tube;
(4) Check whether the insulating tapes around the cable lugs are stripped;
(5) Clean the dust on PCBs and air ducts with a vacuum cleaner;
(6) For drives that have been stored for a long time, it must be powered on every 2 years.
When supplying AC power to the drive, use a voltage regulator to raise the input voltage to rated input voltage gradually. The drive should be powered for 5 hours without load;
(7) Before performing insulation tests, all main circuit input/output terminals should be short-circuited with conductors. Then proceed insulation test to the ground. Insulation test of single main circuit terminal to ground is forbidden; otherwise, the drive might be damaged.
Please use a 500V Mega-Ohm-Meter;
(8) Before the insulation test of the motor, disconnect the motor from the drive to avoid damaging it.
8.3 Replacement of wearing parts
Fans and electrolytic capacitors are wearing part, please make periodic replacement to ensure long term, safety and failure-free operation. The replacement periods are as follows:
◆ Fan: Must be replaced when using up to 20,000 hours;
◆ Electrolytic Capacitor: Must be replaced when using up to 30,000~40, 000 hours.

*Tips
：
In fact, the application of the product is closely associated with solar sell and environment. only you correctly preset the parameters of solar cell and additional use of the parameters (“F0.02 and F0.04” ) the highest utilization efficiency can be achieved.
1. Firstly, according to the solar sell panel to preset the parameters F0.05 and “F0.06”. If you don’t want to use the terminals “ S1~S4 ”,“S1 and S2 ” must be connected to“COM”, otherwise it doesn’t work normally.
2. Secondary, presetting the lower frequency limit “F0.02” of ensuring that the pump can work in this frequency.
3. After having the lower frequency limit, you need to appropriately regulation the start-up voltage. Under the normal condition of sun light, if it starts and stops frequently, you should properly increase the start-up voltage, of course, you also can properly reduce the value of the lower frequency limit.
According to the environment as well as in combination with proper these two parameters can use solar energy more efficiency.
