Chapter I Product Introduction
1.1 Introduction to Solar Pumping System
Solar Pumping System is widely applied in domestic water, agricultural irrigation, forestry
watering, desert control, grassland animal husbandry, island water supply, water treatment project,
etc. During recent years with the enhancement of new energy utilization, solar pumping system is
widely applied in the landscape and water spray system of municipal works, urban square, garden
sightseeing, tourist resort, hotel, and residential community. The system consists of solar cell array,
pumping inverter, and water pump(figure 1-1). Based on the design philosophy of saving water first,
the system omits energy storing device such as accumulator.
Figure 1-1 Structure of Solar Pumping System
The solar cell array is made from the series connection and parallel connection of several solar
cell modules, which absorb solar radiation energy and transform it into electric energy, so as to
supply electric power for the whole system. The pumping inverter controls and regulates the
operation of the system, transforms the direct current of solar cell array into alternating current to
drive water pump. In addition, according to the change of sunlight intensity, regulate output
frequency timely, to realize MPPT (Maximum Power Point Tracking). The water pump is driven by
three-phase AC motor. It pumps water from deep well, river, and lake, then inject water into water
storage tank/pool, or directly connect with irrigation system or fountain system, etc. According to
actual requirements of system and installation, different types of water pumps such as centrifugal
pump, axial flow pump, mixed-flow pump, or deep-well pump can be used.

Notice: connect water level sensor 1 and detect water shortage. Respectively connect two
signal lines of sensor with S4 and COM of I/O circuit board. When water level sensor 1 detects that
the water level of well is lower than the level set by sensor, the pumping inverter will delay for 60s,
then turn off output protection pump. The water level recovers. Wait for 600s, then the pumping
inverter re-works normally.
Notice: connect water level sensor 2 to defect whether water is full. Connect two signal
lines of sensor with S2 and COM. When water level sensor 2 detects that the water level of water
tank exceeds the level set by sensor, the pumping inverter delays for 60s and turns off output; when
water level is lower than set level, wait for 120s, then pumping inverter re-starts to work normally.

Chapter IV: Failure Diagnosis
4.1 Explanation and Solution for Fault Code
BS series solar pumping inverter has complete protection. When system suffers failure, the
inverter will take protective measures: the general protective measures are to stop the output of
drive signal of motor and forbid to re-start within a certain period.
When failure or protection happens, the failure or protection needs to reset the inverter. Power
off input power supply, then power on it. If the failure is not still settled, please contact with
manufacturer to settle it.
